摘要
Abstract
[Objective] The aim was to screen the optimum conditions for extracting water-soluble tea polyaaccharide from Pu'er tea by hot water extraction method. [ Method] By using hot water extraction method to extract water-soluble tea polysacoharide, according to the effects of extraction time, temperature, solid-liquid ratio, times on polysaccharide yield, the optimum factors were obtained through orthogonal test. [ Result] The order of influencing factors for tea polysaccharide extraction from FV er tea are extraction time > extraction limes > extraction temperature > solid-liquid ratio; the optimum extraction conditions are solid-liquid ratio 1:20 g/ml, temperature 90 ℃, time 1.5 h, extraction 2 times; under the above conditions, the optimum extraction rate is 54. 5%. [ Conclusion] The study will provide basis for lea polysaccharide extraction from Pu'er lea.关键词
