    摘要:

    玉米淀粉加工复合酶制剂是玉米淀粉加工专用酶制剂,主要由纤维素酶、木聚糖酶等组成。为了探讨复合酶制剂在玉米淀粉湿法加工过程中的工艺效果,通过复合酶制剂在玉米纤维洗涤过程中的应用,考察经过酶反应处理后玉米粉浆粘度和纤维吸水性的变化,以及淀粉和蛋白质收率、蒸汽消耗量等指标。结果表明,酶制剂能够将玉米的胚乳淀粉细胞壁及种皮纤维裂解,纤维洗涤顺畅,纤维中游离淀粉含量由4.1%降到2.4%,提高淀粉收率0.07%;脱水后纤维水分降低3.7%,有效降低了纤维干燥工序蒸汽消耗量。应用试验研究得到如下结论:复合酶制剂的使用能够快速有效降解玉米粉浆粘度和纤维吸水性,高效分离淀粉和蛋白质,改善对纤维的洗涤效果,提高淀粉和蛋白质收率,降低汽电消耗,提高设备利用率。

    Abstract:

    Corn starch processing complex enzyme is a special enzyme product, mainly composed of cellulase and xylanase, for corn starch processing. In order to explore the technological effect of complex enzyme in the wet processing of corn starch, the application of complex enzyme in the washing process of corn fiber was studied in this paper. The changes of viscosity of corn starch slurry and the water absorption of fiber, yield of starch and protein, steam consumption and other parameters after enzyme reaction were investigated. The results show that the enzyme could decompose the endosperm starch cell wall and seed coat fiber of corn, wash the fiber smoothly, reduce the free starch content from 4.1% to 2.4%, increase the starch yield by 0.07%, reduce the fiber moisture by 3.7% after dehydration, and save steam consumption effectively in the fiber drying process. The results of research on application test are as follow: the use of composite enzyme preparation can quickly and effectively degrade the viscosity of corn starch slurry and the water absorption of fiber, effectively separate starch and protein, improve the washing effect of fiber, increase the yield of starch and protein, reduce the consumption of steam and electricity, and improve the utilization rate of equipment.
