| 摘 要： | 以海带作为原料，通过单因素试验和正交试验，研究了盐酸和柠檬酸质量分数、提取温度、提取时间、固液比对海带汁中多糖和甘露醇提取率的影响。试验结果最适提取条件为：提取液为1.0%盐酸、提取温度为100℃、固液比为1：30、提取时间4 min。在此条件下对海带多糖和甘露醇进行提取得到多糖质量浓度为3.464 mg/g、甘露醇为152.963 mg/g。

| Abstract: | In this experiment, Laminaria japonica as raw material was used to study the factors affecting the leach rate of polysaccharides and mannitol, including hydrochloric acid and citric acid content, temperature, time, solid-liquid ratio. Single factor and orthogonal experiments were done to determine the best leach con-ditions which was found as 1. 0% HCl, 100℃, 4 mins and at solid-liquid ratio of 1：30. Under this condi-tion we obtained 3. 464 mg/g polysaccharides and 152. 963 mg/g mannitol. |
