中文摘要:

      动物血液作为畜禽屠宰及加工的主要副产物, 富含蛋白质、微量元素、矿物质、激素、维生素、酶类等多种功能成分, 营养价值较高。其中, 蛋白质作为动物血液的主要营养成分, 占动物全血含量的10%~20%, 其氨基酸组成丰富, 富含赖氨酸, 是一种优质的动物蛋白资源, 素有“液态肉”之称, 具有广阔的开发应用前景。本文主要综述动物血液蛋白质的研究进展及开发应用现状, 重点总结了近年来以动物血液蛋白为原料开发的具有特定生理功能的生物活性肽, 如抗氧化肽、抗菌肽、免疫调节肽、抗癌肽、降血压肽、抗糖尿病肽等, 对活性肽的结构、序列及活性功能进行系统阐述, 并对动物血液蛋白实际应用中出现的问题以及未来发展趋势进行展望, 旨在为动物血液蛋白的高附加值开发利用提供参考。

英文摘要:

      As the main by-product of livestock and poultry slaughter processing, animal blood is rich in protein, trace elements, minerals, hormones, vitamins, enzymes, and has high nutritional value. Protein as the main nutritional components of animal blood, accounting for 10%?20% of the total blood content of animals. The amino acid composition is rich in blood, especially rich in lysine, is a kind of high-quality animal protein resources, known as “liquid meat”, and has a good application prospect. This paper mainly reviewed the research progress and development and application status of animal blood proteins, focused on the recent years of animal blood proteins as raw materials to develop biological active peptides with specific physiological functions, such as antioxidant peptides, antihypertensive peptides, antibacterial peptides, hypoglycemic peptides, anticancer peptides, anti-diabetic peptides and other peptides, and systematically described the structure, sequence and functional activity of bioactive peptides, as well as prospected the problems encountered in practical applications and the future development trend of animal blood, to provide reference for the development and utilization of animal blood protein with high added value.
