Nutritional Fortification and Consumer-Centric Development: Integrating Water Chestnut into Sustainable Food Systems

Abstract

The global food system faces a dual challenge: the necessity of enhancing nutritional security and the requirement to transition toward sustainable consumption patterns as outlined by the EAT-Lancet Commission. This article investigates the potential of water chestnut (Trapa natans) as a versatile, nutrient-dense ingredient for functional food development. By synthesizing recent empirical research on the phytochemical, antioxidant, and physicochemical properties of water chestnut with established frameworks in consumer-driven product design, this study elucidates how this aquatic crop serves as a bridge between traditional agricultural practices and modern industrial food applications. The research explores the integration of water chestnut flour into various matrices-including bakery products and innovative snack formats-while addressing the critical nexus of sensory acceptability, market intelligence, and product innovation. The methodology adopts a multi-dimensional approach, incorporating sensory descriptive analysis, physicochemical characterization, and consumer acceptance testing. Findings indicate that Trapa natans possesses significant potential to enhance the nutritional profile of processed foods without compromising sensory quality, provided that processing parameters are optimized. The discussion provides a comprehensive analysis of the barriers to market entry, the role of consumer information in shaping preferences, and the strategic importance of aligning new product development with sustainability metrics. This article concludes that water chestnut, through its unique biological profile and adaptability, represents an underutilized resource that can contribute significantly to a healthier and more resilient global food architecture, provided that interdisciplinary efforts continue to bridge the gap between crop science and consumer psychology.
