Characterization of Coffee Silver Skin as Potential Food-Safe Ingredient.

By-products from the coffee industry are produced in large amounts each year. Among other wastes, coffee silver skin (CSS) is highly available and more stable due to its lower content of water. This research aimed to characterize coffee silver skin composition and evidence its potentiality for use as a food-safe ingredient in new formulations. Results showed an average total dietary fiber content of 50% but with a higher ratio for insoluble than soluble fiber. A high content of total phenolic compounds, chlorogenic acid, caffeine, and caffeic acid was found and correlated with the high measured antioxidant capacity. Moreover, minerals (e.g., calcium, magnesium, phosphorous, potassium, copper, iron, manganese) important for human wellbeing were found at a high level in CSS, while toxic minerals (e.g., nickel) were found at low levels. In conclusion, coffee silver skin could have an advantageous role for the recovery of valuable compounds and as a potential food-safe ingredient.

Bioaccessibility and Synthesis of Chronobiotics During In Vitro Gastrointestinal Digestion of Pistachio (Pistacia vera L.) to Mitigate Diseases Linked to Chronodisruption

Abstract Objectives This research aimed to evaluate the in vitro chronobiotic potential of Phyto-melatonin (PTM) during gastrointestinal digestion, its fermentative behavior (phenolic acids and other compounds), and potential production of chronobiotics (short-chain fatty acids or SCFAs production). Methods The chemical and nutraceutical composition of dry roasted and salted pistachios with seed coat (SC) (PN + SC) and without (PN) was evaluated. Both samples were digested under static in vitro simulated physiological conditions comprising oral, gastric, intestinal, and colonic stages. The PTM bioaccessibility during in vitro gastrointestinal digestion and colonic fermentation simulation was quantified. The identification and quantification of SCFAs and other colonic metabolites were conducted using SPME-GC-MS, followed by an untargeted metabolomic analysis. Results PN + SC had significantly (p < 0.05) lower lipids (−7.9) and protein (−1.1), but higher carbohydrate (+8.4) and total dietary fiber (+4.8) content (g/100g) than PN. PN + SC had highest content of total phenols (+42%), total flavonoids (+54%), and PMT (+21%) (p < 0.05) compared to PN. The bioaccessibility was low for both pistachio samples [Oral: 1.92 and 3.41%, PN + SC and PN; gastric: 0.83 and 1.63%; intestinal [60 min]: 1.79 and 2.55; colonic [6 h]: 0.32 and 0.36%). Chemo-informatics and an in silico analysis of PTM suggest that it was absorbed when chewed by the participants. The highest SCFAs were produced at 12 h during in vitro colonic fermentation for both pistachio samples, where PN + SC displayed the highest (p < 0.05) value (51 mmol/L), followed by PN (25.9 mmol/L). SCFAs, derived from bacterial fermentation of dietary fibers, can act as chronobiotics in peripheral clocks. The SCFAs molar ratio remained almost constant for both pistachio samples: butyric > propionic > acetic. Some metabolites with chronobiotic potential (e.g., indole, benzaldehyde, phenolic acids, and aliphatic/aromatic hydrocarbons) were detected, sample-dependent, through the untargeted metabolomics. Conclusions Pistachio's digestion increases the bioaccessibility of PTM and the biosynthesis of colonic metabolites (SCFAs, among others), all with chronobiotic potential to mitigate diseases linked to chronodisruption. Funding Sources The funding received by CONACyT/FOPES is appreciated.

Enriched Turkish noodles (Erişte) with stabilized wheat germ: Chemical, nutritional and cooking properties

In this study, different stabilization processes (autoclave, dry heating, microwave, infrared and ultraviolet-C) were applied to wheat germ, and its optimum usage ratio (0, 5, 10, 15 and 20%) in Turkish noodle (Erişte) production was investigated. Some chemical and nutritional (protein, in vitro protein digestibility (IVPD), total phenolic content (TPC), phytic acid, total dietary fiber (TDF), minerals and HCL-extractable minerals and tocopherol contents) attributes, color values and cooking properties of noodle were determined. IVPD values of noodle samples changed with stabilization methods. Protein, TPC, TDF and phytic acid content of noodle increased as the wheat germ ratio increased in the noodle formulation. The highest amount of TPC was obtained from the infrared and ultraviolet-C stabilization. The stabilization method and wheat germ ratio had a significant effect on mineral, HCl-extractable mineral, α-, β- and γ-tocopherol contents and color values of the noodles. The highest α-, β- and γ-tocopherol contents in noodle samples were obtained with autoclave and ultraviolet-C stabilization methods and high wheat germ ratio. Cooking properties were only affected by the wheat germ ratio. As a result increasing stabilized wheat germ ratio improved the nutritional properties of noodle and the highest enrichment was obtained at 20% stabilized wheat germ ratio.

