A kind of enzymolysis method for tobacco stem processing

Abstract

The invention relates to the field of cigarette processing. A tobacco stem processing method using tobacco stems to enhance flavor comprises the following steps: (1) stem washing enzymatic treatment: when washing stems, the tobacco stems and washing water flow relatively; the tobacco stems and washing water The mass ratio of the stem water is 1:10-100; the stem-washing water is added with a stem-washing compound enzyme equivalent to 0.01-0.5% of the mass of the tobacco stems, and the stem-washing compound enzyme is composed of pectinase with a mass fraction of 30-70% and 70-30% xylanase; (2) pressed stems and cut stems; (3) second enzymatic hydrolysis treatment: adding a hydrolysis compound enzyme equivalent to 0.01-0.5% of the weight of stems to the cut stems , reacting for 0.5-2h; the hydrolysis compound enzyme is composed of protease, amylase, cellulase, and hemicellulase, and the weight ratio of the four enzymes is 5-1:1:2:1 in turn. The method provided by the invention can not only effectively remove part of the cell wall substances to coordinate chemical components, but also avoid the loss of aroma components in the soaking enzymolysis process, so as to effectively improve the taste absorption.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to an enzymatic hydrolysis method in the process of tobacco stem processing. Background technique [0002] Although tobacco stems are a component of tobacco, their physical and chemical properties are quite different from those of tobacco leaves. The sugar content of tobacco stems is low, and the content of nicotine and aroma substances is lower, which is about 20-25% of the leaves. These differences cause the tobacco stems to be poor in aroma, flat in taste, heavy in woodiness, and highly irritating, which limits the application of shredded stems. [0003] At present, the conventional treatment process of tobacco stems is as follows: [0004] Stem washing → heating of tobacco stems → storage of stems → heating of tobacco stems → pressing of stems → shredding of stems → feeding of shredded stems → puffing and drying of shredded stems → winnowing → storage. [0005] 1. In the existing stem w...

Problems solved by technology

However, since the process of making tobacco stems into shredded stems includes processes such as washing, storing, and moistening stems, and then pressing and cutting stems, etc., if the enzymatic hydrolysis process is added before washing stems, it will make the tobacco The time required for the stalk production process is further extended. Using the existing method, the entire treatment process takes more than 8 hours, which not only consumes the storage space of the production line; Complicated, which limits the effective application of this method in the production of shredded tobacco stems
