摘要
我国是产茶大国,茶叶的综合利用一直是茶产业发展的重要方向.采摘、生产、饮用茶叶的同时,产生了大量的茶叶副产物,例如茶汁、茶渣和茶粉等.茶叶副产物中含有大量的生物活性物质,如多酚类(儿茶素、黄酮类、原花青素)、色素、生物碱类(咖啡因、茶碱、可可碱)、氨基酸以及茶多糖等;具有抗病毒、抗氧化、降血糖及改善肠道健康等生物学功能.茶叶副产物可以有效提高动物的生产性能及畜产品品质,增强机体抗病能力,在畜牧养殖领域应用较为广泛.文章综述了茶叶副产物的活性成分、生物学功能以及在动物生产中的应用,为茶叶副产物在动物生产中的进一步推广与利用提供参考.
Abstract
China is a major tea-producing nation,and the comprehensive utilization of tea has always been an important direction for the development of the tea industry.In addition to the picking,production,and consumption of tea leaves,a large amount of by-products are generated,such as tea juice,tea residue,tea powder,and so on.These tea by-products contain a number of bioactive substances,such as polyphenols(catechins,flavonoids,proanthocyanidins),pigments,alkaloids(caffeine,theobromine,theophylline),amino acids,and tea polysaccharides,etc.They exhibit various biological functions,including anti-virus,anti-oxidation,blood glucose reduction,and gastrointestinal health improvement.Tea by-products can effectively enhance productivity and the quality of livestock products,as well as strengthen the body's disease resistance.Tea by-products are increasingly applied in livestock farming,with widespread applications in animal production.The article reviews the active ingredients and biological functions of tea by-products,as well as their applications in animal production,providing a reference for the further promotion and utilization of tea by-products in animal production.