Ultrasound-treated lupin (Lupinus albus L.) flour: Protein- and fiber-rich ingredient to improve physical and textural quality of bread with a reduced glycemic index

In this study, lupin (Lupinus albus L.) flours (0, 10, 15 and 20%) debittered by ultrasound application and traditional method, and resistant starch type 4 (RS4) (0, 5 and 10%) were used in bread production to improve nutritional quality. The effect of ultrasound application on physical, textural and chemical properties of bread enriched with lupin flour and RS4 was investigated. Experiments were conducted at (2 × 4 × 3)×2 factorial design. Ultrasound application presented higher volume, specific volume and lower weight, firmness, hardness and chewiness values in bread compared to the traditional method. Besides, ultrasound had no adverse effect on chemical properties of bread. While the addition of lupin flour decreased volume and specific volume values, increased ash, fat, protein, total dietary fiber, Ca, Cu, Fe, Mg, Mn, P and Zn contents of bread. The bread prepared with 5% RS4 revealed statistically similar volume and specific volume values to bread prepared without RS4 (P > 0.05). Compared to white bread, the use of lupin flour and RS4 in bread formulation significantly (P < 0.05) decreased in vitro glycemic index. These results obtained in this study may provide useful information in the food industry to improve quality of protein- and fiber-rich bread by ultrasound application.

Use of Grape Peels By-Product for Wheat Pasta Manufacturing.

Grape peels (GP) use in pasta formulation represents an economic and eco-friendly way to create value-added products with multiple nutritional benefits. This study aimed to evaluate the effect of the GP by-product on common wheat flour (Triticum aestivum), dough and pasta properties in order to achieve the optimal level that can be incorporated. Response surface methodology (RSM) was performed taking into account the influence of GP level on flour viscosity, dough cohesiveness and complex modulus, pasta color, fracturability, chewiness, cooking loss, total polyphenols, dietary fibers and resistant starch amounts. The result show that 4.62% GP can be added to wheat flour to obtain higher total polyphenols, resistant starch and dietary fiber contents with minimum negative effects on pasta quality. Flour viscosity, dough cohesiveness, complex modulus and pasta fracturability of the optimal sample were higher compared to the control, while chewiness was lower. Proteins’ secondary structures were influenced by GP addition, while starch was not affected. Smooth starch grains embedded in a compact protein structure containing GP fiber was observed. These results show that GP can be successfully incorporated in wheat pasta, offering nutritional benefits by their antioxidants and fiber contents, without many negative effects on the final product’s properties.

Finger millet (Ragi) as an essential dietary supplement with key health benefits: A review

The world geography has so many millet crop producer and India serves as one of the key producers of the millets. Finger millets, a type of small-sized millets, requires larger area of cultivation for growing the crop. Finger millet is considered as a special food supplement because of its high nutritional contents in comparison to other important cereals, namely barley, rye etc. It mainly consists of minerals, dietary fiber and important amino acids. In different parts of our country, especially in South India, the rural population use finger millet (Eleusine coracana), popularly known as ragi, as their principal food. Ragi, among all cereals, contains greater calcium level along with antioxidants and phytochemicals. The finger millet grain possesses a high content of total dietary fiber among other cereal grains that is extremely beneficial in controlling blood glucose level in diabetic patients. Besides, it is also beneficial to patients suffering with cardiovascular disease, cancer and other cognitive diseases. Ragi can be processed through different processing methods to be used as a food supplement attractive in appearance, taste, flavor and consistency. However, despite of its beneficial effects, it is limited in use in the localities, where it is produced. There exists great opportunity for processing finger millet into several functional foods to be used by mass population of our country.

