Improvement and quality evaluation of gluten-free cake supplemented with sweet potato flour and carrot powder

Celiac disease and wheat allergy are immune-responsive small bowel disorders that respond solely to the ingestion of gluten-fortified wheat or wheat flour. As a result, for those who are allergic to wheat flour or gluten, the primary treatment is a gluten-free or wheat-free diet. The goal of this research is to develop a gluten-free cake with sweet potato and carrot powder, as well as to examine the Proximate analysis, mineral content, physical properties, and microbiological qualities determined using standard analytical procedures. To make cakes, instead of wheat flour, a combined formulation of 80 % sweet potato flour and 20 % carrot powder, 60 % sweet potato flour and 40 % carrot powder was incorporated into the cake ingredients. Quality evaluation of sample cakes was performed by physicochemical and storage properties. The proximate analysis of the data revealed that the cakes that were created contained adequate levels of protein, fiber, and carbohydrates with percentages ranging from 8.12 to 8.25 %, 3.19–4.19 %, and 36.03 to 38.25 %, respectively. Additionally, an appreciable amount of potassium, calcium, magnesium, phosphorus, and iron have been found in gluten-free cakes. There was color to the gluten-free cakes; L*, a*, and b* ranged from 42.66 to 43.60, 10.03 to 11.21, and 21.81 to 23.28, respectively. There is an assurance of a good color property because the hue and chroma values varied from 11.74 to 25.83 and from 41.02 to 78.03, respectively. The water activity (aw) value ranged from 0.854 to 0.870, which increased from 0.879 to 0.901 during storage. Furthermore, the microbial analysis revealed that the total viable count of all samples remained within the acceptable range after 8 days of storage. The findings of this study show that carrot powder and sweet potato flour can be used to overcome the limitations of gluten-free cakes and improve their nutritional quality.

Effects of maternal dietary supplementation with antioxidants on clinical status of mares and their foal

BackgroundThe peripartum period constitutes a delicate physiological moment in mares showing a transient state of oxidative stress. Diet supplementation with antioxidants during pregnancy in women appears to have a beneficial effect on mother and neonate health. The aim of this work was to evaluate the effects of diet supplementation with a commercial product containing a mix of antioxidants (Oxyliver®, Candioli) on the length of gestation, weight, and haemato-biochemical parameters in Italian Salernitano mares and their newborn foals. Eight late-term pregnant mares were randomly divided into two groups: Antiox group receiving 30 g/day of antioxidants, and Car group receiving the same amount of carrot powder, from 290 to 320 days of gestation. The following parameters were evaluated in mares: weight, colostrum composition, haemato-biochemical parameters, progesterone, and cortisol blood concentrations, along with blood oxidant/antioxidant status. Assessments were conducted at specific time points: immediately before the start of diet supplementation (T0), 15 days after (T1), at the end of diet supplementation (T2), within 8 h after parturition (T3), and 10 days post-partum (T4). Foal parameters such as weight, haemato-biochemical values, cortisol concentration, and blood oxidative stress variables were assessed within 8 h of birth (TF0) and at 10 days of age (TF1).ResultsPregnancy was shorter in the Antiox group (P < 0.05) compared with the Car group; the foals’ weight increase of group Antiox (40%) was higher (P < 0.05) compared to those of the Car group (28.6%). The colostrum of the Antiox group exhibited higher levels of Brix, total solids, protein, nonfat solids, casein, urea, density, free fatty acids, and glucose, while lower levels of fat and lactose were observed compared to the Car group (P < 0.05). Mares’ serum albumin at T1 and T3, creatinine, glucose, total proteins, total bilirubin, AST, and ALT at T3 were lower in Antiox than in the Car group. No significant differences were found in foals.ConclusionsWhile the limited sample size and the potential variability of evaluated parameters, the observed outcomes suggest that Oxyliver® supplementation in mares might safely decrease gestation length and enhance liver function, thus potentially improving colostrum quality and offspring development.

