Background Torreya grandis nuts bioactive peptides have gained attention as functional food ingredients owing to their diverse physiological effects, including antioxidant, anti-inflammatory, antihypertensive, antimicrobial, and antiobesity activities. These peptides represents a sustainable source of plant-based nutraceuticals. Scope and approach This review examines the nutritional profile, protein composition, and bioactive peptides of T. grandis, emphasizing advances in extraction techniques such as green solvents, notably deep eutectic solvents (DES), and enzymatic hydrolysis to enhance peptide yield and functionality. Key findings and conclusion DES extraction improved protein yield and preserved peptide functionality compared with conventional methods, yielding unique antioxidant peptides. Enzymatic hydrolysates exhibited enhanced biological properties suitable for food applications. Bioactive peptides exemplified by defensin 4 demonstrated antimicrobial effects against various pathogens. Additionally, T. grandis peptides showed potential in modulating lipid metabolism and gut microbiota, contributing to anti-obesity benefits. Nevertheless, challenges such as low bioavailability, enzymatic degradation, processing instability, and limited in vivo validation hinder their commercial use. Overcoming these limitations requires further mechanistic studies, and scalable production methods, including synthetic biology and advanced encapsulation technologies. Integration of omics approaches and AI-driven bioactivity prediction can accelerate discovery and commercialization. Collaborative interdisciplinary efforts are essential to fully realize the potential of T. grandis bioactive peptides as sustainable, health-promoting ingredients for managing oxidative imbalance. Although research on T. grandis protein shows promise, there is a lack of extensive comparative studies with proteins from other tree nuts. This highlights the necessity for additional research to explore
