摘　　要：【目的】研究利用α-淀粉酶对木薯淀粉进行降解制作粉状木薯淀粉胶黏剂的方法。【方法】通过单因素和正交实验确定酶水解木薯淀粉的最佳工艺条件。【结果】酶水解木薯淀粉的最佳工艺条件为:A2C3B2,即酶用量为1.0%,酶解温度为45℃,酶解时间为15min。按此条件所得的成品木薯淀粉胶的粘合强度为13.9038N·cm-2,粘度为1.0477Pa·S,不添加其他物质,粘合强度强,流动性非常好。【结论】该方法具有低成本,无污染和高效的特点。[Objective]To study an approach of preparing powdered cassava starch adhesive, which starch was degraded byα-amylase.[Methods]Through the single factor and orthogonal experiments to determine the optimum process conditions of enzymatic hydrolysis of cassava starch.[Results]The optimal process condition of enzymatic hydrolysis of cassava starch was the hydrolysis of cassava starch with 1.0% enzyme dosage at the temperature of 45℃ for 15min,which is so called A2 C3 B2 .This kind of cassava starch adhesive has strong adhesive strength,good fluidity and without additive,and its adhesive strength was 13·9038 N·cm-2 , and the viscosity was 1·0477 Pa· S.[Conclusion]The method has the characteristics of low cost,non-pollution and high efficiency.
