中文摘要:

      以海带为原料，采用单因素实验和正交实验，研究了浸提温度、浸提时间、pH以及料液比等条件对海带中碘、甘露醇及多糖等活性成分浸出率的影响，确定了最佳浸提条件为：料液比1∶30、浸提温度80 ℃、浸提时间9 h、料液pH为2.0。在此条件下的浸提结果为碘0.347 g/100 g、甘露醇29.104 g/100 g、总糖3.502 g/100 g。

英文摘要:

      In this experiment, kelp as raw material was used to study the factors affecting the leach rate of iodine, mannitol and polysaccharides,including temperature, time, pH and solid-liquid ratio. Single factor and orthogonal experiments were done to determine the best leach conditions which was found as 80 ℃,9h,pH 2.0,and at solid-liquid ratio of 1∶30.Under this condition we obtained 0.347 g iodine,29.104 g mannitol,3.502 g polysaccharides in 100g kelp.This experiment will provide reference data for kelp deep processing.
