以玉米淀粉为原料,以不同剂量γ射线辐照,然后用α-淀粉酶和糖化酶在酸性环境中、糊化温度以下酶解制备多孔淀粉. 探讨了反应时间、辐照剂量等因素对淀粉水解率和吸油率的影响,同时也用电镜观察了产物的形态. 结果表明,电镜下多孔淀粉形态与其水解率和吸油率相吻合,γ射线辐照能有效提高淀粉的酶解效率,可以大幅度提高多孔淀粉的吸油率.

In this paper,we useα-amylase and glucoamylase to hydrolyze the maize starch byγ-ray irradiation as raw materials in acidic environment less than the pasting temperature. The effects of reaction time ,irradiation dose and other factors on the rates of starch hydrolysis and oil-absorption were studied,and the product forms were also observed with electron microscope. The results show that the electron microscopic morphology and the rates of porous starch hydrolysis and oil-absorption are anastomose essentially,γ-ray irradiation can effectively improve the efficiency of enzymatic hydrolysis of starch,and can greatly improve the oil-absorption rate of porous starch.
