Abstract: A method of producing corn starch by enzymatic process involving: soaking the corn; crushing the corn, separating and washing embryo; fine grinding; washing and drying fiber; separating and drying protein; washing, dewatering and drying the starch. An enzyme preparation is added before the step of washing, dewatering and drying the starch; the enzyme preparation is cellulose, or xylanase, or combination of the cellulose and the xylanase; and addition of the enzyme preparation is from 0.001% to 0.08% by weight of the corn. Based on the technology of traditional wet process, the method of the present invention comprises a step of adding enzyme preparation in the process of separating the corn, which improves the effect and the efficiency of mechanical separation, and further improves the purity and yield of the substance separated while also reducing the energy consumption.

Abstract translation: 一种通过酶法生产玉米淀粉的方法，包括：浸泡玉米; 粉碎玉米，分离洗涤胚胎; 精磨; 洗涤和干燥纤维; 分离和干燥蛋白质; 洗涤，脱水和干燥淀粉。 在洗涤，脱水和干燥淀粉的步骤之前加入酶制剂; 酶制剂是纤维素或木聚糖酶，或纤维素和木聚糖酶的组合; 并且酶制剂的添加量为玉米重量的0.001％至0.08％。 基于传统湿法的技术，本发明的方法包括在分离玉米的过程中加入酶制剂的步骤，提高了机械分离的效果和效率，进一步提高了纯度和产率。 物质分离同时也降低能耗。
