Dietary Fiber from Soybean (Glycine max) Husk as Fat and Phosphate Replacer in Frankfurter Sausage: Effect on the Nutritional, Physicochemical and Nutraceutical Quality.

The objective of the present study was to evaluate the effect of dietary fiber from soybean (glycine max) husk as fat and phosphate replacer on the nutritional, physicochemical, and nutraceutical quality of Frankfurter sausage. A traditional formulation was used for the pork-based sausage and three treatments were established: control treatment (CT), sausage without SHDF; treatment 1 (T1), sausage and 1% SHDF; treatment 2 (T2), sausage and 1.5% SHDF. T2 showed the best nutritional contribution of the treatments, significantly favoring a lower content of fat and sodium, thus increasing the contribution of dietary fiber and calcium. A positive effect of SHDF on the water-holding capacity of the treatments was also observed. In addition, T2 remained stable during storage, while T1 and CT showed significantly reduced water-holding capacities of approximately 5%; this was in turn linked to hardness, as it was observed that on day 7 of storage, 27% less force was required to deform the T2 sausages. Regarding color, no significant difference was observed with the addition of SHDF to the product. The results suggest that the dietary fiber extracted from soybean husks has potential for application in food and can be used as an ingredient to improve the functional and nutritional quality of Frankfurter sausages by reducing the content of fat and phosphates.

Analysis by UPLC-DAD-ESI-MS of Phenolic Compounds and HPLC-DAD-Based Determination of Carotenoids in Noni ( Morinda citrifolia L.) Bagasse.

Noni bagasse is usually wasted after the noni juice extraction process. The purpose of this study was to investigate the phytochemical composition of noni bagasse (with and without seeds) obtained after a 1 week period of a short-term juice drip-extraction process from over-ripe noni fruit. Totals of free phenolics, flavonoids, condensed tannins, carotenoids, and most of the minerals were higher in bagasse without seeds (NSB) than in bagasse with seeds (WSB), whereas bound phenolics and total and insoluble dietary fiber were higher in WSB than in NSB. ß-Carotene and lutein, quantified by HPLC-DAD, were higher in both bagasse than in juice. A total of 16 phenolic compounds and 2 iridoids were determined by UPLC-DAD-ESI-MS. Among them, procyanidin B-type dimer, caffeoylquinic-acid-hexoside, and quercetin-hexose-deoxyhexose have not been previously reported in noni bagasse, noni juice, or noni fruit. Isorhamnetin-3- O-rutinoside was the most abundant compound in both bagasses. In conclusion, both bagasses are potential sources of phytochemical compounds for the food and pharmaceutical industries.

Dietary Fiber from Chickpea (Cicer arietinum) and Soybean (Glycine max) Husk Byproducts as Baking Additives: Functional and Nutritional Properties.

Dietary fiber extracted from soybean and chickpea husks was used in the formulation of white bread. Treatments at different concentrations of dietary fiber (DF): bread + 0.15%, 0.3%, 1.5%, 2% soybean dietary fiber (SDF); bread + 0.15%, 0.3%, 1.5%, 2% chickpea dietary fiber (CDF), and a control treatment (Bread 0% DF) were used initially. However, the treatments that showed the greatest improvement effects were: bread + 2% SDF and bread + 2% CDF. The functionality and the nutritional contribution in the treatments were evaluated during four days of storage. The weight loss on the third day of storage was 30% higher in the control treatment than the products with 2% SDF and 2% CDF, while for the evaluation of firmness, the control obtained a hardness of 86 N, and treatments with 2% SDF and 2% CDF 60 N and 45 N, respectively. The presence of phenolic compounds and their antioxidant activity was evident, mainly in the 2% SDF treatment, which had a total phenolic content of 1036, while in the Bread 0% DF it was 232 mgEAC/kg. The antioxidant activity for 2% SDF by DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (3-ethyl-benzothiazoline-6-sulfonic acid), and FRAP (ferric reducing antioxidant power) was 1096, 2567, and 1800 µmolTE/kg, respectively. Dietary fiber addition favored the reduction of weight loss and firmness of white bread during storage. In addition, color was not affected and the content calcium, phenolics, as well as antioxidant capacity were slightly improved.

Composición nutricional, compuestos fenólicos y capacidad antioxidante de cascarilla de garbanzo (Cicer arietinum) / Nutritional composition, phenolic compounds and antioxidant capacity of chickpea (Cicer arietinum) husk

La composición química, minerales, azúcares neutros, compuestos fenólicos y capacidad antioxidante fueron analizados en la cascarilla de garbanzo. La cascarilla de garbanzo presentó 72% de fibra dietaria, del cual el 24.4% fue celulosa. Los compuestos fenólicos y actividad antioxidante de de la cascarilla de garbanzo fueron evidentes, predominando los taninos condensados totales con 13.28 mgEC/g, donde la fracción soluble fue mayor respecto a la fracción ligada. El contenido de proteína y grasa fue de 4.5 y 0.4%. En conclusión, la cascarilla de garbanzo tiene propiedades nutricionales y funcionales que pueden ser consideradas en el diseño de nuevos productos alimenticios para mejorar la salud de los consumidores(AU)

The chemical composition, minerals, neutral sugars, phenolic compounds and antioxidant capacity were analyzed in the chickpea husk. Chickpea husk presented 72% of dietary fiber of which 24.4% was cellulose. The content of phenolic compounds and antioxidant capacity of chickpea husk was evident, predominating condensed tannins with a total content of 13.28 mgECat/g, of which soluble fraction was the higher than bound fraction. The content of protein and fat was 4.5 and 0.4 %, respectively. In conclusion, chickpea husk has nutritional and functional properties that can be considered in the design of new food products to improve the health of consumers(AU)
