Abstract
|
|
|
|
Pile-fermentation is a critical procedure for producing Chinese dark tea, during which thermophilic microorganisms would play an irreplaceable role. However, there have been little researches on the influences of thermophilic microorganism pile-fermentation (TMPF) in high-temperature of Chinese dark tea. Thus, we conducted high-performance liquid chromatography and nontargeted metabolomic to analyze the non-volatile metabolites of TMPF. Our results discovered that the amounts of (??)-epigallocatechin gallate, (??)-epigallocatechin, (??)-epicatechin gallate, and (??)-epicatechin were decreased significantly (p?