In this study, some chemical, physical and sensory properties of biscuits prepared with various substitution ratios (0, 6, 12 and 18%) of pomegranate peel were determined. To this end, pomegranate peel substitution did not cause a significant alteration in the protein, fat and ash contents of the biscuits. Results show that the antioxidant activity (from 5.06 μmol TE/100g to 288.38 μmol TE/100g), total phenolic content (from 56.49 mg GAE/100g to 1108.35 mg GAE/100g), soluble, insoluble and total dietary fiber contents (from 1.93% to 9.31%) of the biscuits increased significantly by increase of the substitution ratio of pomegranate peel powder (PPP) in the formulation. Hardness decreased significantly with PPP addition in biscuits. It was observed a decrease in L and b color values and an increase in a values of biscuits by increase in the ratio of pomegranate peel substitution. The PPP added samples revealed bigger air cells compared to the control samples in the internal SEM micrographs. In sensory analyses, no significant differences in sensory parameters except taste and overall acceptance of biscuits were observed. Moreover, the panelists confirmed that they felt a more sour and bitter taste in biscuits prepared with 18% pomegranate peel powder and it was considered to be the reason of the decrease in sensory scores. Therefore, it is advised not to exceed 12% pomegranate peel powder substitution in biscuits.

Potential Application of Resistant Starch Sorghum in Gluten-Free Pasta: Nutritional, Structural and Sensory Evaluations.

Gluten-free (GF) pasta samples containing rice flour replaced with 0, 5, 10, 15 g/100 g (w/w) of a resistant starch ingredient from annealed sorghum starch (annRS) were formulated. The highest total dietary fiber and RS contents (p < 0.05) were measured in uncooked pasta with 15 g/100 g of annRS addition (15-annRS). After cooking, the 15-annRS pasta was characterized by an RS content of 5.8 g/100 g dry matter, confirming the thermal resistance of annRS. The use of annRS positively influenced the optimal cooking time, the cooking loss, the firmness, and the stickiness of the cooked samples, with not remarkably change in color after cooking. The starch hydrolysis index values decreased as the level of annRS increased. Despite a significant decrease in the overall sensory with increasing levels of annRS, all samples were characterized by a value > 5, which is considered the limit of acceptability. The use of annRS in GF pasta up to 15 g/100 g can contribute to creating GF products with high total dietary fiber content, slowly digestible starch properties, and without drastically compromising the sensory attributes.

Hulled wheat species are often used as whole grains in processing, and have been attracting attention in the last 20 years in the food industry. Whole wheat flour of hulled wheat can be used in the food industry for value addition. This study was conducted to evaluate the kernel quality and chemical composition of the whole grain flour of hulled wheats as a preliminary approach to use these species for value addition. The experimental design was separate, randomized complete block designs for einkorn, emmer, and spelt, with four field replicates. According to the results, significant differences (p < 0.05) were observed in kernel quality traits, such as test weight, 1000 kernel weight, and kernel hardness, compared to hard red spring wheat. The results of the chemical composition revealed that hulled wheats were characterized by significantly lower (p < 0.05) protein and higher (p < 0.05) crude fat contents compared to whole wheat flour of hard red spring wheat. Among hulled wheats, total dietary fiber content was highest in emmer, followed by einkorn and spelt. In conclusion, the whole wheat flour of einkorn, emmer, and spelt used in this study differ from hard red spring wheat in their kernel quality and chemical composition.

Effect of selected Rwandan wheat varieties on the physicochemical characteristics of whole wheat flour

The present study aimed to evaluate the effect of the wheat varieties newly introduced in Rwanda on the physicochemical characteristics of their whole wheat grains in order to know their potentials for processing. Gihundo wheat grain variety had the highest values for extraction yield (99.20 %), contents of ash (1.47 %) and total dietary fiber (15.97 %), water absorption capacity (89.00 %), dough development time (7.62 min) and brightness (84.67 %). For the same physicochemical characteristics, whole flour from Nyaruka wheat variety showed the lowest values for extraction yield (96.20%), water absorption capacity (80.00 %), dough development time (6.33 min) and brightness (80.33), while whole flour from Reberaho wheat variety exhibited the lowest values for the contents of ash (0.98 %) and total dietary fiber (12.44 %). The protein content ranged between 10.00 % and 10.85 % for whole flours from all wheat varieties. The results showed that whole flour from Gihundo wheat grain variety exhibited high values for most of the physicochemical characteristics determined in comparison to the other three varieties. It is important to select grains or flour from these wheat varieties newly introduced in Rwanda based on the individual cultivar because their derivative products could have a more desired quality.

