Abstract: Whey protein is an important source of natural bioactive peptides with high biological value. Milk derived bioactive peptides with antioxidant, hypoglycemic, hypoglycemic and other biological activities are commonly used as raw materials for the manufacture of health products and functional foods due to the high specificity, low toxicity, diverse structures and low molecular mass and have a wide application prospect in the prevention and treatment of diseases. In this paper, the sources and structures of milk derived bioactive peptides are briefly reviewed, with emphasis on the extraction methods and biological functions of bioactive peptides, in order to provide a reference for the efficient utilization of bioactive peptides and the development of functional dairy products.

Key words: bioactive peptide; enzymatic hydrolysis; microbial fermentation method; biological function

摘要： 乳清蛋白是天然生物活性肽的重要来源，生物学价值较高。其中，乳源生物活性肽被证实具有抗氧化、降血糖、降血压等多种生物活性，因其具有特异性高、毒性低、结构多样性高和分子质量低等特点，常被作为保健品和功能性食品原料，在预防和疾病治疗中应用前景广泛。本文简要概述乳源生物活性肽的来源与结构，重点阐述生物活性肽的提取方法和生物学功能，以期为生物活性肽的高效利用及相关功能性乳制品开发提供参考。
