中文摘要: 对影响天麻多糖提取率的酶用量、提取时间、提取温度及 pH 值进行单因素试验,并使用正交法得到酶法提 取天麻多糖最佳工艺。结果表明,提取天麻多糖最佳工艺为酶用量 8 mg/g,提取时间 110 min,提取温度为 40 ℃,pH 值 为 4.5,在最优提取工艺条件下,天麻多糖提取量为 46.63 mg/g。
Abstract:Influencing factors which affected the extraction yield of polysaccharide in Gastonia elate was stud- ied, including enzyme amount , temperature, time, and pH, and the extraction conditions of polysaccharide in Gastonia elate were optimized by orthogonal experiments. Result as follows: the enzyme amount was 8 mg/g, the enzymatic hydrolysis time was 110 min, the enzymatic extraction temperature was 40 ℃, the pH was 4.5, and the polysaccharide in Gastonia elate was 46.63 mg/g under the optimum conditions.