Hemp seed (Cannabis sativa L.) enriched pasta: Physicochemical properties and quality evaluation.

Hemp seed (Cannabis sativa L.) contain large amounts of nutrients, e.g. protein, dietary fiber, minerals, and unsaturated fatty acids, which make them a good fortifying component in food production. The aim of the present study was to determine the effect of hemp addition on the physicochemical properties, cooking quality, texture parameters and sensory properties of durum wheat pasta. The samples were fortified with 5–40% of commercially available hemp flour or 2.5–10% of hemp cake obtained from hemp seed oil pressing. Our study showed that the addition of hemp seed raw materials led to an increase in the protein, total dietary fiber (TDF), ash and fat content in the pasta samples. Due to its lower granulation and higher nutritional value, hemp flour was found to be a better raw material for the fortification of pasta than hemp cake. Pasta enriched with hemp flour at the level of 30–40% contains 19.53–28.87% d.m. of protein and 17.02–21.49% d.m. of TDF and according to the EU, a definition can be described as a high-protein and high-fiber products. All enriched pasta samples were also characterized by safe Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) content, and their sensory properties were accepted by consumers.

Characteristics of functional brown rice prepared by parboiling and microwave drying

Brown rice (BR) is well known for its functional properties; however, it is considered unsuitable for consumption in modern diet owing to its hard texture, low digestibility, and high lipid peroxidation. In this study, we investigated the physicochemical properties, and cooking and storage characteristics of functional BR prepared by parboiling (100°C, 15 min) and microwave drying (100 kW, 8 rpm, 91°C, 40 min) processes. These processes significantly increased resistant starch (RS) content by 1.5-fold and total dietary fiber (TDF) content by 1.8-fold; Parboiling and microwave drying processes increased the umami taste by 10% using electronic tongue and decreased the hardness by 10% using texture analyzer, respectively. Additionally, irrespective of the storage duration, these processes remarkably decreased acidity and bacterial counts in the parboiled BR group compared to that in the BR group. Presumably, higher RS and TDF contents, enhanced umami taste, and longer shelf-life of BR would help patients with obesity and diabetes, and industries developing relevant high-value food products.

Proximate composition, fatty acid profile, vitamin and mineral content of selected banana varieties grown in Sri Lanka

Nearly 30 varieties of banana (Musa spp.) are grown in Sri Lanka while it is the most produced and traded fruit in fresh form in the world. In the present study, five banana varieties commonly grown in Sri Lanka were evaluated for their nutritional composition. Fruits were collected using stratified random sampling design from all agro-climatic zones, sorted and cleaned. Composite samples were prepared by oven drying a portion of the sample at 45 °C while the rest was freeze-dried. Proximate composition, fatty acid profile and vitamin composition were determined using standard procedures and presented on fresh weight basis. Total carbohydrate, protein and dietary fibre contents of studied banana varieties were 13.46–26.46, 0.14−0.2 and 1.97–2.49 %, respectively. Major fatty acids observed in Musa spp. were palmitic, linoleic, α-linolenic, oleic, stearic, palmitoleic and myristic acids. Vitamin A and E contents were higher than other fat-soluble vitamins. Among studied banana varieties, the nutritional significance of Puwalu was upheld by the highest quantities of fat-soluble vitamins and polyunsaturated fatty acids while the nutritional significance of Kolikuttu was upheld by the highest quantities of protein, dietary fibre, thiamine and riboflavin. Ambul kesel was observed to contain the highest vitamin C content among studied banana varieties.

Physicochemical and Nutritional Properties of Nixtamalized Quality Protein Maize Flour and its Potential as Substitute in Philippine Salt Bread

