 note = {In the conservation of East Asian paintings, most conservators deal with treatments which involve removing backing paper without any damage to the objects. As some paintings show their backing paper seriously deteriorated with paste, conservators need to take more time than in normal conditions to remove such backing paper. Enzyme treatment, especially α-amylase treatment is a possibility to remove the backing paper in this situation. On the other hand, it is necessary to consider the treatment of deactivation of the enzyme, because most paintings are re-pasted to be reassembled by starch paste after enzyme treatment. If α-amylase is still active after removing the old backing paper, the new backing paper cannot be pasted. This study aimed to apply α-amylase for mounted paintings and documents, for which starch paste is intended to be used after the treatment. First, the effectiveness of α-amylase in artificially aging paste was examined. Next, applications of ethanol to deactivate α-amylase were attempted. The enzyme acted on the sample of artificially aging paste, but the effect was slightly weaker than the samples with fresh paste. The ethanol treatment completely deactivated the enzyme in the case of an under the 1 vol% concentration enzyme solution. However, in the sample with the 2 vol% enzyme solution, the new backing paper sample shows lower adhesive strength even after the ethanol treatment.},
