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9h、料液pH为2.0。在此条件下的浸提结果为碘0.347g/100g、甘露醇29.104g/100g、总糖3.502g/100g。
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.
