荔枝粗多糖提取工艺的研究

The Extracting Techniques of Crude Litchi Polysaccharide

利用热水浸提三氯醋酸脱蛋白醇沉等工艺从荔枝干果中提取多糖,用蒽酮—硫酸法测定多糖含量,通过正交试验确定了提取多糖的条件。结果表明:荔枝多糖最佳提取工艺参数为:料液比1:50、浸提温度80℃、浸提时间4h。

By orthogonal design, the optimization of polysaccharide extraction from dried Lithchi fruit by water extracting and alcohol deposit was studied. The optimum extracting conditions were as follows： adding 50 times water in dried litchi and extracting at 80℃ for 4 hr.
