摘 要: | 以玉米淀粉为原料,研究了玉米多孔淀粉制备过程中各种因素对产物成孔效果的影响,探讨了酶解成孔的机理,并对制备工艺进行了初步优化.在糖化酶和耐高温α-淀粉酶混合成的复合酶作用下,玉米淀粉水解制备玉米多孔淀粉的最佳工艺为:加酶量为按照理论水解55%淀粉的30倍加入量,糖化酶与耐高温α-淀粉酶的配比7:1,反应体系pH值5.6,酶解温度60℃,淀粉浓度60%,反应时间20h.反应后玉米淀粉的吸油率由16.15%提高到了47.59%.

Abstract: | This paper aims to have a discussion about the effect of the different conditions on the porosity of corn porous starch, and the possible mechanism. Optimal corn porous starch processing conditions are determined as follows: complex enzyme that could theoretically hydrolyze 30 times of 55% of the added raw starch; ratio of α-1,4-glucanglucohydrolase to α-amylase 7:1; pH 5.6; temperature 60℃; starch solid concentration (w/v) 60%; reation time 20h. The result shows that after the reaction the oil adsorption ratio of corn starch was increased from 16.15% to 47.59%. |
