Innovative prospects for the creation of biologically active complexes based on a polysaccharide matrix

The possibility of combining complexly soluble arabinogalactan polysaccharides with chitosan polysaccharides to increase the absorption of biologically active substances and compounds characterized by low bioavailability is being considered. Included in the biologically active biopolymer matrix are chitosan succinate, succinic anhydrite, arabinogalactan and dihydroquercetin, respectively, in quantities, wt. %: 3–5.0; 2.0–4.0; 15.0–20.0 and 3.5 can serve as a targeted carrier for the delivery of diagnostic and therapeutic agents, including enzymes, nucleic acids, vitamins, hormones, etc. to certain cells, in particular, hepatocytes (liver parenchyma cells). The high membranotropic properties of arabinogalactan isolated from larch have been established, which allows its use to increase the absorption in the gastrointestinal tract of other functionally active ingredients with low bioavailability. The mechanism of this action is associated with the formation of a binding complex between arabinogalactan and the delivered agent, which has the ability to interact with the asialoglycoprotein cell receptor. Studies have been carried out on the possibility of combining arabinogalactan polysaccharides with chitosan polysaccharides to obtain a biopolymer matrix, which includes chitosan succinate, succinic anhydride and arabinogalactan containing dihydroquercetin not covalently bound to it. Along with the above properties, the effectiveness of using arabinogalactan is shown using the example of its use to improve the technological and functional characteristics of broiler chicken meat with PSE traits. The addition of arabinogalactan to the recipe composition of minced meat during the production of sausages, in an amount of 0.5% of the main raw material, increased the moisture-binding capacity by 5% while reducing losses during heat treatment by 6%. There was an improvement in peroxide and acid numbers during storage, which ensures inhibition of oxidative processes and prevents spoilage of finished products.

Development of biomaterials based on chitosan-gelatin nanofibers encapsulated with Ziziphora clinopodioides essential oil and Heracleum persicum extract for extending the shelf-life of vacuum-cooked beef sausages

The aims of the current study were to encapsulate Ziziphora clinopodioides essential oil (ZEO, 0%, 0.15%, and 0.25%) and Heracleum persicum extract (HPE, 0%, 0.25%, and 0.5%) into the chitosan-gelatin (CH-GE) nanofibers through the electrospinning process to improve the shelf-life of vacuum-cooked beef sausages through 70 days of refrigerated storage. Scanning electron microscopy indicated that all nanofibers appeared thin, well-defined, smooth, and possessed uniform thread-like fibers without any beads or nodule formations. The Fourier transform infrared spectroscopy study confirmed the molecular interaction between encapsulated compounds and CH-GE nanofibers. The X-ray diffraction analysis of nanofibers showed an increase in crystallinity after incorporating ZEO and HPE into the polymer. Treated sausages with CH-GE-ZEO 0.25%-HPE 0.25% and CH-GE-ZEO 0.25%-HPE 0.5% showed significantly lower microbial population and lipid oxidation than the control group during the experiment period (P < 0.05). Sausages formulated with designated CH-GE nanofibers had better microbial, chemical, and sensory properties compared to sausages treated with pure ZEO/HPE during refrigerated storage. The findings also showed that treated sausages with CH-GE-ZEO 0.25%-HPE 0.5% had the highest color, odor, texture, and overall acceptability after 70 days of refrigerated storage conditions. Therefore, this treatment could be applicable for the prolonged storage conditions during cooked beef sausage production.