Nutritional, Anti-Nutritional and Sensory Evaluation of Snacks Produced from Germinated Maize/Bambara Groundnut (Vigna Subterranean) Flours

Background: Bambara nut, an underutilized legume is rich in protein and can improve the nutritional quality of snacks. This study evaluates the nutritional and sensory properties of muffins produced from germinated maize and Bambara groundnut flours. Methods: Maize and Bambara groundnut seeds were germinated (72 hours), oven-dried and milled. The composite flours from the germinated flours were combined with soya oil, tiger-nut milk, date and carrot powder to produce four samples of muffins. The samples were chemically analyzed for proximate, mineral, beta-carotene, and anti-nutrient contents. Then, sensory evaluation was carried out among 20 mothers (20-30) using a 5 hedonic scale. ANOVA and Duncan Multiple Range Test were also used to analyze the data. Results: Protein, fiber and carbohydrate contents of the muffins ranged from 7.63-9.23%, 0.05-0.08% and 70.63-71.55%, respectively. It was found that germination significantly increased protein and iron content of muffins but reduced zinc, calcium, and beta-carotene contents (P&lt;0.001). The muffins contributed above 22% of the RDA regarding energy for children. Muffins produced from the blends provided higher level of protein, calcium, iron and beta-carotene compared to those made from whole wheat flour. There was a significant reduction in anti-nutrient contents of the muffins and germinated flours. The muffin produced from the 80% maize and 20% Bambara nut flour was rated best in terms of nutritional value, taste, and texture. Conclusion: Bambara nut flours could be used to produce nutritious snacks which would contribute to daily energy and protein needs of children.

Effects of Incorporating Caramel, Carrot, and Tomato Powder on the Quality Characteristics of Soy Protein-Based Meat Patties.

Plant protein-based foods have become dietary preferences worldwide, and the quality of this food group is highly associated with the ingredients used. This study investigated the effects of incorporating caramel, tomato powder, and carrot powder on the product quality of soy protein-based meat patties (SPMPs). The color, total phenolic content (TPC), antioxidant activity, lipid oxidation, and texture profile of uncooked and cooked soy protein meat patties were analyzed. Among the cooked SPMPs, caramel SPMPs exhibited the lowest color difference (ΔE) values, and the ΔE value of tomato SPMPs was lower than that of carrot SPMPs, indicating that caramel has the best color stability, and the tomato experienced less color change than the carrot during cooking. Notably, carrot SPMPs exhibited lower color stability during refrigeration storage than the others. Both carrot and tomato powders increased the total phenolic content (TPC) and antioxidant stability and inhibited lipid oxidation in SPMPs during cooking. However, tomato SPMPs exhibited higher TPC values and greater antioxidant stability compared to carrot SPMPs. The addition of caramel and carrot powders decreased the hardness of raw SPMPs, but tomato powder increased the hardness. The texture profile of tomato SPMPs was more affected by the cooking process compared to caramel and carrot SPMPs. This study showed that incorporating both carrot and tomato powders positively influenced the quality characteristics of SPMPs compared to caramel powder, however, tomato powder exhibited superior efficacy.

Evaluation of chapattis fortified-diet with raw and fermented carrot powder in persons with type 2 diabetes: A randomized control pilot study

