利用现代生物技术提高茶叶品质

以基因工程、细胞工程、酶工程、发酵工程为主的现代生物技术,目前在各行业已得到广泛的应用,在茶学领域中起步较晚,但应用前景广阔.本文简述了在茶树育种、茶叶加工中应用基因工程、细胞工程改良茶树品种或创造茶树优良新品种的应用情况和发前景.提出在茶叶加工环节中应用酶工程,利用酶的高效生物催化功能,促进茶叶内不利成分及无效成分有...

To improve tea's quality by means of modern biological technology

The modern biological technologies in aspects of gene engineering,cell engineering,enzyme engineering and fermentation engineering have been applied extensively in many industries,but late in tea industry,however,it potential will be great.This paper has introduced the application situation of biological technology in variety improvement and suggests fermentation engineering will be applied in processing to promote the change of elements in tea for better quality.The fermentation technology can speed up beneficial microorganisms’ growth,constrain the deleterious ones and shorten fermentation period,meanwhile,to control the contents of tea polyphenois,TB and tea polysaccharide so as to improve the tea quality.
