Application of Enzymes in Paper Documents Restoration

Abstract

Abstract: Physical means and water treatment are often applied to paper cleaning and remounting during the process of restoration. However, when it comes to seriously damaged paper in ink or pigment, careless treatment can easily do harm to paper documents. Enzymes can catalyze the hydrolysis of adhesives, therefore, fragile documents would be separated easily with less physical damage. In this article, the related researches at home and abroad on the application of three common types of enzymes, namely, alpha-amylase, protease and lipase, in the process of cleaning and remounting are introduced, whereas influencing factors, application effects as well as safety of enzymes are analyzed in order to provide some guidance in actual restoration work.