В статье отражены результаты качественной оценки полукопченой колбасы из утиного мяса, выработанной с применением комплексной пищевой добавки. Полученная полукопченая колбаса была произведена в условиях СХПК «Каусар» Лаишевского района Республики Татарстан. В выполненной работе для выработки полукопченой колбасы была использована пищевая добавка, содержащая экстракты пряностей (черный и белый перец, кардамон и чеснок), соль (8 %), коптильный ароматизатор, усилитель вкуса и аромата (E 621), регуляторы кислотности, изоаскорбиновую кислоту и пирофосфат (E 450) в разной дозировке. В ходе эксперимента было выявлено различие физико-химических и органолептических характеристик опытных образцов №1 (с дозировкой пищевой добавки 0,97 %) и №2 (с дозировкой пищевой добавки 1,26 %). Показатели по массовой доле поваренной соли и массовой доле влаги образца №2 на 1 % выше, чем у образца №1. Усовершенствование классической технологии производства полукопченой колбасы позволило получить наилучшие результаты по органолептическим и физико-химическим показателям при содержании пищевой добавки в полукопченой колбасе в количестве 0,97 %. Опытные образцы №1 и №2 имели запах с ароматом пряностей, свойственный полукопченому мясу птицы. Образец №2 отличался слабовыраженным привкусом остроты по сравнению с образцом №1, который имел умеренно соленый вкус без постороннего привкуса. The article reflects the results of a qualitative assessment of half-smoked duck meat sausage produced using a complex food additive. The resulting semi-smoked sausage was produced in the conditions of the SHPK «Kausar» of the Laishevsky district of the Republic of Tatarstan. In the work performed, a food additive containing spice extracts (black and white pepper, cardamom and garlic), salt (8 %), smoke flavor, flavor enhancer (E 621), acidity regulators, isoascorbic acid and pyrophosphate was used to produce semi-smoked sausage. (E 450) in different dosages. During the experiment, a difference was revealed in the physicochemical and organoleptic characteristics of prototypes No. 1 (with a dosage of a food additive of 0.97 %) and No. 2 (with a dosage of a food additive of 1.26 %). The indicators for the mass fraction of table salt and the mass fraction of moisture of sample No. 2 are 1 % higher than those of sample No. 1. The improvement of the classical technology for the production of semi-smoked sausage made it possible to obtain the best results in terms of organoleptic and physico-chemical parameters with the content of the food additive in semi-smoked sausage in the amount of 0.97 %. Experimental samples No. 1 and No. 2 had a smell with the aroma of spices, characteristic of semi-smoked poultry meat. Sample No. 2 was distinguished by a slightly pronounced aftertaste of sharpness compared to sample No. 1, which had a moderately salty taste without foreign aftertaste.

In vitro antioxidative activity of Fritillaria cirrhosa D. Don straw ethanolic extract and its effect on lipid, protein oxidation, and quality of Chinese-style sausage.

Fritillaria cirrhosa D. Don, which can be used for medicine and food, contains a variety of chemicals including polyphenols, alkaloids, terpenoid, and others that have beneficial biological properties like antihypertension, bacteriostasis, and anti-inflammatory. The ethanolic extract of Fritillaria straw was obtained for this study using ultrasonic-aided extraction, and the amounts of total phenols and total flavonoids were 26.56±1.36mgGAE/gdw and 18.75±0.80mgRE/gdw, respectively. Ultra-performance liquid chromatography-quadrupole time-of-flight-mass spectrometry technology was utilized to identify 50 major chemicals in the Fritillaria straw extract (FSE). Meanwhile, the antioxidative activities of FSE were evaluated by 2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and Ferric reducing antioxidant power assays in vitro, which pointed out the antioxidative potential of FSE. Additionally, 0.1%, 0.5%, and 1% of FSE and 0.02% butylated hydroxyanisole (BHA)+butylated hydroxytoluene (BHT) (1:1) were separately added to Chinese-style sausage to study their effects on the lipid oxidation, protein oxidation, and quality of the sausage at different storage times. The study found that the effect of adding 1% FSE on carbonyl content, total volatile basic nitrogen, and TVC of sausage could achieve the effect of the 0.02% BHA+BHT (1:1) group on the 35th day, and the thiobarbituric acid reactive substances value and peroxide value of sausage were significantly lower than the control group. Therefore, as one of the candidates to replace synthetic antioxidants, the FSE can be used in the production of Chinese sausages, which has a positive effect on improving the product's quality and extending the shelf life. PRACTICAL APPLICATION: The antioxidative activities of 50 main compounds were identified after the ethanolic extraction of Fritillaria straw. This Fritillaria straw extract was added to Chinese sausage, effectively inhibiting the oxidation of lipids and proteins as well as the decomposition of proteins. Obviously, the Fritillaria straw extract, one of the choices to replace synthetic antioxidants, may be useful for future meat processing, because of its positive impact on the product's quality and shelf life.

