| Abstract: | Tea polysaccharides were extracted by enzyme hydrolysis method.the effect of concentration,pH and temperature on content of polysaccharides was studied respectively.And the yield rate,neutral tea polysaccharides,acidic tea polysaccharies and protein content were studied.The optimum process conditions of enzymatic extraction technology were determined as following:the enzyme concentration,0.8%,pH 8.77;temperature 58.9 ℃.Under this condition,the yield rate reached to 2.01%,neutral tea polysaccharides content was 54.27%,acidic polysaccharides content was 15.41% and protein content was 7.91%. |
