摘要

Agro-industrial oilseed meals (OMs) represent abundant, underutilized residues with significant potential to advance circular bioeconomy strategies through sustainable valorization. This review synthesizes current knowledge on the protein composition, functional properties, extraction methodologies, and emerging applications of predominant underutilized OM rapeseed, sunflower, flaxseed, pumpkin seed, grape seed, black cumin, and sesame meals highlighting their roles as renewable protein sources and functional ingredients in modern food systems. Comparative analysis of amino acid profiles, protein solubility, emulsification, foaming, and gelation behavior reveals distinct techno-functional niches for each meal, informing targeted processing and formulation. This review focuses on conventional and novel extraction techniques, including aqueous, enzymatic, membrane, and green solvent-assisted approaches, emphasizing yield, purity, environmental footprint, and scalability. Applications surveyed encompass protein-enriched foods, texturized meat analogs, emulsions, and fiber-protein composites, alongside innovative nanoencapsulation and delivery platforms that enhance bioavailability and stability of lipophilic and bioactive compounds. We propose research priorities: optimization of mild, high-efficiency extraction; tailored protein modification for functionality; life-cycle assessments to quantify sustainability gains; and interdisciplinary frameworks to bridge laboratory advances with commercial deployment. By aligning material science, process engineering, and policy incentives, OMs can be transformed from low-value by-products into versatile contributors to resilient, sustainable food systems.
