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:
