The purpose of this invention is to provide a technique that uses a compositional innovation of a dry enzyme composition to improve the stability of a protein deamidase composition. The present invention enables improvement of the stability of a dry protein deamidase composition by making both a protein deamidase and magnesium chloride coexist in a dry enzyme composition, or making adjustments sothat the pH is at least 2 and less than 5 when the composition is dissolved in water at a concentration of 1w/v%. 本发明提供一种通过干燥酶组合物的组成上的研究而提高蛋白质脱酰胺酶组合物的稳定性的技术。在干燥酶组合物中，通过使氯化镁与蛋白质脱酰胺酶共存，或者，调整为使其以1w/v％的浓度溶解于水中时的pH为2以上且小于5，可提高蛋白质脱酰胺酶干燥组合物的稳定性。