Improving the aroma profile of inoculated fermented sausages by constructing a synthetic core microbial community.

Commercial starter cultures play a critical role in the industrial production of fermented sausages. However, commercial starter cultures could not reproduce the metabolic actions of diverse microorganisms and the aroma profile of the traditional spontaneously fermented sausages. Identifying the core microbial community in spontaneously fermented sausages will facilitate the construction of a synthetic microbial community for reproducing metabolic actions and flavor compounds in spontaneously fermented sausages. This study aimed to reveal the core microbial community of spontaneously fermented sausages based on their relative abundance, flavor-producing ability, and co-occurrence performance. We identified five promising genera to construct the synthetic core microbial community, these were Lactobacillus, Staphylococcus, Macrococcus, Streptococcus, and Pediococcus. Sausages inoculated with a synthetic core microbial community presented higher quality of aroma profile than the fermented sausages inoculated with a commercial starter culture. Some important volatile flavor compounds of spontaneously fermented sausage, such as (-)-β-pinene, β-caryophyllene, 3-methyl-1-butanol, α-terpineol, ethyl 2-methylpropanoate, and ethyl 3-methylbutanoate which are associated with floral, fruity, sweet, and fresh aromas, were also detected in fermented sausage inoculated with synthetic microbial community. This indicated that the synthetic core microbial community efficiently reproduced flavor metabolism. Overall, this study provides a practical strategy to design a synthetic microbial community applicable to different scientific fields.

Flaxseed Gum/Arabic Gum/Tween 80-Based Oleogel as a Fat Substitute Applied in Emulsified Sausage: Physicochemical Properties, Sensory Attributes and Nutritional Quality.

In the present study, flaxseed gum (FG), Arabic gum (GA) and Tween 80 were used to prepare oleogels through an emulsion-templated method, and the obtained oleogels were designed for the partial substitution of pork fat in emulsified sausage. An increment in FG concentrations enhanced the viscoelasticity of emulsions, which resulted in the improved stability of emulsion systems, with smaller droplet sizes. In addition, increased FG concentrations contributed to higher mechanical strength, denser network structure and lower oil loss of oleogels. As a fat substitute, the prepared oleogels improved the textural properties and nutritional quality of emulsified sausages. With the increase in the substitution level of oleogels, the hardness and chewiness of the emulsified sausage increased, and the cooking loss decreased. Meanwhile, the reformulation with oleogels decreased the saturated fat from 57.04 g/100 g lipid to 12.05 g/100 g lipid, while increasing the ratio of omega-6 to omega-3 essential fatty acids from 0.10 to 0.39. The obtained results demonstrated that the flaxseed gum/Arabic gum/Tween 80-based oleogels had huge potential to successfully replace pork fat in emulsified sausage products.

Development of a mathematical model for predicting the quality of semi-smoked sausages made from second-grade beef

The article is devoted to the development of a mathematical model for predicting the quality of semi-smoked sausages from beef of the 2nd grade. The use of meat raw materials below 1st grade in the production of high quality sausages due to enrichment with new natural ingredients represents the relevance of the research. The use of enzymes and buckwheat flour in the production of meat products contributes to the improvement of the quality characteristics of the initial meat raw material, increasing the nutritional and biological value of finished products. The results showed that the addition of the enzyme "Protepsin" intensifies the processes of hydrolysis of proteins of connective tissues of beef, increases the moisture-binding ability of model minced meat. It was found that in model minced meat with the use of enzyme in the amount of pH reaches the optimum value in a shorter time. At addition of buckwheat flour the optimum value of moisture-binding capacity is established. The article shows that increasing the amount of buckwheat flour in the formulation of model minced meat more than 6 % leads to an increase in moisture-binding capacity, but at the same time organoleptic characteristics deteriorate significantly. The results obtained during the experiment showed that the enzyme «Protepsin» can be recommended to improve the functional and technological indicators of minced meat and ready semi-smoked sausages and accelerate the maturation process of raw materials. In this paper the object of the study is model minced beef minced meat of 2 grades, enzyme «Protepsin», buckwheat flour.

