Compound enzyme preparation for improving smoking quality of Yujin tobacco leaves and application of compound enzyme preparation in threshing and redrying process

The invention discloses a compound enzyme preparation for improving smoking quality of Yujin tobacco leaves and an application of the compound enzyme preparation in a threshing and redrying process. The compound enzyme preparation comprises the following components in parts by weight: 0.5-3.0% of alpha-amylase; 0.5-2.5% of compound cellulase; 0.2-3.0% of pectinase; 0.1-0.5% of nicotine dehydrogenase; 0.5-2.0% of papain; 10-20% of an enzyme activity stabilizer; and the balance of deionized water. The compound enzyme preparation is added on the basis of not changing the original redrying process, the process is simple, the operation is convenient, the chemical components of the Yujin tobacco leaves can be further coordinated, the irritation and the green offensive odor are reduced, the aftertaste is improved, the gentle and fine degree of the smoke is improved, the quality grade of the tobacco leaves is improved, and the use value of the tobacco leaves is widened. 本发明公开了一种用于提高豫产烟叶吸味品质的复合酶制剂及其在打叶复烤工艺中的应用。所述复合酶制剂
