茶与茶渣的高值化综合利用

中国既是茶的原产地,也是茶的生产与消费大国,每年由于茶饮料及茶叶深加工产生大量的茶渣,仅仅以简单地丢弃处理而没有被高值化综合利用,既给环境带来了巨大的压力也造成了资源的浪费。茶渣中含有10%至16%粗纤维以及少量的络合态色素、矿物质、氨基酸、茶多酚、咖啡碱等,可以被多种形式地精深加工利用。本文综述了茶渣作为主要配料在作菌类的培养基、动物饲料的添加剂、植物的土壤肥料等方面的应用,以期为茶与茶渣的研究与利用提供参考。

High-value comprehensive utilization of tea and tea residue

China is not only the origin of tea, but also a big country in the production and consumption of tea. Every year, a large amount of tea residue is produced by tea beverage and deep processing of tea. However, it is simply discarded and not used for high value, which not only brings great pressure to the environmental, but also causes waste of resources. Tea slag contains 10% to 16% crude fiber and a small amount of complex pigment, minerals, amino acids, tea polyphenols, caffeine, etc., which can be processed in various forms. This paper reviewed the application of tea residue as the main ingredient in the culture of fungi, the additives of animal feed, the soil fertilizer of plants and so on, in order to provide reference for the research and utilization of tea and tea residue.