Determination of pathogens and contamination indicators in fresh pork sausages in the state of São Paulo

The highest cost of beef and chicken meat justifies higher consumption of fresh sausage products, especially linguiça, due to their easy preparation and affordability for consumers, making necessary an evaluation of sanitary hygienic conditions of these products. The objective was to investigate the presence of pathogens such as Salmonella spp., coagulase-positive Staphylococcus, thermotolerant coliforms, Escherichia coli and Campylobacter spp. in artisanal and inspected fresh pork sausages. It was found that 12% (6/50) of the artisanal sausage samples were contaminated with Salmonella spp., 58% (29/50) presented coagulase-positive Staphylococcus levels above the acceptable limits for consumption and 76% (38/50) presented thermotolerant coliform levels above the acceptable limits. In sausage samples produced under inspected conditions, 6% (3/50) were contaminated with Salmonella spp., 24% (12/50) presented thermotolerant coliform levels above the acceptable limits, 2% (1/50) presented enteropathogenic E. coli. None samples showed coagulase-positive Staphylococcus counts above the limits, or presence of Campylobacter spp. Sensitizing traders and consumers about the importance of inspection service in food of animal origin is urgent for a sanitary acceptable production, since foodborne diseases continue to be a public health problem.

Enrichment of meat products with natural bioprotectors and antioxidants

In the course of scientific research the chemical composition, physico-chemical and antioxidant properties of local grape and secondary raw materials of winemaking industry were studied, the technology of sausage production with the addition of grape extract of high nutritional value was substantiated and developed. Information on the antioxidant activity of grape raw materials growing in the territory of the Republic of Bashkortostan has been obtained. The presence of biologically active substances with antioxidant and antioxidant properties in the grape extract is a promising factor for the introduction of the extract in food products, including meat products, to enrich them with antioxidants. Analyzing the results of the study, we can conclude that the use of 3% grape squeeze extract will enrich meat products with a sufficient amount of antioxidants of natural plant origin. In the course of research it was found that the extract from grape squeeze has a rich dark blue color due to the high content of anthocyanins, which can affect the organoleptic characteristics of the finished meat product, in connection with that the color characteristics of the minced meat samples were analyzed. An important indicator in our scientific research was the preservation of antioxidants in the process of preparation of the extract and introduction into the minced meat. In this regard, the degree of preservation of calculated and actual total content of antioxidants in different objects was further studied. The technology of obtaining new types of food products - sausages, based on the use of grape extracts has been scientifically substantiated. It has been established that within the framework of the modern theory of positive nutrition it is more reasonable to add grape squeeze extract instead of fatty meat raw materials. This allows to enrich sausage products not only with mineral substances, organic and polyunsaturated fatty acids, vitamins, amino acids, pectin substances, but also to obtain biologically valuable meat products based on secondary grape raw materials.

Improved Organoleptic Properties in Cooked Sausages through a Mutton-Poultry Blend: An Analytical Study

This study investigates the implications of utilizing a combination of mutton and poultry meat for cooked sausage production, with an emphasis on understanding changes in chemical composition and textural properties. Utilizing a systematic approach, four experimental variants were developed, progressively incorporating up to 30% poultry meat as a replacement for mutton. A comprehensive chemical analysis revealed an increase in the water-binding capacity, a notable decrease in fat content, and a slight increase in ash content (P<0.05 for both changes). In contrast, textural assessment showed no significant variations across the samples. The blending of mutton and poultry meat demonstrated an enhancement of organoleptic properties, inclusive of flavor, aroma, juiciness, and tenderness of the final product, without compromising the textural characteristics. The results of this study underline the potential benefits of integrating mutton and poultry in cooked sausage production, suggesting a novel pathway to create a nutritious, tasty, and high-quality product. The findings possess implications for the meat industry, providing scientific backing for the inclusion of diverse meats for an optimized product formulation.

