| Abstract: | This paper presents the solvent extraction method and ions precipitation method(Zn2+) for the distillation of tea polyphenol.The authors use single factor experiment and orthogonal experiment separately,and discuss the best distilling technical parameters,such as enthanol concentration,grinding granularity,temperature of extraction,times of extraction,ratio of material to solvent and extraction time.At last,the best conditions of extraction are attained as follows: enthanol concentration is 20%,grinding gra... |
