Bioactive peptides used for food preservation can prolong the shelf life through bacteriostasis and antioxidation. On the one hand, bioactive peptides can inhibit lipid oxidation by scavenging free radicals, interacting with metal ions, and inhibiting lipid peroxidation. On the other hand, bioactive peptides can fundamentally inhibit the growth and reproduction of microorganisms by destroying their cell membranes or targeting intracellular components. Besides, bioactive peptides are biocompatible and biodegradable in vivo. Therefore, they are regarded as a promising alternative to chemical preservatives. However, bioactive peptides are easily affected by the external environment in practical application, which hinders their commercialization. Currently, the studies to overcome the weakness focus on encapsulation and chemical synthesis. Bioactive peptides have been applied to the preservation of various foods in experimental research, with good results. In the future, with the deepening understanding of their safety and structure–activity relationship, there may be more bioactive peptides as food preservatives.

生物活性肽：用于食品保存的化学防腐剂的有希望的替代品

用于食品保鲜的生物活性肽可以通过抑菌和抗氧化来延长保质期。一方面，生物活性肽可以通过清除自由基、与金属离子相互作用、抑制脂质过氧化来抑制脂质氧化。另一方面，生物活性肽可以通过破坏微生物的细胞膜或靶向细胞内成分，从根本上抑制微生物的生长和繁殖。此外，生物活性肽在体内具有生物相容性和可生物降解性. 因此，它们被认为是化学防腐剂的有前途的替代品。然而，生物活性肽在实际应用中容易受到外界环境的影响，阻碍了其商业化。目前，克服这一弱点的研究主要集中在封装和化学合成上。生物活性肽已在实验研究中应用于各种食品的保鲜，效果良好。未来，随着对其安全性和构效关系认识的深入，可能会有更多的生物活性肽作为食品防腐剂出现。