Selection of Debaryomyces hansenii isolates to improve quality of dry fermented sausage

ABSTRACT The objective of this experiment was to select D. hansenii isolates that are stable in dry fermented sausage (DFS) production and can positively affect the quality. D. hansenii isolates were examined for production of biogenic amines, β-glucuronidase, β-glucosidase, proteolytic, and lipolytic enzymatic activities. The acid and salt tolerance of D. hansenii isolates were also examined. DFS inoculated with selected D. hansenii isolates were analyzed for microorganisms, weight loss, Aw, and pH. DFS was also subjected to analyses of color, texture profile, reducing sugar, volatile basic nitrogen (VBN), lipid oxidation, and free fatty acid. Twenty-two D. hansenii isolates were isolated. None of these D. hansenii isolates produced biogenic amines, and all strains were negative for β-glucuronidase and β-glucosidase activities. After examining these strains for proteolysis, lipolysis, and salt and acid tolerance, D. hansenii isolates SMFM2021-C14, SMFM2021-S8, and SMFM2021-SL3 were selected to be used in DFS. During the processing of DFS, the groups treated with D. hansenii isolate SMFM2021-S8 or SMFM2021-SL3 showed lower (p < .05) hardness values of DFS. The sample treated with D. hansenii SMFM2021-S8 showed lower (p < .05) VBN and lipid oxidation contents than the others. The ratio of ω-6/ω-3 was lower (p < .05) in D. hansenii SMFM2021-SL3 treated group than in the other treatments. These results indicate that D. hansenii isolates SMFM2021-S8 and SMFM2021-SL3 might be useful in producing DFS to improve its quality.

Analysis of Pork in Beef Sausages Using LC-Orbitrap HRMS Untargeted Metabolomics Combined with Chemometrics for Halal Authentication Study.

Beef sausage (BS) is one of the most favored meat products due to its nutrition and good taste. However, for economic purposes, BS is often adulterated with pork by unethical players. Pork consumption is strictly prohibited for religions including Islam and Judaism. Therefore, advanced detection methods are highly required to warrant the halal authenticity of BS. This research aimed to develop a liquid chromatography-high-resolution mass spectrometry (LC-HRMS) method to determine the halal authenticity of BS using an untargeted metabolomics approach. LC-HRMS was capable of detecting various metabolites in BS and BS containing pork. The presence of pork in BS could be differentiated using principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA) with high accuracy. PLS-DA perfectly classified authentic BS and BS containing pork in all concentration levels of pork with R2X = (0.821), R2Y(= 0.984), and Q2 = (0.795). The level of pork in BS was successfully predicted through partial least squares (PLS) and orthogonal PLS (OPLS) chemometrics. Both models gave high R2 (>0.99) actual and predicted values as well as few errors, indicating good accuracy and precision. Identification of discriminating metabolites' potential as biomarker candidates through variable importance for projections (VIP) value revealed metabolites of 2-arachidonyl-sn-glycero-3-phosphoethanolamine, 3-hydroxyoctanoylcarnitine, 8Z,11Z,14Z-eicosatrienoic acid, D-(+)-galactose, oleamide, 3-hydroxyhexadecanoylcarnitine, arachidonic acid, and α-eleostearic acid as good indicators to detect pork. It can be concluded that LC-HRMS metabolomics combined with PCA, PLS-DA, PLS, and OPLS was successfully used to detect pork adulteration in beef sausages. The results imply that LC-HRMS untargeted metabolomics in combination with chemometrics is a promising alternative as an analytical technique to detect pork in sausage products. Further analysis of larger samples is required to warrant the reproducibility.

Optimization of Ultrasound-Assisted Extraction of Dietary Fiber from Yellow Dragon Fruit Peels and Its Application in Low-Fat Alpaca-Based Sausages.