BackgroundDiabetes is a metabolic disease that is common and growing rapidly. It is characterised by high blood sugar levels and related complications to vital organs such as the kidneys, heart, blood vessels, and eyes. The most common kind of diabetes affecting people globally is type 2 diabetes (T2D). An increasing number of people are looking at natural foods and dietary supplements to manage their T2D.ObjectiveThe aim of this pilot study was to assess the glycemic index, glycemic response, sensory qualities, nutritional composition, and possible antidiabetic benefits of chapattis fortified with raw and fermented carrot powder.MethodsSeven preparations of chapattis were prepared into three variants from whole wheat flour chapattis (WWFC) as control group, raw carrot-supplemented chapattis (RCSC) with subtypes T1, T2, and T3, and fermented carrot-supplemented chapattis (FCSC) with subtypes T4, T5, and T6. The variants were provided to 11 professionally trained sensory panelists for organoleptic evaluation. The chapattis subtype with the best organoleptic properties together with the WWFC were then given randomly to a group of 30 persons with T2D respectively to see how their blood sugar levels were affected over a period of 4 weeks.Results The panelist adjudged RCSC (T2) and FCSC (T5) as the best organoleptically. The randomised control investigation demonstrated that the fasting blood glucose levels for WWFC, RCSC, and FCSC decreased (P&lt;0.05) significantly by 6.42%, 7.24%, and 12.75%, respectively. However, there was no significant different in the fasting blood sugar between the WWFC and RCSC. As for the glycemic load values of WWC, RCSC, and FCSC, which were 21, 14, and 13, respectively, there was no statistically significant difference between RCSC and FCSC, suggesting that both types of chapattis could help T2D patients regulate their blood sugar levels. The most significant changes were consistently shown by the FCSC: 17.50% reduction in random blood sugar (p = 0.03), 21.85% reduction in serum low-density lipoprotein (p = 0.051), 16.67% increase in serum HDL (p = 0.01), 11.09% decrease in serum cholesterol (p = 0.02), and 12.575% reduction in serum triglycerides (p = 0.048).ConclusionsA beneficial dietary intervention for people with T2D may involve mixing fermented carrot powder into regular chapattis. These findings contribute to the growing body of evidence in favour of using natural food-based treatments for the management of diabetes.

Use of waste fermented black carrot powder dried by different methods as a substitute in noodle production

This study delved into various aspects of noodle production, emphasizing the impact of waste fermented black carrot powder (WFBCP) concentration and drying techniques. Higher concentrations of WFBCP increased cooking times, particularly in freeze-dried (FD) samples, resulting in varying water absorption and notable cooking losses. Color variations, influenced by both WFBCP concentration and drying methods, led to generally darker hues in the FD samples. Significant differences in the water content were observed across treatments. Ash content increased significantly with higher WFBCP concentrations, particularly at 40%, indicating the impact of WFBCP on ash formation. Noodle samples exhibited a significant rise in oil content with increasing WFBCP concentration, reaching a peak at 20%. Total Phenolic Content notably increased at higher WFBCP concentrations, peaking at 40%, suggesting potential nutritional benefits. Similarly, antioxidant activity increased significantly with higher WFBCP concentrations, indicating enhanced protection against food oxidation. Total monomeric anthocyanin content surged with increased WFBCP concentration, establishing WFBCP as a noteworthy source of anthocyanins. HPLC analysis revealed elevated levels of phenolic compounds when WFBCP was added to noodles, with FD-WFBCP showing the highest content. Freeze-drying effectively preserved the phenolic compounds, while the protein content remained stable. Sensory analysis, conducted using a 0–10 scale, emphasized the impact of processing methods and WFBCP concentrations on attributes such as color, stickiness, chewing, flavor, and overall rating. This study underscores the importance of precise control over WFBCP concentrations and processing for enhancing noodle attributes. Principal component analysis, explaining 90.8% of the total variation, highlights distinct differences between control and treated samples.

Biological Characteristics of the Mycelium and Optimization of the Culture Medium for Phallus dongsun.

This study aimed to elucidate the influence of various culture medium components, including carbon sources, nitrogen sources, inorganic salts, suspension agents, and temperature, on the mycelial growth characteristics of Phallus dongsun. Employing single-factor experiments and response surface methodology within glass Petri dishes, the research identified that carrot powder, soybean powder, and ZnSO4 notably enhanced the proliferation of aerial mycelium, significantly augmenting the growth rate of P. dongsun mycelium. The resultant mycelium was observed to be dense, robust, and fluffy in texture. In particular, ZnSO4 markedly accelerated the mycelium growth rate. Furthermore, xanthan gum was found to effectively modulate the medium's viscosity, ensuring a stable suspension and facilitating nutrient equilibrium. The optimal cultivation temperature was determined to be 25°C, with mycelial growth ceasing below 5°C and mycelium perishing at temperatures exceeding 35°C. The optimal medium composition was established as follows: wheat starch 5 g/l, carrot powder 5 g/l, soybean powder 7.50 g/l, glucose 10 g/l, ZnSO4 0.71 g/l, NH4Cl 0.68 g/l, xanthan gum 0.5 g/l, and agar 20 g/l. Under these optimized conditions, the mycelium of P. dongsun exhibited a rapid growth rate (1.04 ± 0.14 mm/day), characterized by a thick, dense, and well-developed structure. This investigation provides a theoretical foundation for the conservation, strain selection, and breeding of P. dongsun.

