水浸提绿茶有效成分的工艺优化研究
Optimization of Water Extraction Technology on Active Components from Tea Leave
摘要
Abstract
The water extraction experiments were carried out in order to investigate the effect of the extraction process on the active components from green tea leave. Based on the Box-Benhnken central composite design principles, the extraction conditions of tea polyphenols optimized by the response surface analysis after the single factor experiment were that the rate of tea leave and water was 1:54.9 (W/V), the temperature of extraction was 46.2%, the time of extraction was 9.6 min, and the extraction times was 2. The effect of extraction process on caffeine and amino acids were clearly explored by auxiliary analysis. The results could be provided significant basis for separation and concentration of efficacious substances in green tea leave by the combined process of water extraction and membranes.关键词
