Nutri-cereals are rich sources of starch with immense potential for non-food and food applications. Starch derived from these cereals exists in its native form but can be modified through chemical, physical, and enzymatic techniques to escalate its functional properties. Modification strategies improve attributes such as gelatinization, pasting behavior, solubility, and thermal stability, making starch more suitable for novel utilizations in the pharmaceutical, food, textile, and biodegradable packaging industries. In the food sector, modified nutri-cereal starch plays a crucial role in developing functional foods with improved stability, texture, and nutritional benefits. Additionally, advancements in starch-based biodegradable films and industrial adhesives highlight its sustainability potential. This chapter explores the myriad transformations of nutri-cereal starch, emphasizing its significance in innovation-driven industries..