Technology of Enrichment of A2 Dairy Products with Carrot Powder Carotinoids

Topicality. Milk is an available for consumption, popular and nutritious food product, which contains a variety of important macronutrients and biologically active compounds, including carotenoids. Carotenoids contained in food products have low bioavailability, solubility and stability. A high fat content and a unique fat composition of dairy products can be used in order to overcome the problem of low carotenoid bioavailability which is common to fruits and vegetables. Therefore, the usage of fortified dairy products can be a potential means of increasing the supplyof carotenoids to the human body. The aim of the article is to eleborate a technology for enriching A2 dairy products with carrot powder carotenoids. Experimental samples of A2 milk with a mass fraction of fat (3.2%) were produced: control (without additives); sample 1 (enriched with carrot powder in the amount of 10%); sample 2 (enriched with carrot powder in the amount of 20%). The carrot powder was added to milk, thoroughly mixed for 10 minutes, and subjected to homogenization under a pressure of 100-110 MPa, after which it was filtered. The carrot pulp separated during milk filtration, in the amount of 10 and 20% by weight of the product, was used to enrich yogurts. Research methods. Using standard methods, in experimental milk samples organoleptic, physico-chemical indicators were determined according to DSTU EN ISO 1211:2022 (Ukrainian Research and Training Centre for Problems of Standardisation, Certification and Quality, 2023), as well as microbiological indicators were defined according to DSTU 7357:2013 (Ministry of Economic Development of Ukraine, 2014), DSTU 7089:2009 (State Consumer Standard of Ukraine, 2011), and carotenoid content (by chemical method). Additionally, the change in the active acidity of yogurts during their storage was studied by the method of direct potentiometry. Results. It was established that the addition of carrot powder had a positive effect on organoleptic quality indicators of milk, and caused an increase in the protein mass fraction within their composition by 0.03–0.04%. When adding 10% of carrot powder, the concentration of carotenoids increased by 0.163 mg/100 ml, and when adding 20%, then by 0.553 mg/100 ml accordingly. In the case of applying homogenisation under high pressure, and when enriching milk with carrot powder, its microbiological stability was ensured. Enrichment of yogurts with carrot pulp led to a significant increase of dietary fibers content in their composition, and allowed to raise the pH level of the finished product. During the entire storage period, the active acidity of enriched yogurts was within the normal range. Conclusions and discussion. Enrichment of milk with carrot powder and using homogenisation under high pressure leads to an increase in the concentration of carotenoids in milk, which provides almost 5% of the daily needs.

The Impact of Cluster Fig Fruits Powder Addition on Nutritional and Organoleptic Properties of Some Healthy Food Products

Cluster fig, also known as goolar in Hindi, is a medicinal fruit abundant in India, offering a rich source of iron and other essential micronutrients. Wheat, a staple in the Indian diet, is energy-dense and provides valuable carbohydrates and proteins. Pearl Millet, the most commonly grown type of millet, is renowned for its high calorie, vitamin, and mineral content. Mung beans, part of the legume family, are calorie-dense and a great source of protein and polyunsaturated fatty acids. In this study, cluster fig powder, germinated wheat flour, germinated mung bean flour, germinated pearl millet, carrot powder, and beetroot powder were utilized for product development. Two products were developed with three treatments, varying the quantity of ingredients. Sensory and proximate analysis were conducted on the developed products, with each treatment having three different replications to minimize errors during analysis. Based on the sensory evaluation, T1 is considered the best among all treatments, with a moderate ratio of cluster fig contributing to its taste and flavor. The ash content varied across replications, with the control product having the highest ash content of 11.03%, likely due to experimental errors. Treatments T1, T2, and T3 had ash content values of 10.19%, 10.55%, and 10.89%, respectively. Organoleptic evaluation indicated that as the quantity of cluster fig increased, the taste became bitter, leading to decreased acceptability. Proximate analysis revealed that an increase in the quantity of cluster fig resulted in higher iron and zinc content in the products. This study highlights the organoleptic acceptability and nutritive &amp; medicinal properties of cluster fig, providing insights into the appropriate quantities of cluster fig powder and other ingredients for various processed convenience healthy foods. The research emphasizes the use of cluster fig, a readily available fruit in India, which has not been previously utilized in convenience food products.

