摘要
以黄肉甘薯为材料,探索了水提法制备甘薯糖蛋白的工艺。通过单因素和正交试验,得出制备甘薯糖蛋白的最优工艺条件:物料粒度为80目,浸提时间为1h,浸提温度为50℃,料液比为1∶15,浸提次数为1次。在该优化条件下甘薯糖蛋白的含量为17.730mg/g。方差分析表明,物料粒度、浸提时间、浸提温度和料液比对甘薯糖蛋白提取率的影响均不显著。
We studied the technology for extracting glycoprotein from yellow flesh sweet potato by water extraction. Based on the single factor and orthogonal experiments, we determined the optical extraction conditions： material granularity was about 80 meshes,extraction time 1.0 hour,extraction temperature 50℃,solid to liquid ratio 1：15, and extraction once.Under the optimal conditions, the glycoprotein from sweet potato was up to 17.730mg/g.The variance analysis showed that material granularity, extraction time, extraction temperature and solid to liquid ratio had no significant effect on the extraction rate.
