Teachers from the College of Agriculture of Jiangxi Agricultural University have made new progress in the research of the quality chemistry of Ninghong tea

Ning black tea is mainly produced in Xiushui County, Tonggu County, Wuning County and other places in Jiangxi, and is one of the earliest black teas in China, enjoying the reputation
of "tea cover China, price in the world".
As the only representative of black tea in the "four green and one red" development strategy of the tea industry in Jiangxi Province, Ning black tea is known for its beautiful ropes, golden milli revealing, sharp seedlings straight, dark color, mellow and sweet taste, high and lasting internal fragrance and bright red and bright leaf base
.
In recent years, the teachers of tea science at the College of Agriculture of Jiangxi Agricultural University have conducted research on the formation of flavor substances during the processing of Ninghong tea, the formation of aroma substances during fermentation and the enzymatic mechanism of key enzymes in vitro in fermentation, which has further strengthened the theoretical basis of the quality formation of Ninghong tea and promoted the technological innovation
of Ninghong tea processing technology.

 

The results of the study are "Multi-omics and enzyme activity analysis of flavour substances formation: Major metabolic pathways alteration during Co.
" ngou black tea processing", recently published
in Food Chemistry (CAS Region I, IF 9.
