摘要: 以黑曲霉102-ZL为菌种,以麸皮和稻草粉为主要原料,采用固体发酵方法生产果胶复合酶,浸提后将粗酶提取液用于亚麻粗纱煮练。以煮练后亚麻粗纱的残胶率和强力为指标,通过单因子和正交试验对亚麻粗纱果胶复合酶煮练的酶液浓度、处理温度、处理时间、EDTA添加量和酶液pH初始进行了优化。结果表明,适宜果胶酶浓度为75μ/mL,适宜处理温度为40℃,适宜处理时间为4h, EDTA适宜添加量为6mmol/L,适宜pH为5~5.5。在此条件下,煮练亚麻粗纱残胶率为15.80%,强力为975CN,能够满足纺纱工艺要求。

Abstract: The pectin compound enzymes were produced by solid state fermentation using Aspergillus niger 102-ZL, and the wheat bran and rice straw powder were used as main material. The crude pectin compound enzymes liquid was obtained by extracting, and to be used in flax roving scouring. Taking the residual gum content and the strength of scouring flax roving as target, the five parameters (enzyme concentration, treating temperature, time, EDTA addition and pH) of flax roving scouring were optimized using single factor and orthogonal test. The results showed that the optimal enzyme concentration, treating temperature, time, EDTA addition and pH were 75μ/mL, 40℃, 4h, 6mmol/L and 5~5.5 respectively. Under the optimal condition, the residual gum content and the strength of scouring flax roving were 15.80% and 975CN respectively, and the flax roving could meet the requirements of spinning process.
