And the article contained the following:
Instant green tea powder was used as raw material to prepare an instant dark tea via liquid-state fermentation by Eurotium cristatum. To understand how the chem. constituents present in fermented green tea develop during fermentation, samples were collected on different days during fermentation for qual. analyses by ultra-performance liquid chromatog.-Q Exactive Orbitrap/Mass spectrometry. Untargeted metabolomics analyses revealed that the levels of original secondary metabolites in the instant green tea changed significantly from day 3 to day 5 during fermentation Targeted metabolomics indicated that the levels of galloylated catechins (GCs) and free amino acids (FAAs) significantly decreased, but the nongalloylated catechins (NGCs), alkaloids, thearubigins and theabrownins increased dramatically after fermentation The changes in the contents of catechins, gallic acid and free amino acids in the instant dark tea samples were pos. related to the DPPH radical scavenging activities in vitro, and the phenolic acids and FAAs were pos. related to the inhibitory effects towards α-glucosidase. These results showed that fermentation by Eurotium cristatum is critical to the formation of certain qualities of instant dark tea. The experimental process involved the reaction of 5-(Hydroxymethyl)pyrimidine-2,4(1H,3H)-dione(cas: 4433-40-3).Recommanded Product: 4433-40-3
