摘要
通过α-淀粉酶对木薯淀粉进行改性。结果表明:α-淀粉酶酶解木薯淀粉可以得到25%高固含量和13.8mPa.s低粘度的改性淀粉糊液,为表面施胶创造良好条件。在对新闻纸进行表面施胶时,酶解淀粉不仅能改善纸张的施胶度,而且还能改善纸张的强度性能。
The results of the α -amylase modification on the tapioca starch show that α -amylase enzymolysed tapioca starch can yield the modified starch solution of 25% in solid content and 13.8mPa. s in viscosity, thus providing a better condition for surface sizing. When surface sizing was applied for newsprint, the enzymolysed starch can improve not only the degree of sizing of the paper, but also the strength property of paper.
