| 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15 min。按此条件所得的成品木薯淀粉胶的粘合强度为13.9038 N·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。 |

| Abstract: |
| [Objective] To study an approach of preparing powdered cassava starch adhesive, which starch was degraded by α-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 A2C3B2. 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. |
