Development and quality evaluation of a micronutrient rich traditional Indian product by utilization of locally available food resources

ABSTRACT Malnutrition is a severe matter of concern among various countries due to modern lifestyles, especially the consumption of rapidly processed fast food. In 2018, a WHO and UNICEF study concluded that the SDG objective of eradicating all forms of malnutrition by 2030 was aspirational but unattainable and set targets for malnutrition indicators up to 2030 based on current trends. The present situation demands products rich in micronutrients, meet growth and development requirements, and are readily acceptable. A critical reason for such use of rice flour is its nonallergenic nature. A small proportion of the population is allergic to wheat gluten. Rice is widely used in baking for such wheat-intolerant people, i.e., those suffering from the coeliac disorder. Its nonallergenic property also makes rice one of the first cereals to be used in infant feeding. In this scenario, rice flour is preferred as the foremost choice for required sensory acceptability and a low-cost diet. Food-based approaches are recognised as an essential part of an urgently needed, more comprehensive strategy for improving nutrition by increasing the availability and consumption to combat calcium, iron, phosphorus and other micronutrient deficiencies. The combination of rice flour, beaten rice, banana, jaggery contains a high amount of energy protein with calcium and iron content. Such a combination of foods can enhance the nutritive value of homemade products, which can be beneficial for the malnourished population. The present study was undertaken to develop anarsa by combining banana, jaggery and rice flour using the air frying method. The developed product was evaluated for sensory attributes by a panel of 10 judges on 9 points hedonic rating scale. The calculated nutritive value from Indian Food Composition Tables (2017) showed that the product (100g) was not only had a high level of macronutrients, i.e. energy (3123.6 Kcal), carbohydrate (172.5g), protein (12.24g), fat (4.52g) but also rich in micronutrients like calcium (262.8mg), phosphorus (294.4mg) and iron (6.52mg). The product was packed and stored for 15 days at ambient temperature in an airtight container. At pre-evaluation, all the sensory parameters at the 9-point hedonic rating scale were found to be highly acceptable between 'liked moderately' (rating 8) to 'liked very much. After 15 days of storage, all sensory parameters changed and were lying in-between 'liked slightly' (rating 6) to 'liked moderately' (rating 7). The changes in sensory parameters may be due to the darkening of jaggery and changes in the flavour of the product. Thus, it can be concluded that the development and consumption of novel foods from rice flour in combination with other foods like may banana, jaggery and poppy seeds may provide cost-effective and acceptable options for combating macro and micronutrient deficiencies.

The effect of the use of cassava tuber (Manihot esculenta) and Indigofera zollingeriana leaf flour combination as a source of energy supplemented with citric acid in ration on broiler small intestine characteristics and productivity.

The study aimed to determine the effect of using a combination of cassava tuber (Manihot esculenta) and Indigofera zollingeriana leaf flour as an energy source supplemented with citric acid in the ration on performance, carcass quality, digesta pH, viscosity, and the number of villi in the intestines of broilers. The research design was completely randomized with five treatments and five replications, each containing four broilers. The treatment was a substitution of corn in the ration with a combination of cassava tuber and I. zollingeriana leaf (CIF): without CIF, 5% CIF substitute for corn + 0.2% citric acid, 10% CIF substitute for corn + 0.2% citric acid, 15% CIF corn substitute + 0.2% citric acid, and CIF corn substitute + 0.2% citric acid. Each treatment ration was supplemented with 0.2% citric acid. The variables that were looked at were ration consumption, body weight gain, feed conversion, live weight, percentage of the carcass, percentage of abdominal fat, pH, viscosity, and the number of broiler villi. This study showed that the combination of CIF flour supplemented with 0.2% citric acid had a significant effect (p < 0.05) on body weight gain, ration conversion, live weight, carcass percentage, and the number of villi in broiler intestines. But it did not have a significant effect (p > 0.05) on the amount of feed eaten, the amount of fat in the abdomen, the pH of the digesta, or the thickness of the broilers' blood. The combination of CIF flour at a level of 10% supplemented with 0.2% citric acid can be used as an energy source to replace corn without having a bad effect on production performance, carcass quality, and small intestine characteristics of broilers.

Selenized chickpea sourdoughs for the enrichment of breads

The use of chickpeas sprouted with sodium selenite as ingredient for sourdough bread enrichment is explored. Backslopping was followed to obtain selenium enriched sourdoughs produced with sprouted chickpeas. Afterwards, breads containing 150 or 300 g/kg lyophilized chickpea sourdoughs with or without selenium (SeGCS) were produced. The effects on dough rheology, bread features and nutritional properties with emphasis in Se content were assessed. A positive effect of sprouted chickpea in generation of organic acid during fermentation and an increase of LAB bacteria was observed during sourdough and dough stages. In bread, the increase in the level of sourdough or selenium values were accompanied by a decrease in the volume, crumb resilience, higher density and lower number of gas cells that were less prone to recover after compression. The serving of 85 g of bread (34 g/100 g of moisture) prepared with 300 g/kg of SeGCS sourdough can meet 100% of the recommended daily Se intake (55 μg/day). Moreover, the combination of pulse flours with cereal flours, the use of sprouted flours and sourdough technologies offer new alternatives to generate an array of enriched breads.

The food industry by-products in bread making: single and combined effect of carob pod flour, sugar beet fibers and molasses on dough rheology, quality and food safety.

Obtaining high-quality value-added bread with extended shelf-life by utilizing food industry by-products that would have minimal negative effect on gluten structure while avoiding the usage of synthetic preservatives, was the challenge of this study. For this purpose the influence of the combination of carob pod flour (C, 0-15%), sugar beet fibers (F, 0-10%) and sugar beet molasses (M, 0-6%) on dough rheology and bread quality was investigated. Selected materials were of good microbiological quality, while carob flour and sugar beet fibers were rich in dietary fibers (43.6% and 67.0%, respectively). The presence of high share of dietary fibers (combination of C and F) increased dough resistance to extension up to 2.5 times, while dough extensibility was reduced by 50%. The addition of molasses had less pronounced single effect on dough properties however its impact in combination with fiber-rich materials outweighed the individual effect (an increase of dough resistance at about 55%). Molasses alone and in combination with other ingredients had positive effect on bread quality. Sample M6F5 attained crumb quality score (6.0 of maximum 7.0) higher than in control sample (5.6). High share of C and F reduced loaf volume and crumb quality of bread up to 56% and 50%, respectively and increased hardness 7.5 times. However, carob flour (7.5%) increased polyphenols content and antioxidant capacity 3 and 4 times, respectively. Moreover, carob flour and molasses and their combination showed inhibitory effect on mold mycelia growth and spores formation. Regarding all of the above, C7.5M3F5 was chosen as optimal sample.