Bioactive Potential of Carrot-Based Products Enriched with Lactobacillus plantarum.

The primary goal of this study was to generate different kinds of functional products based on carrots that were supplemented with lactic acid bacteria. The fact that carrots (Daucus carota sp.) rank among the most popular vegetables in our country led to the convergence of the research aim. Their abundance of bioactive compounds, primarily polyphenols, flavonoids, and carotenoids, offers numerous health benefits. Among the obtained products, the freeze-dried carrot powder (FDCP) variation presented the highest concentrations of total carotenoids (TCs) and β-carotene (BC) of 26.977 ± 0.13 mg/g DW and 22.075 ± 0.14 mg/g DW, respectively. The amount of total carotenoids and β-carotene significantly increased with the addition of the selected lactic acid bacteria (LAB) for most of the samples. In addition, a slight increase in the antioxidant activity compared with the control sample for the FDCP variant, with the highest value of 91.74%, was observed in these functional food products. The content of polyphenolic compounds varied from 0.044 to 0.091 mg/g DW, while the content of total flavonoids varied from 0.03 to 0.66 mg/g DW. The processing method had an impact on the population of L. plantarum that survived, as indicated by the viability of bacterial cells in all the analyzed products. The chromatographic analysis through UHPLC-MS/MS further confirmed the abundance of the bioactive compounds and their corresponding derivatives by revealing 19 different compounds. The digestibility study indicated that carotenoid compounds from carrots followed a rather controlled release. The carrot-based products enriched with Lactobacillus plantarum can be considered newly functional developed products based on their high content of biologically active compounds with beneficial effects upon the human body. Furthermore, these types of products could represent innovative products for every related industry such as the food, pharmaceutical, and cosmeceutical industries, thus converging a new strategy to improve the health of consumers or patients.

Impact of fibre supplementation on microbiome and resilience in healthy participants: A randomized, placebo-controlled clinical trial

Background and aimsThe gut microbiome exerts important roles in health, e.g., functions in metabolism and immunology. These functions are often exerted via short-chain fatty acid (SCFA) production by gut bacteria. Studies demonstrating causal relationships between interventions targeting the microbiome and clinical outcomes are limited. This study aimed to show a causal relationship between microbiome modulation through fibre intervention and health. Methods and resultsThis randomized, double-blind, cross-over study included 65 healthy subjects, aged 45–70 years, with increased metabolic risk (i.e., body mass index [BMI] 25–30 kg/m2, low to moderate daily dietary fibre intake, <30g/day). Subjects took daily a fibre mixture of Acacia gum and carrot powder or placebo for 12 weeks, with an 8-week wash-out period. Faecal samples for measurement of SCFAs and microbiome analysis were collected every 4 weeks. Before and after each intervention period subjects underwent the mixed-meal PhenFlex challenge Test (PFT). Health effects were expressed as resilience to the stressors of the PFT and as fasting metabolic and inflammatory state. The fibre mixture exerted microbiome modulation, with an increase in β-diversity (p < 0.001). α-diversity was lower during fibre mixture intake compared to placebo after 4, 8 and 12 weeks (p = 0.002; p = 0.012; p = 0.031). There was no effect observed on faecal SCFA concentrations, nor on any of the primary clinical outcomes (Inflammatory resilience: p = 0.605, Metabolic resilience: p = 0.485). ConclusionAlthough the intervention exerted effects on gut microbiome composition, no effects on SCFA production, on resilience or fasting metabolic and inflammatory state were observed in this cohort. Registration number Clinicaltrials.govNCT04829396.