The main objective of this study was to optimize the extraction of dietary fiber (insoluble dietary fiber and soluble dietary fiber) and degree of esterification from yellow dragon fruit peels using ultrasound-assisted extraction. Additionally, the study aimed to investigate the potential application of this fiber as a fat replacement in alpaca-based sausages. The optimization process for extracting dietary fiber and degree of esterification involved considering various factors, including the liquid-to-solid ratio, pause time, and total ultrasound application time. A Box-Behnken design consisting of 15 treatments was employed to determine the optimal levels for ultrasound-assisted extraction. The optimized conditions were found to be a liquid-to-solid ratio = 30 mL/g, pause time = 1 s, and total ultrasound application time = 60 min, which resulted in the highest values of insoluble dietary fiber (61.3%), soluble dietary fiber (10.8%), and the lowest value of degree of esterification (39.7%). The predicted values were validated against experimental data and showed no significant differences (p > 0.05). Furthermore, a completely randomized design was utilized to assess the effect of dietary fiber on replacing fat content during the production of alpaca-based sausages. The findings revealed that up to 78% of the fat content could be successfully replaced by soluble dietary fiber obtained from yellow dragon fruit peels when compared to high-fat sausages. Additionally, experimental sausages using soluble dietary fiber showed similar (p > 0.05) quality characteristics, such as hardness (24.2 N), chewiness (11.8 N), springiness (0.900), cohesiveness (0.543), redness (a* = 17.4), and chroma values (20.0), as low-fat commercial sausages.

Instrumental Color Measurements Have Relationships to Fat Smearing in Fresh Sausage.

Fat smearing, or poor fat particle definition, impacts the visual quality of sausage. However, objective methods of assessing fat smearing have not been identified. Therefore, the objective of this experiment was to determine the relationship between fat smearing and instrumental color analysis for fresh sausages to create a standard method for using instrumental color in fat smearing analysis. Meat blocks of pork (PK), beef (BF), and a mixture of pork and beef (P/B) were formed and processed at three different temperatures to create varying degrees of fat smearing. The average fat smearing score of each sausage was used to determine if a relationship existed with instrumental color measurements (CIE L*, a*, b*, and reflectance percentage at 580 nm and 630 nm) and color calculations. A correlation was observed for L* (R = -0.704) and the reflectance at 580 nm (R = -0.775) to PK fat smearing (p < 0.05). In P/B sausage, both reflectances at ratios between 630 nm and 580 nm were correlated to P/B fat smearing. No measurement or calculation was correlated with BF fat smearing (p > 0.05). Therefore, it is possible to use instrumental color analysis for the evaluation of fat smearing in pork and pork/beef blended sausage products, but not in beef sausage products.

Plant based meat alternative, from cradle to company-gate: A case study uncovering the environmental impact of the Swedish pea protein value chain

Dry-fractioned pea protein concentrate can be moulded into meat-analogue products, and understanding the environmental impact and hot spots of this expanding industry segment could pave the road to broader adoption of these protein sources. Hence, this research measures the environmental performance of a green pea protein supply chain in southern Sweden that processes pea protein concentrate into pea protein sausages. A cradle-to-factory-gate life-cycle assessment was performed. 1 kg of pea protein concentrate at 46% and 1 kg of pea protein sausages were chosen as functional units, while ReCiPe 2016 v1.1 Midpoint E was utilized to calculate 18 impact categories. Economic allocation was applied to pea protein processing, and mass allocation to sausage production, using 2021/22 data from Swedish companies. For 1 kg of pea protein concentrate of 46%, cultivation contributes to 41–99% of the total impact considering all 18 impact categories, while processing 1–59%. The climate impact was 1.91 kg CO2eq/kg pea protein concentrate (1.54 from the cultivation step and 0.37 from the processing step). For 1 kg of pea protein sausages, cultivation and sausage production contributed together between 32% and 78% to the total impacts. The climate impact was 1.0 kg CO2eq/kg sausage. Comparing the climate impacts of sausage ingredients, rapeseed oil and spices contributed significantly. For the sausage production stage, electricity and natural gas contributed the most. The results for climate impact are in the same range as for similar plant-based products, although the range reported in literature is wide. Green pea cultivation, sausage production and ingredients contributed all significantly. The results highlight the need to address the choice of ingredients when formulating the final product. The choice of allocation method had a significant impact on the results. Mass allocation resulted in 6 times lower impacts for the pea protein concentrate compared to economic allocation.

