摘　　要：在单因素试验的基础上，选择L9（3^4）正交试验对虾壳粉的生物酶解脱乙酰工艺进行优化，结果表明，底物浓度为25％，发酵温度为45℃时，发酵时间48h，pH为5．0时，甲壳素的脱乙酰度达到最大值39．20％。On the basis of single factor experiment, shrimp shell powder enzyme release acetyl process is optimized by L9（34） orthogonal experiment, the results showed that the substrate concentration was 25 %, fermentation temperature 45 ℃, 48 h of fermentation time, pH was 5.0, attain to the maximum degree of chitin by 39.20 %.
