摘　　要：目的研究保鲜纸涂层氧化淀粉胶对保鲜纸中NaClO_2留存率和ClO_2释放规律的影响。方法通过保鲜纸表面及横切面的SEM图片,确定保鲜纸的结构特点,采用纸基表面涂布氧化淀粉胶的方法,用碘量滴定法计算保鲜纸中NaClO_2的留存率和ClO_2的释放量。结果保鲜纸纸基表面形成的氧化淀粉胶层可以有效降低保鲜纸基结构对NaClO_2留存率和ClO_2释放量的影响,NaClO_2的留存率和ClO_2的释放量得到了提高,ClO_2的释放总量为3.4786mg,增加了70.82%。结论氧化淀粉胶涂层提高了NaClO_2的留存率和ClO_2的释放量。The work aims to study the effect of oxidized starch adhesive of preservative paper coating on NaClO_2 retention rate and ClO_2 release rule of the paper. Through the SEM image of the surface and cross section of the preservative paper, its structure characteristics were determined. Oxidized starch adhesive was coated on the paper base surface, and the NaClO_2 retention rate and ClO_2 release of preservative paper were calculated by the method of iodimetry. The oxidized starch adhesive coating formed on the surface of the paper could effectively reduce the influence of the paper base structure on the NaClO_2 retention rate and ClO_2 release. NaClO_2 retention rate and ClO_2 release increased, and the total release of ClO_2 was 3.4786 mg, which was 70.82% higher than before. The oxidized starch adhesive coating has improved the NaClO_2 retention rate and ClO_2 release.
