The rising awareness about low glycemic load, gluten-related disorders and increasing demand for health-conscious food options have paved the way for innovative gluten-free alternatives. Traditional Indian snacks, such as khakhra, offer a valuable base for nutritional enhancement and dietary diversification. This review focuses on the summarizing various pieces of literature regarding development of nutrient enriched or fortified, low glycemic load, and gluten-free khakhra using different functional ingredients. The article also explores the potential utilization of three functional ingredients: foxnut (Euryale ferox), water chestnut flour (Trapa natans), and flaxseed powder (Linum usitatissimum) to develop gluten-free khakhra. These underutilized, nutrient-dense ingredients exhibit unique health-promoting properties—foxnut is rich in plant proteins and minerals, water chestnut flour provides resistant starch and a low glycemic index, and flaxseed contributes omega-3 fatty acids and lignans. Together, they enhance the fiber content, antioxidant potential, and glycemic suitability of the final product. The study examines traditional and industrial khakhra preparation techniques, nutritional compositions, market trends, and the functional potential of these ingredients in gluten-free formulations. Despite individual studies supporting their efficacy in baked products, there is limited exploration of their synergistic role in khakhra. This review addresses that gap by analyzing their combined application and its implications on product quality and market viability. The formulation promises not only to meet dietary restrictions but also to align with modern preferences for sustainable, functional, and culturally rooted snack options.
