Nutritional and Functional Characterization of Flour from Seeds of Chañar (Geoffroea decorticans) to Promote Its Sustainable Use.

Cereal bars are a nutritional food of sweetened and acceptable flavor and are a source of vitamins, minerals, fibers, proteins and complex carbohydrates. The objective of this work was to study the effect of dietary fiber concentration and sugar in cereal bars made of oats with a high dietary fiber content. In the research, oat flakes, bran and flour from cultivar UPFA 22, selected on the basis of the dietary fiber and b-glucans content, were used. The ingredients were used in amounts defined in laboratory tests. The experiment was carried out using a central composite rotational design applicable to the response surface methodology (RSM), and the effects of the sugar syrup concentration (70, 75 and 80 °Brix) and dietary fiber content in the formulation (12, 16 and 20%) on the chemical composition, calorie value, water activity, microbiology and sensorial characteristics of the cereal bars were evaluated. The results were analyzed by multiple regression and the significant linear, quadratic and interaction terms were used in the second order mathematical model. The results showed that oats can be used as an ingredient when making cereals bars presenting an adequate texture, flavor and appearance. The oats used in the formulation makes cereal bars with high dietary fiber and b-glucan content. The bars present acceptable sensorial properties, similar to the industrialized bars, with higher acceptability when made with average concentration of sugar and high dietary fiber content. The cereal bars present low water activity and are within sanitary specifications and can be stored for 60 days.

ObjectiveEffect of addition of wheat bran (WB) and dried carrot pomace (DCP) on sensory, textural, colour, physico-chemical and nutritional characteristics of chicken sausage were evaluated.MethodsWB and DCP were used as a source of dietary fibre at 3%, 6%, and 9% level individually. Different quality attributes of sausages were estimated. One product from each source with very good sensory acceptability was selected to analyze dietary fibre content and shelf life under refrigerated storage.ResultsSensory acceptability of 3% fibre enriched sausage was comparable with control and a further increase in fibre level resulted in a decrease in sensory acceptability. Fibre enriched sausages were significantly harder and less cohesive than control sausage. Significant increase in gumminess and chewiness was observed at 6% level in WB treated sausages and 9% level in DCP treated sausages. Moisture content decreased significantly in all treated sausages, protein content decreased significantly in DCP-2 and DCP-3 sausages while fat content decreased in all WB and DCP-3 treated sausages in comparison to control. The fibre enriched sausage had significantly higher dietary fibre and lower cholesterol content. Cooking yield and emulsion stability increased in treated sausages and a significant difference was noticed at 6% level in both types of sausages. pH of WB treated sausages was significantly higher and DCP treated sausage significantly lower in comparison to control.ConclusionThe results of present study indicate that fibre enriched chicken sausage with moderate acceptability can be developed by incorporating WB and DCP each up to 9% level. Chicken sausage with very good acceptability, higher dietary fibre content and storability up to 15 days at refrigerated temperature can be developed by incorporating WB and DCP at 6% level each.

This study evaluated the bioconversion of agro-industrial by-products (dry olive leaves, OL; full-fat dry olive pomace, OP; and quinoa husk, QH) by Tenebrio molitor larvae, included at different levels in the substrates. Wheat bran (control diet) was replaced with OL (15, 30, 50%), OP (30, 50, 70, 90%), or QH (15, 30, 50%). Productive performance, dietary and larval nutritional composition, and fatty acid profile were determined. Low to moderate inclusion levels (OL and QH up to 15%, and OP up to 30%) supported larval growth comparable to control diets. These formulations maintained or improved the nutritional composition of the larvae, by increasing protein content and reducing lipid levels. In contrast, high inclusion levels caused nutritional imbalances in the diets, likely due to excessive fibre and low protein (for OL and QH) or high lipid, fiber, ash and low carbohydrate contents (for OP), together with high phenolic contents (for OL and OP), which likely affected feed intake and larval development. Additionally, the dietary fatty acid appeared to influence larval lipid composition. Larvae fed OP tended to accumulate more oleic acid and less linoleic acid. Moreover, high dietary lipid and fiber contents due to OP seemed to increase larval oleic acid content while reducing linoleic acid, whereas carbohydrate-rich diets had the opposite effect. Therefore, olive and quinoa by-products in T. molitor feeding offer a sustainable valorisation strategy offer these side streams, if macronutrient balance is maintained when specific levels of the by-products are used to ensure optimal larval growth and feed efficiency.

