Abstract
Aims: The growing demand for plant-based and functional foods has sparked increased interest in flaxseed, a nutrient-dense seed recognized for its rich content of omega-3 fatty acids, dietary fiber, and lignans. This review aims to explore the nutritional enhancement and application potential of sprouted flaxseed as a vegan-friendly source of omega-3, particularly alpha-linolenic acid (ALA), in the formulation of food supplements.
Methodology: A comprehensive review of recent literature was conducted to evaluate the sprouting process and its impact on the nutritional profile of flaxseed. Emphasis was placed on changes in bioavailability, antioxidant activity, and reduction of anti-nutritional factors. The review also assesses technological advancements in product development and the incorporation of sprouted flaxseed in food matrices such as shakes, bars, and bakery products.
Results: Sprouting significantly enhances the bioavailability of ALA and other bioactive compounds in flaxseed by increasing enzymatic activity, reducing phytic acid, and improving protein digestibility. The application of sprouted flaxseed in functional food formulations has been shown to improve texture, nutritional value, and shelf stability. Moreover, studies suggest positive impacts on cardiovascular health, anti-inflammatory activity, and metabolic regulation when included regularly in the diet.
Conclusion: Sprouted flaxseed holds strong potential as a sustainable, functional ingredient for omega-3 supplementation in vegan and vegetarian diets. This review underlines the importance of optimizing sprouting conditions and processing technologies to fully harness its health benefits and industrial applicability, particularly in clean-label and plant-based food products designed for health-conscious consumers.
