摘要
为制备纳米级孔径多孔淀粉，提高多孔淀粉的比表面积和吸附性能，本研究设计了新型生物酶水解淀粉制备多孔淀粉的方法，制备出孔径50～300nm的纳米多孔淀粉。其最佳反应条件为：酶与原玉米淀粉质量比为1：100，a-淀粉酶与糖化酶质量比为10：1，反应36h。研制出的纳米级孔径多孔玉米淀粉，与传统多孔淀粉相比，比表面积和吸油率显著提高。
In order to prepare the nanoporous corn starch and improve the specific surface area, the new reaction condition was designed and nanoporous corn starch with 50 - 300nm pore size was manufactured. The optimal condition was：ratio of enzyme and corn starch 1 ： 100,mass ratio of s-amylase and saccharifying enzyme 10 ： 1,reaction time 36h. The specific surface and oil adsorption ratio of developed porous corn starch significantly increased, thus the adsorption performance was improved as well.