Elevated temperature extraction of β-carotene from freeze-dried carrot powder into sunflower oil: Extraction kinetics and thermal stability.

β-Carotene, a precursor of vitamin A, can alleviate the deficiency of this vitamin prevalent worldwide. Earlier research studies have addressed the extraction of β-carotene at relatively low temperatures (up to 70°C) due to its perceived instability at higher temperatures, as a result of which extraction rates recorded are relatively low. This study models the net rate of β-carotene extraction by considering both extraction and degradation kinetics. The model developed, which accounts for degradation occurring in solid and extract phases, has been experimentally validated for the extraction of β-carotene from freeze-dried carrot powder into sunflower oil over a range of temperatures 90-150°C. This study also gives insights into the application of sunflower oil as a carrier for β-carotene during cooking and food processing, by monitoring and modeling the thermal degradation and isomerization of β-carotene at temperatures up to 220°C. The modeling of extraction kinetics shows that it is possible to achieve viable extraction rates by employing temperatures in the range (90-150°C) for relatively short times (<5min). The degradation kinetics shows that almost 75% of the β-carotene can survive heating at 180°C for 10min-indicating the possibility of using β-carotene enriched edible oils for frying. This study also reports on the formation of three isomers of β-carotene identified using HPLC: trans-, 9-cis, and 13-cis. The reaction network model developed in this study was able to account for the transient variation of the concentration of all three isomers. PRACTICAL APPLICATION: β-Carotene is a precursor of vitamin A and its consumption can potentially alleviate the deficiency of this vitamin prevalent worldwide. This study validates a model for the extraction of β-carotene in sunflower oil, which takes into account extraction as well as degradation occurring during extraction, so that a rational method is available for the design of efficient extractors for this purpose. This paper also establishes the thermal stability of β-carotene under frying conditions by quantifying its thermal degradation as well as isomerization.

Effects of dietary fibre source and content and extrusion conditions on the physicochemical composition and physical quality of fibre‐enriched lentil snacks

SummaryThe growing recognition of the health benefits associated with dietary fibre and the deficit in its daily intake are propelling the food industry to develop a variety of fibre‐enriched products including puffed snacks. Incorporating rich sources of fibre into pulse‐based foods can supplement the insufficient daily dietary fibre intake. To produce fibre‐enriched puffed pulse snacks and ready‐to‐eat breakfast cereals, three different fibre sources, namely carrot powder (CP), wheat bran (WB) and red lentil hulls (LH), were added to red lentil (RL) flour at 0%, 10% and 20% levels (w/w) and extruded at three extrusion moisture contents (MC), i.e., 18%, 20% and 22% (db). Incorporation of all three fibres into RL flour significantly (P ≤ 0.05) increased the total and insoluble dietary fibre contents and hardness and decreased the expansion index, brightness and crispiness of extrudates. Scanning electron microscopy images revealed that the fibre‐enriched extrudates had thicker cell walls with smaller cells when qualitatively compared to RL extrudates with no fibre addition. CP containing extrudates had significantly (P ≤ 0.05) higher soluble dietary fibre (SDF) content compared to extrudates containing WB and LH. WB containing extrudates were significantly (P ≤ 0.05) harder and less expanded than CP and LH containing extrudates at the same MC. The increase in fibre incorporation level increased the hardness of CP and WB containing extrudates but did not affect LH containing extrudates. Fibre incorporation level also increased the colour differences between RL extrudates with and without fibre enrichment. Increasing MC significantly (P ≤ 0.05) increased the SDF and hardness and decreased the expansion index of extrudates. These results can potentially pave the way for the production of fibre‐enriched pulse‐based puffed products, namely, snacks and ready‐to‐eat breakfast cereals, that are texturally and structurally appealing to consumers.

