Problems solved by technology

When this patent processes low-grade tobacco leaves, it needs to carry out enzymatic hydrolysis reaction for 22-26 hours under the condition of humidity 60-70% and temperature 30-50°C, so special workshop or equipment is required, which will inevitably increase the operation cost and complexity; The amount of enzyme used in this patent is very large, resulting in increased protein residues in the tobacco leaves; at the same time, at least 12% of water is required to increase the moisture in the tobacco leaves during the treatment, and the structure of the tobacco leaves will definitely be tight during the second baking. , the expansion rate decreases, resulting in a decrease in the filling rate of shredded tobacco, insufficient burning of shredded tobacco, and an increase in CO content; it can be seen from the test data that the nicotine in the treated tobacco leaves has increased to varying degrees, and the nicotine content High, the irritation will be enhanced and will produce a spicy taste

Abstract

A preparation of increasing the quality of tobacco leaf features it contains cellulase, proteinase, pectinase, amylase, beta-amylase and yeast powder. It can speed up the process of natural ageing of tobacco and shortening natural ageing cycle of tobacco.

Description

technical field [0001] The invention belongs to the improvement of the formulation and treatment method of a treatment preparation for improving the quality of tobacco leaves, and relates to the technical field of biological enzymes. Background technique [0002] Tobacco leaf fermentation is one of the important steps in tobacco processing. At present, in the actual production process, artificial fermentation is still the main method of tobacco leaf fermentation. Since artificial fermentation can only slightly improve the quality of tobacco leaves, natural aging of tobacco leaves can greatly improve the quality of tobacco leaves. However, it has a long cycle and slow capital turnover. It is the main factor that restricts the further improvement of cigarette quality and economic benefits in many tobacco factories, and the use of biotechnology can solve this problem well. After searching, the relevant patents are: ① Chinese patent application number 03114578.7, which disclose...
