摘　　要：以桃胶多糖提取率为考查指标,通过单因素试验考查了料液比、pH值、温度和时间等对桃胶中多糖提取率的影响规律;随后采用L_(9)(3^(4))正交试验进行提取工艺的优化研究。影响桃胶多糖提取率的主次因素依次为料液比>pH值>浸提温度>浸提时间。通过正交试验优化桃胶多糖提取最佳工艺参数为浸提温度60℃,料液比90∶1,pH值10,浸提时间3 h,此条件下桃胶中多糖的提取率为85.7%。Taking the extraction rate of peach gum polysaccharide as the index,the effects of liquid-solid ratio,pH,temperature and time on the extraction rate of peach gum were investigated by single factor experiment;Then L_(9)(3^(4))orthogonal experiment was used to optimize the extraction process.The primary and secondary factors affecting the extraction rate of peach gum polysaccharide were liquid-solid ratio>pH>temperature>time.The optimum extraction parameters of peach gum polysaccharide were optimized by orthogonal experiment:temperature 60℃,liquid-solid ratio 90∶1,pH 10 and time 3 h.under these conditions,the extraction rate of peach gum polysaccharide was 85.7%.