Application of beekeeping products in the technology of raw smoked sausages

The safety of fermented sausage products is due to the elimination of a number of risks of biological origin, mainly of a microbiological nature. One of the most promising directions for the development of barrier technologies is the use of starter cultures and the biologically active substances produced by them in the production of fermented meat products. The research aims to study the influence of starter cultures and honey on a complex of physico-chemical, structuralmechanical, organoleptic indicators and nutritional value of raw smoked sausages. The article presents changes in the physical and chemical parameters of raw smoked sausages when using starter cultures in combination with different types of honey. When performing the work, 4 types of honey were used: from sunflower, phacelia, honeydew honey and from medicinal herbs. At the first stage of research, the proportion of honey application and the type of starter crops were selected. The next stage of the study was to determine the impact of the starter cultures included in the product BIOSTART PLUS 50 (lactic acid bacteria Lactobacillus Sake and yeasts Debaryomyces Hansenii) and honey on moisture loss during fermentation of raw smoked sausages, physicochemical parameters of finished products. Determination of moisture content in samples was carried out by drying in a drying cabinet at a temperature of 103±2°C. Conducted studies prove that the use of the product BIOSTART PLUS 50 (lactic acid bacteria Lactobacillus Sakei and yeasts Debaryomyces Hansenii) and honey allows shortening the ripening and drying technological process. A comparative analysis of manufactured raw-smoked sausages in terms of nutritional value makes it possible to state that manufactured raw-smoked sausages with the addition of honey meet the requirements of the standard. The results of the set of studies carried out in this work showed that the use of a composition of lactic acid bacteria and yeast with the use of honey as a source of carbohydrates will allow intensifying the technological process and improve the quality of finished products

A comparative Hygienic Evaluation of Balance of Lipid Components in the Diet of Medical University Students

INTRODUCTION: A balanced diet provides the optimal level of metabolism and is one of key modifiable factors of the primary prophylaxis of chronic non-infectious diseases. Excess of the common fat in the diet is the most common alimentary imbalance in nutrition of the population.&#x0D; AIM: A comparative characteristics of the level of the alimentary intake and of the main alimentary sources of lipid components in medical university students.&#x0D; MATERIALS AND METHODS: For quantification of entry of lipid components, the method of triple 24-hour reproduction was used. The data on actual nutrition were acquired and analyzed using a specialized questionnaire developed for the given study.&#x0D; RESULTS: A comparative analysis of levels of intake of the common fat, saturated and polyunsaturated fatty acids did not identify any statistically significant differences in women and men in both groups the main sources of the common fat and saturated fatty acids were hard cheese, milk chocolate, sausage products, chicken eggs, butter and mayonnaise. The main contribution to the required level of polyunsaturated fatty acids, irrespective of gender, were made by sunflower oil, fish, mayonnaise, nuts, seeds, pizza and olive oil.&#x0D; CONCLUSION: The level of intake of common fat with the diet exceeds the physiological demand in 95.3% of women and 94.8% of men. A share of saturated fatty acids made more than 10% of the energy value in 92% of female respondents and in 94% of male respondents, which is associated with the excessive quantity of the sources of hidden fat in the diet of students of the two comparison groups, such as hard cheese, milk chocolate and sausage products. In 45% of students, owing to the presence of oils, fish, mayonnaise and nuts in their diet, the level of entry of polyunsaturated fatty acids met the physiological demand.

