摘要
为研究卡拉胶酶固体酶制剂的喷雾干燥制备工艺条件,以卡拉胶酶酶活回收率为评价指标,在单因素实验的基础上,结合响应面分析法对卡拉胶酶固体酶制剂的喷雾干燥制备工艺进行优化,得到最佳喷雾干燥条件:麦芽糊精浓度27%,进风温度131℃,热风流量4.5 m^3/min,进料速度456 m L/h,喷雾压力0.2 MPa。在此条件下,酶活回收率达到56.9%±2.1%,与理论最优值56.1%接近。
In order to study the conditions of solid carrageenase preparation by spray drying, the conditions were determined by single factor test with the recovery of carrageenase activity as the evaluation index. Then the optimum conditions were determined by the response surface analysis method on the basis of the results of single factor experiment.The optimized spray drying parameters were shown as follows ：mahodextrin 27% ,inlet air temperature 131℃ ,hot air flow rate 4.5 m3/min, feeding speed 456 mL/h, atomizer pressure 0.2 MPa.Under the optimal process condition, the enzyme recovery of carrageenase reached 56.9% ±2.1% ,which was close to the theoretically predicted value of 56.1%.