Gambang bread is a traditional no-yeast Indonesian bread characterized by its palm sugarlike brown colour, dense texture, and spice taste. Coconut dregs are high in dietary fiber but easy to spoil, so blanching is an effective way to prolong the coconut dregs' shelf life. This study investigated the effects of the blanching method and time on yield, water content, fat content, and dietary fiber content of coconut dregs powder. Moreover, the effects of coconut dregs powder substitution ratio and pectin concentration on the microstructure and physical characteristics of the bread (expansion volume and hardness) were studied. Hot water blanching produced coconut dregs powder with lower yield and fat content, as well as higher moisture and dietary fiber content than steam-blanched coconut dregs powder. Blanching time only affected dietary fiber content. 10 mins of blanching produced coconut dregs powder with higher dietary fiber content than 5 mins of blanching. Hot water blanching treatment for 10 mins was chosen as the best treatment. This treatment produced 43.12±0.64% coconut dregs powder. Moreover, the chemical characteristics of chosen coconut dregs powder were 5.40±0.01% water, 34.10±1.56% fat, 3.73±0.1% protein, 0.45±0.02% ash, 55.53±1.28% carbohydrate, and 73.90±0.02% dietary fiber. Higher substitution of coconut dregs powder increased hardness and decreased the expansion volume of gambang bread. Meanwhile, adding pectin significantly reduced the hardness of gambang bread. The best gambang bread was obtained from 10% substitution coconut dregs powder and 0.5% additional pectin. Bread microstructure showed that substituting coconut dregs disrupted the continuity gluten matrix more than control bread.

Composite flours are used for bakery products to improve the nutritional value and reduce the reliance on wheat importation. The present study was aimed at assessing the effect of supplementing whole wheat flour with acha and red kidney bean flours on the physical properties, proximate composition, mineral and sensory characteristics of biscuits made from the blends. Blend ratios used were 100:00:00 (T1, control sample), 75:25:00 (T2), 75:00:25 (T3) and 50:25:25 (T4) (whole wheat: acha: kidney bean flour). The result showed that all the parameters varied with the composition of flours in the blends. The biscuit weight, diameter, thickness and spread ratio ranged from 16.32 to 19.08g, 4.02 to 4.40cm, 0.69 to 0.78cm and 5.33 to 6.38 respectively. Incorporation of kidney bean flour in the blends led to the reduction in spread ratio of the biscuit. The protein, fat, ash, crude fibre and carbohydrate contents in the biscuits ranged from 11.73 to 15.20%, 16.34 to 17.95%, 1.52%, to 1.73%, 1.65 to 1.80% and 63.36 to 68.70% respectively. Samples T3 and T4 with kidney bean flour incorporation had higher protein, dietary fibre and lower carbohydrate contents than samples T1 and T2 with no kidney bean flour incorporation. The calcium, potassium, magnesium, iron and zinc contents ranged from 36.14 – 45.72mg/100g, 105.40 – 128.72mg/100g, 29.60 – 46.81mg/100g, 3.89 – 5.12mg/100g and 2.01 –3.51mg/100g respectively. Incorporation of kidney bean flour enhanced the calcium, magnesium and iron contents in the biscuits. Sensory mean score values showed that samples T3 and T4 were the most preferred samples in terms of overall acceptability as their values were not significantly (p>0.05) difference from each other. It is evident from the study that acceptable biscuits of improved nutritional value and high dietary fibre content could be produced from whole wheat flour supplemented with acha and kidney beans flours. This will increase the utilization of these locally grown crops and reduce wheat importation into the country. The high fibre biscuit will also possess several health benefits.

Dried and ground brewer's spent grain (BSG) was blended with soft wheat flour at levels of 5–25%. BSG preparations of fine (<212 μm), medium (212–425 μm) and coarse (425–850 μM) particle sizes were used in the production of wire-cut cookies. The protein content decreased and the dietary fibre content (acid detergent fibre, neutral detergent fibre and total dietary fibre) increased, as the particle size of the BSG samples increased. The results indicated that BSG preparations with high dietary fibre content have potential as a source of dietary fibre. The effects of BSG on the quality and dietary fibre content of cookies have been investigated. Total dietary fibre (TDF) contents of the cookies supplemented with different particle size BSG increased significantly (p<0.05) as the addition level increased. Cookies prepared with BSG of medium and coarse particle sizes resulted in better properties in terms of Spread Ratio, Hunter color values and overall sensory score as compared to those made with BSG of fine particle size. Cookies made with medium and coarse particle size BSG gave better cookie properties up to the 15% addition and deteriorated significantly above this level (p<0.05).

Nutritional and antioxidant properties of Geoffroea decorticans, an Argentinean fruit, and derived products (flour, arrope, decoction and hydroalcoholic beverage)

There is interest in the production of gluten‐free foods with high dietary fibre content and low caloric supply. It is well known that gluten‐free foods present a poor matrix due to the absence of gluten, a protein that builds the network which provides the accepted textural characteristics of bakery products and pasta. Moreover, gluten‐free products have a low dietary fibre content due to the use of starch or refined flours. The aim of this study was to evaluate the use of unripe plantain flour (UPF) to prepare gluten‐free cookies with high dietary fibre content. A commercial high dietary fibre ingredient (Hi‐Maize 260®) was used for comparison. The hardness, chemical composition, and starch digestibility of the cookies were assessed. The texture and the proximal composition of both cookies was similar, but the dietary fibre content of the cookie with UPF was 100% higher than that of Hi‐Maize 260®, and the former showed a lower predicted glycaemic index. These results indicated that unripe plantain flour can be used as a substitute for commercial ingredients to produce gluten‐free cookies with high dietary fibre content and a low predicted glycaemic index.

