Effect of Cyclodextrins on the Thermal Epimerization of Tea Catechins
tea catechins thermal epimerization cyclodextrin
2009/5/8
The epimerization reaction of tea catechins was investigated at pH 5.5 and 120 °C in the absence/presence of cyclodextrins (CDs). In the absence of CDs, a considerable quantity (∼20%) of product...
