摘要
本研究以糙皮侧耳(Pleurotus ostreatus)固体发酵料为甲壳素制备材料,采用正交试验法,研究以该原料制备氨基葡萄糖盐酸盐工艺的最优化反应条件.常规水解条件下,在水解时间5h,水解温度90℃,盐酸的浓度为20%,甲壳素与盐酸的质量百分比为1:6,在此最佳工艺条件下得到的氨基葡萄糖盐酸盐最高产率可达25.29%.微波水解条件下,在压力0.2MPa,时间240s,盐酸浓度9.8%,仪器功率50%,在此最佳工艺条件下得到的氨基葡萄糖盐酸盐最高产率可达69.78%.水解产物通过FTIR的测定,微波水解的产物与常规水解的产物结构基本一致.
The chitin was made from the solid Pleurotus ostreatus leavening, and by using the orthwgonal testing method, an optimizing reacting condition for making glucosamine muriate from the chitin was studied. In the conventional hydrolization condition, the optimum time and temperature were 5h and 90℃ respectively, and the concentration of hydrochloric acid was 20%, the mass percentage of chitin to hydrochloric acid solvent was 1. 6. Under these optimal factors, the most efficient production rate would reach 25.29%. While microwave hydrolization showed that in these factors: pressure 0.2MPa, tinne 2400s, hydrochloric acid 9.8% and the instrument power 50% , the most efficient production rate was 68.08%. Through FTIR, the structure of the hydrolysates by microwave radiation and conventional hydrolization proved to be consistent on the whole.e