Nixtamalization is an ancient method of processing corn that is said to enhance the nutritional value of maize by improving protein quality, increasing calcium and niacin bioavailability, and reducing phytic acid levels, thus increasing iron digestibility and biovailability. The main objective of this study was to determine the effect of different nixtamalization processes on the physicochemical and nutritional properties of quality protein maize (QPM) flour and evaluate its potential and acceptability as a flour substitute in Philippine salt bread baking, determined through sensory analysis. Three processes of nixtamalization were employed, namely, traditional, classic, and ecological. Nixtamalized QPM flours, combined with wheat flour in 30:70 ratio, were used in the product development and sensory evaluation of Philippine salt bread. Results revealed that nixtamalization contributed significantly in the pH, color, and particle size of nixtamalized QPM flours. There was a significant increase (P ≤0.05) in the moisture, crude protein, crude fiber, crude ash, calcium, iron, niacin, lysine, tryptophan, total starch, amylose, amylopectin, resistant starch, and soluble fiber contents and a significant decrease in the crude fat, nitrogen-free extract (NFE), phytate, and insoluble fiber contents of QPM flours after nixtamalization. No significant difference was found in the zinc and total dietary fiber contents among the samples. The Philippine salt bread produced using nixtamalized QPM flours had a high overall acceptability based on two-step sensory analysis. QPM is greatly improved by the ancient technology of nixtamalization and nixtamalized QPM flour showed desirable contributions in terms of the nutritional value and sensory attributes of Philippine salt bread when used as a flour substitute or blend.

Non Starch Polysaccharides (Dietary Fibre) of Bio-Fortified Pearl Millet Varieties as Influenced by Malting

The investigation was carried out to assess the effect of malting on non starch polysaccharides i.e. dietary fibre contents of bio-fortified pearl millet varieties (HC-20 and Dhanshakti). It was found that the crude fibre content of malted flours of both the varieties increased significantly (10.0 to 23.07 and 7.74 to 10.96 % respectively in HC-20, and Dhanshakti) compared to unprocessed pearl millet flour. However, a significant reduction in total dietary fibre content of malted flours was observed and this decrease ranged from 3.88 to 4.81 % in HC-20 and from 6.89 to 8.11 % in Dhanshakti variety. The insoluble dietary fibre content of malted flours was also significantly lower than that of unprocessed flours. As a result of malting, soluble dietary fibre content decreased from 12.58 to 18.54 % (HC-20) and 17.36 to 22.22 % (Dhanshakti) compared to unprocessed flour. All types of processed and unprocessed HC-20 flours contained significantly higher amounts of soluble dietary fibre compared to Dhanshakti variety. The crude fibre and dietary fibre of Dhanshakti variety flour was significantly higher than that of HC-20.

Nutritional, physical and sensory characteristics of gluten-free biscuits incorporated with a novel resistant starch ingredient

Gluten-free (GF) biscuits were prepared by replacing part of a GF flour mix (GFM) with 0, 15, 30 and 45 g/100 g (total flour) with a novel resistant starch-rich ingredient obtained from annealed white sorghum starch (RSWS). The chemical composition, physical characteristics, in vitro starch digestion and sensory evaluation of biscuits were considered. The chemical composition of samples was influenced by the addition of the RSWS. The highest total dietary fibre and RS contents (p < 0.05) were measured in 45-RSWS biscuits. The starch hydrolysis index values decreased when the level of RSWS increased in the composite. With regard to quality parameters, the use of RSWS influenced the hardness of the biscuits, and the highest value obtained for 45-RSWS. Some of the selected sensory attributes, along with the overall acceptability score, were negatively influenced by the RSWS addition, even if all remained above the limit of acceptability. The use of RSWS in GF biscuit formulation can contribute towards the creation of food products likely having slowly digestible starch properties, and this can be achieved without drastically compromising on the quality and sensory attributes.

Influence of Addition of Different Levels of Amaranth Grain Flour on Chapatti

Amaranth grains were used in the present investigation. Amaranth grains were washed grains were spread over filter paper sheet and dried completely. After drying, the grains were ground in an electric grinder to fine powder and supplemented at 20, 40, percent and 60 per cent level in the preparation of chapatti. The chapatti prepared by using wheat flour served as control. The organoleptic evaluations showed that all chapatti prepared incorporating amaranth flour were acceptable. The nutritional analysis revealed that the protein content of control chapatti was 12.42 per cent which increased significantly up to 18.23 per cent with incorporation of amaranth grain flour. The crude fibre and ash content in chapatti incorporated with amaranth flour had increased significantly as compared to control chapatti. Total dietary fibre content ranged from 11.13 to 22.06 per cent in supplemented chapatti whereas control chapatti contained 4.80 per cent total dietary fibre. The results of the study indicated that calcium content ranged from 112.44 to 222.70 mg/100 g in supplemented chapatti, whereas control chapatti had 55.59 mg/100 g calcium. The addition of the amaranth flour to chapatti improved iron, zinc and potassium content significantly.