Assessment of function-technological and rheological parameters of consistency stabilisers for dairy protein-fat systems for the production of semi-smoked sausages

During the past few years, the world community has faced a number of problems related to the delivery and storage of milk and milk products. In particular, the situation provoked by quarantine restrictions in various countries of the world forces to look for solutions regarding the use of non-traditional raw materials for the production of classic or similar food products. As a result, it is quite promising to use dairy products with extended shelf life, in particular, dry milk concentrates as the main protein carriers for the production of stable protein-fat systems. The use of dry milk proteins makes it possible to manufacture restored structural products that can be used as an alternative to classic ones. Therefore, the object of research is food components of various origins, in particular food modified starches, food fibers and their modifications, hydrocolloids. Characteristic indicators of viscosity with increasing shear stress were determined for 5 % solutions of modified starches of various types after brewing at a temperature of 80 °C. It was found that when the shear stress increases to a value of 200 Pa, there is a significant decrease in viscosity, which generally characterizes them as structural systems. The functional and technological indicators of wheat (VF-200), bamboo (BAF-200) food fibers (fiber length 200 microns) and carboxyl methyl cellulose (CMC) were studied. Increased functional and technological capabilities of CMC compared to dietary fibers were revealed. The kinetics of swelling of dietary fibers and CMC were studied, while the period of maximum intensification of the process, which is between 5 and 15 minutes, was determined. The maximum value of the swelling coefficient is characteristic for CMC 4.4±0.04, for wheat fiber 4.01±0.06, for bamboo fiber 3.81±0.05. Using the method of mathematical and statistical processing of experimental data, optimization of concentration and technological modes was carried out to achieve maximum hydration and strength of iota-carrageenan gel. It was determined that at a concentration of 1 % during brewing at 80 °C and a time of 5 min. high enough gel strength can be achieved for optimum consistency in the overall system. The result of the work is a comprehensive study of the functional technological characteristics of food additives that will form the consistency of a structural protein-fat product of the cheese type, which can be used in sausage products as a filler, with the aim of improving the organoleptic, structural-mechanical and nutritional values of the finished products.

Chard powder as natural source of nitrites for fermented dried sausages: physicochemical and microbiological studies

Nitrites are added to sausage products to accelerate ripening, improve color and microbiological indicators. Chard (Beta vulgaris var. cicla) is one of the best natural sources of nitrites, as it contains a lot of nitrates – 1680 mg/kg in a fresh vegetable. However, chard has not been used as a source of nitrites in sausage technology and in cooking it is used only in fresh, boiled or sautéed form. There are no technologies for industrial drying and processing of chard into powder. Chard powder was obtained by microwave vacuum drying and grinding to 200 microns, which was determined by the appropriate sieve size. Five samples of fermented dried sausages were prepared and evaluated during the ripening process: C1 (without nitrite and sodium nitrate), C2 (100 mg/kg sodium nitrite and 100 mg/kg sodium nitrate), M1 (0.5 % chard powder), M2 (1 % chard powder) and M3 (1.5 % chard powder). With the addition of 1.5 % chard powder (Sample M3), the protein content increased by 22.74 %, ash content increased by 41.82 %, and dietary fiber content increased by 93.75 % compared to the control sample C2. Nitrite was formed from chard powder during the ripening process, especially in treatments M2 and M3. After the entire production process of fermented dried sausages for 35 days, nitrates were detected only in sample C2. The yield of fermented dried sausages enriched with chard powder decreased by 15.95 % compared to the control sample C2. Chard powder improved the microbiological parameters of sausage products, especially in sample M3. The content of aerobic mesophilic bacteria increased by 5.84 % and the content of lactic acid bacteria increased by 8.96 % in sample M3 compared to control C2 after 35 days of fermentation and drying, which is related to the activity of the starter. The organoleptic parameters of fermented dried sausages enriched with chard powder for samples M2 and M3 were better in terms of color and texture. The results of the analysis of nutritional value, pH, nitrites and nitrates indicate the effectiveness of adding 1.5 % chard powder (Sample M3) obtained by microwave vacuum drying as a potential source of nitrites in fermented dried sausages.
