Quality Evaluation of Millet Based Nutribars

Abstract

Multi millet nutribars are planned to serve as a healthy snack that is packed with energy as well as essential nutrients. The study was carried out to evaluate the quality of millet based nutribars during the storage period of 6 months. The study was carried out in College of Community Science, ANGRAU, Lam, Guntur in the year 2022-2023. In this study, four millet based nutribars were prepared in the combinations of dates, nuts, seeds and oats. Rheological properties (Texture analysis), Physico-chemical properties (water activity, peroxide value, free fatty acid value and total soluble solids), Microbial analysis (Total plate count, Yeast, Mold and E.coli count), Sensory evaluation (colour, appearance, texture, taste, flavour and overall acceptability) at regular intervals during storage and Nutrient analysis (proximates, minerals and chemical composition) were evaluated in four millet based nutribars. The products were organoleptically evaluated using 9 points hedonic rating scale by a panel of trained judge. Among four nutribars, Millets-Seeds nutribar has high overall acceptability followed by oats, nuts and dates nutribar. Prepared multi millet nutribars can be stored for two months. These millet nutribars are ideal for vulnerable groups as a snack.
