摘　　要：为探讨酶改性淀粉在书画装裱中的应用,用α-淀粉酶对浓度为10%的小麦原淀粉进行改性,制得装裱胶粘剂,其最佳制备条件为:α-淀粉酶用量对绝干淀粉量11U/g,反应温度60℃,pH=6.6,反应时间25min,所得溶液粘度为2.0mPa.s。经在书画装裱中的实际试用表明,酶改性淀粉与传统小麦面粉浆糊相比,不仅具有较高的稳定性,良好的抗霉变性能,还可提高宣纸的强度性能,利于裱件的长期保存。实验结果提示,α-淀粉酶改性淀粉有可能替代传统胶粘剂,值得进一步研究。The process condition of modification starch used in mounting with a - enzyme is discussed;the solid condition is 10%. Through experiment, the best process condition is testified, keeping temperature at 60℃ for 25min,pH at 6.6,the usage of a- enzyme is 11U/g to the usage of starch and the viscosity of the starch is 2.3mPa . s. Compared with wheat flour, enmymolysed starch has better stability and mildew resistance. Besides, it can also improve the strength of xuan - paper, favourable for long term conservation of calligraphy and painting.