Polyphenols rich fraction from Geoffroea decorticans fruits flour affects key enzymes involved in metabolic syndrome, oxidative stress and inflammatory process

Wolffia globosa (W. globosa) or duckweed is a small aquatic plant with high protein, dietary fiber, and lipid contents that can be combined with food products to develop nutritious snacks as one strategy to mitigate malnutrition. Here, response surface methodology (RSM) with mixture design was used to develop snacks from W. globosa freeze-dried powder (WP). The physical properties, proximate analysis, amino acid profiles, sensory evaluation, phytochemical analysis, antioxidant properties, and genotoxicity (Ames test) of the snacks were evaluated. The optimal W. globosa snack formula was 64% glutinous rice flour, 10% tapioca flour, and 26% WP, giving a highly desirable liking score of 1.00. Addition of WP increased crude protein, essential amino acids, and dietary fiber compared with the control snack by 51%, 147%, and 83%, respectively. According to the Thai recommended daily intakes, the developed W. globosa snack had high protein and dietary fiber. Phytochemical contents and antioxidant activities of the W. globosa snack such as total phenolic contents (TPCs), total flavonoid contents (TFCs), ferric ion reducing antioxidant power (FRAP) activity, and oxygen radical absorbance capacity (ORAC) activity were significantly higher than the control snack. The novel combination of WP with snack product ingredients greatly enhanced nutritional value.

Background: Brown rice has greater mineral content than milled rice. However, due to high dietary fiber and phytic acid content, mineral absorption may be suppressed. Objective: To determine the dietary fiber characteristics and mineral availability from treated and non-treated brown rice. Materials and Methods: Four varieties of cooked brown rice were used in the study and the same treated to extend the shelf-life of brown rice. Freeze-dried samples were analysed for proximate composition, dietary fiber, phytic acid, iron, zinc and calcium content using standard methods. Mineral availability and dietary fiber fermentation were determined in vitro. Results: The dietary fiber content of treated brown rice (11.0±0.6 – 11.7±0.1) was significantly greater than that of non-treated brown rice (5.5±0.5 -6.4±0.2; P<0.05). The mineral content and availability from treated and non-treated brown rice did not differ significantly except for mineral availability. Dietary fiber and phytic acid did not show inhibitory effect on mineral availability from both brown rices. The dietary fiber content from both brown rices was fermentable producing short chain fatty acids with greater amounts of propionate. Conclusion: Treated and non-treated brown rice are good sources of minerals and dietary fiber, found to be fermentable, and did not inhibit mineral availability.

The basis of the state policy of Ukraine in the field of healthy nutrition of the population for the period until 2025 is to preserve and strengthen the health of the population, prevention of diseases caused by poor and unbalanced nutrition. Food products enriched with irreplaceable components, including dietary fibers, have been developed. The article substantiates the use of broiler meat as the main ingredient of the recipe, selects and studies the vegetable supplement of oat bran, which contains dietary fibers. The functional-technological and organoleptic indicators of minced meat models with different amounts of vegetable additives were studied, as a result, the optimal dose of introduction was determined and the formulation of the product made from broiler meat with an increased content of dietary fibers was developed. Optimal modes of heat treatment of the semi-finished product using a steam convection oven and modes of cold treatment of the finished product in "shock" freezing chambers were selected. The thermophysical characteristics of the new product were studied, and the duration of its freezing was calculated using Planck's formula. The technology of production of a functional product from broiler meat is proposed. The developed product is characterized by high organoleptic characteristics, such as juiciness of the product, pleasant smell and taste, uniform consistency, as well as a large yield of the finished product. The product contains dietary fibers, in one portion their amount is 8 g, which contributes to the satisfaction of 40% of the body's daily need for this food substance. The optimal recipe and technology of chicken cutlets with dietary fibers have been scientifically substantiated and developed. The possibility of producing chicken cutlets with a high content of dietary fiber has been theoretically and experimentally substantiated. Based on the analysis of the chemical composition and the study of the content of dietary fibers, functional-technological and organoleptic indicators of six vegetable supplements, the feasibility of introducing the vegetable supplement "Oat bran" into the recipe of chicken cutlets was substantiated. The effectiveness of thermal processing of chicken cutlets with increased dietary fiber content when using a convection oven in the steam + convection mode compared to the traditional method of processing has been proven. The raw materials for the production of the finished product were selected, the recipe was developed, the heat treatment parameters were selected, and the technology of quick-frozen finished product was developed. The developed ready-made poultry dish has an increased nutritional value due to the content of dietary fibers. It is taken into account that dietary fibers should be a mandatory part of the diet. Their total content in one portion is 8 g per 125 g of the finished product, which meets the daily need for this indicator by 40%.
