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:

Enrichment of Biscuits with Matcha Green Tea Powder: Its Impact on Consumer Acceptability and Acute Metabolic Response
TL;DR: Enriching biscuits with Matcha green tea is acceptable to consumers, but may not bring significant postprandial effects, compared to non-enriched biscuits consumed with water or MGTP drink.