Development of technological solutions to increase the biological value of gluten-free bread

The industry of gluten-free bakery products has not been studied properly, so this topic is gaining popularity among scientists. The subject of the research was the development of recipes for gluten-free flour mixtures. To improve the taste characteristics of the product and increase the biological value, it was decided to introduce plant raw materials non-traditional for bread. Chia seeds and carrot powder were chosen as additives. The goal of the research was to develop recipes for gluten-free flour mixtures. The research was carried out in several stages: 1. determination of the component composition of the gluten-free mixture recipe and production of prototypes; 2. analysis of organoleptic indicators; 3. carrying out physical and chemical studies of dough and finished products. To carry out the analysis instrumental and visual research methods were used. During the experiment three samples of bread were obtained from different types of gluten-free flour (No. 1 – green buckwheat; No. 2 amaranth flour; No. 3 – gram flour) in combination with rice flour, carrot powder and chia seeds. The control sample was bread made from rice flour, potato and corn starch. The rate of dietary fiber supplementation was calculated on the basis of the recommended daily intake. Thus, 2.8 g of dietary fiber was added with carrots, and 4.4 g of dietary fiber with chia seeds. According to all the studies carried out, sample No. 3 from gram flour turned out to be the best. The research results can be used in the baking industry to expand the range of bakery products. A mixture for making gluten-free bread can be a very useful product, especially for those categories of the population who have a need for such products. Also, given that for the majority of the population bread is a commodity of everyday demand, the production of such mixtures will be in great demand.

РАЗРАБОТКА РЫБОРАСТИТЕЛЬНЫХ ПИЩЕКОНЦЕНТРАТОВ (СНЕКОВ) ИЗ РЫБ ВНУТРЕННИХ ВОДОЕМОВ

Introduction. Concentrated food products are in great demand for their lengthy storage time, high nutritional value and full readiness for consumption. The range of existing concentrated food products derived from fish is limited by the presence of intermuscular bones, high rates of fish oil oxidization, and by pronounced specific taste and flavor, usually undesirable by the consumers. These reasons contribute to the relevance of the exploration of possible ways to improve marketability and consumer appeal of minced fish and the development of recipes for the mixed fish- and plant-based concentrated food products derived from it. This work is aimed at the development of formulations for the mixed fish- and plant-based concentrated food products (snacks) derived from preprocessed fish mince with improved organoleptic and rheological properties. Over the course of this research, established and currently accepted research methods have been used. Results. It has been found out that rinsing fish mince with 1 % aqueous solution (aqueous system) based on mustard powder allows for the improvement of its texture, color, flavor and taste. With the use of mathematical modeling, optimal proportions (by weight) for the main components of the mixed fish- and plant-based concentrated food products have been identified: fish mince (70–85 %), wheat bran (9–10 %), carrot powder (5 %), and beet powder (10 %). Conclusion. It has been established that 1 % aqueous solution (aqueous system) of mustard powder can be used as a rinsing solution for fish mince to ensure its fresh flavor with pleasant mustard undertones, as well as vastly improved color and texture. The optimized weight percentages of the main components (fish mince, wheat bran, powdered carrot and beet) made it possible to obtain concentrated food products with attractive organoleptic properties.

Effect of replacing wheat flour with red carrot powder on the physicochemical and sensory properties of cake

The study aimed to produce cake by replacing wheat flour with red carrot powder by 0, 15, 20, and 25% and studying its effect on physicochemical and sensory properties. The chemical estimates showed that the moisture content decreased as the replacement percentage increase compared to the control sample. The protein, fat, and ash percentage increased with increasing percentages of red carrot powder. A study of some physical characteristics of the treatments with different ratios of substitution showed that the higher the substitution ratios for red carrot powder, the greater the weight and volume of the cake product. In contrast, the specific volume of the cake was the highest value for the cake without red carrot powder added. As for the height of the cake, it was the highest value at the replacement ratios of 20 and 25%, represented by treatment T2 and T3, respectively, compared to the control sample. The sensory evaluation of the cake product showed that the color characteristic recorded the highest value in treatment T1. The odor recipe was distinguished upon treatment T2 and T3. The taste characteristic of the cake product differed significantly from the rest of the treatments T0 and T1, and the texture recipe recorded the highest value on transaction T3. The results of the pH values indicated a gradual decrease in the pH values during storage for all treatments of the cake product, compared to the control sample, and the occurrence of damage and spoilage of the product after 30 days. The results of the water activity values of the cake models manufactured for different proportions during different storage periods 1, 10, 20, and 30 days showed a gradual decrease with the increase of time.

