Research Progress on Application of Hydrolyzed Protein from Animals in Pet Food

动物副产品是宠物粮食中水解蛋白的主要来源。近年来，宠物粮食生产行业已经开始合理利用酶水解后的动物蛋白产物，主要包括生物活性肽等低过敏性成分。除了具有较高的氨基酸生物利用率之外，蛋白质水解物释放的生物活性肽等物质还具有抗氧化、抗菌、免疫调节、组织修复、抗高血压和血糖控制作用，其中许多功能特性已在伴侣动物上进行了研究。本文重点综述了以生物活性肽为代表的动物蛋白水解物的生产、来源和应用，以及在对宠物健康影响上的研究进展，以期为宠物粮食中合理使用生物活性肽等动物蛋白水解物提供参考。Animal by-products are the main source of formulated proteins in pet food. In recent years, the pet food production industry has begun to effectively utilize enzymatically processed animal protein products, mainly including hypoallergenic ingredients such as bioactive peptides. In addition to having the same irritation and bioavailability, protein hydrolysates release bioactive peptides with antioxidant, antibacterial, immunomodulatory, tissue repair, antihypertensive and hypertension control effects, many of which have been studied in partner animals. The production, source and application of bioactive peptides, as well as the research progress on their impact on pet health, are discussed in order to provide a reference for the rational use of bioactive peptides in pet food.
