Formulation, Standardization and Shelflife Study of Fiber Rich Idli Premix with Ragi Barnyard Millet and Fortified with Dried Papaya Leaves

Abstract

Idli is a traditional fermented food product made from a batter of ground rice (Oryza sativa) and black gram (Phaselous muno) which undergoes lactic acid fermentation via lactobacillus. It is a breakfast food originated from South India. This premix provides a gluten- free, low-glycemic index option compared to traditional idlis, enhancing nutritional intake and tackling health issues such as diabetes. Phytochemical profiling of young leaves of Carica papaya revealed the presence of pharmacologically active phyto compounds, alkaloids, phenolics, flavonoids, and amino acids. The research applied a methodical approach to formulating the product, which included selecting ingredients, preparing them, and blending to achieve the best sensory qualities. This premix also offers a quick and convenient meal solution while maintaining its nutritional value, addressing the preferences of today’s health-focused consumers. The increasing interest in functional foods has prompted the creation of meal options rich in nutrients that promote health and wellness. Conventional idlis are usually prepared with rice, which has a high glycemic index and is low in crucial micronutrients. Substituting rice with ragi and barnyard millet enhances the premix's protein, dietary fiber, and mineral levels, making it more appropriate for people dealing with diabetes, gluten sensitivity, and deficiencies in micronutrients. Trails A, B, and C have been taken, and the sensory panelists have finalized Trail C. Sensory evaluation verifies that the product is well-received in terms of flavour and overall attractiveness. Following the guidelines in the FSSAI Manuals, the contents of moisture, fat, protein, and ash were examined. The Weendes method is used to determine fiber. This research investigates the development and assessment of a nutritious idli premix enhanced with ragi (finger millet), barnyard millet, and dried papaya leaves, aiming to offer a healthier and functional option compared to traditional idli mixes.