Unlocking the potential of carrot pomace: Enzymatic and impact-disintegrator-activator processing for elevated beta-carotene concentration in carrot powder

Backgrounds: Carrot pomace is a by-product of the juice industry, which quickly spoils due to its high moisture content and is usually considered waste. However, it is a valuable product containing a significant amount of bioactive compounds, particularly carotenoids.Context and purpose of this study:In this study, we aimed to develop a technology for obtaining carrot powder from carrot pomace with an increased availability of beta-carotene. The unique aspect of the technology involved the use of enzymatic and impact-disintegration-activation processing (IDAP) of the raw material to enhance the release of beta-carotene from plant cells.Objective of this study:To achieve the goal, we have set objectives to compare various dosages of enzyme preparation and to evaluate devices for grinding carrots that can be used to make powder. At all stages, it was necessary to measure the amount of beta-carotene in the samples.Results: It has been found that the yield of carotenoids from carrot pomace is 185% higher compared to whole carrots. Moreover, the application of enzymatic and impact-disintegration-activation processing significantly increases the carotenoid yield in the powder by 17 times compared to carrots (200% in terms of dry matter). This remarkable result was achieved through the described processing method and the selection of the enzyme preparation. Additionally, the mechanoactivation obtained by using the Desi-15 disintegrator played a crucial role. It was also observed that the use of impact-disintegration-activation processing for further grinding of dried carrots can increase the beta-carotene yield by 8 times. Conclusions: The carrot pomace was processed, resulting in a fine-dispersed carrot powder that shows promising applications in the food or agricultural industries.Keywords: Carrot pomace, beta-carotene, impact-disintegrator-activator processing (IDAP), enzymatic processing, pectolytic enzyme preparations

In almost all countries of the world, there is a rapid development of areas related to the production of products of increased nutritional value. Pasta is one of the most popular food products and is included in the list of everyday products that are in great demand among the population, in this regard, there is an excellent opportunity to reduce the lack of vitamins in a large part of the population by adding non-traditional raw materials to pasta. The authors set a goal to investigate the effect of vegetable powders on the quality indicators of pasta, for which an original recipe for pasta with the addition of carrot powder was developed. The enterprise JSC "Kostanay flour mill" was chosen as the base for the study. Determination of organoleptic quality indicators of pasta was carried out according to generally accepted methods, on a five-point scale. Physical and chemical indicators were determined according to the method set forth in the regulatory and technical documentation; two qualitative indicators were taken as a basis: the mass fraction of moisture and acidity. Thus, a recipe for a new type of pasta enriched with vegetable powder was developed and the quality indicators of the finished product were evaluated

Rapid and non-destructive detection of organic carrot powder adulteration using spectroscopic techniques

Additives used for food adulteration are difficult to detect because they have properties similar to the samples they are added to. Organic foods have more positive effects on food safety compared to their conventional counterparts. Therefore, it is important to assess the detectability of additives that resemble the main ingredient and are used for adulteration purposes in organic powdered products. In this study, the feasibility of using a chromameter and near infrared spectroscopy (NIRS) to discriminate adulterated organic black carrot powders, which were dried by hot air (HA) and intermittent microwave (IMW), was investigated. Principal component analysis (PCA) and partial least squares regression (PLSR) were used for data analysis. The best PLSR models for estimating the adulteration level (%) were obtained using NIRS data (R2val=0.98, RMSEP=4.9%) for samples dried by HA. Furthermore, results showed that temperature or power levels applied during drying affected the efficiency of adulteration determination in samples.
