Green tea catechins during food processing and storage: A review on stability and detection
TLDR
In this paper, a pseudo first-order kinetic model has been developed and validated for the epimerization and degradation of tea catechins in several food systems, whereas the rate constant of reaction kinetics followed Arrhenius equation.About:

Tannase application in secondary enzymatic processing of inferior Tieguanyin Oolong tea
TL;DR: In this article, inferior Tieguanyin oolong tea leaves were treated with tannase, and the content and bioactivity of catechins in extracts from the treated tea leaves was investigated to assess the improvement in the quality of inferior OOLong tea, showing that after treatment, the esterified catechin content decreased by 235%, whereas non-galloylated catechi and gallic acid contents increased by 153% and 182%, respectively.

Investigating the Commercial Microwave Vacuum Drying Conditions on Physicochemical Properties and Radical Scavenging Ability of Thai Green Tea
TL;DR: In this article, the effects of drying conditions using a commercial microwave vacuum dryer on the physicochemical properties and antioxidant activity of Thai green tea were investigated, and the results showed that individual catechins, their total quantities, radical scavenging ability, and moisture content were significantly affected; however, total polyphenol content and color parameters were not significantly affected.
