Abstract

The invention discloses a method for producing cigarette expansion cut tobacco with low tar content and low harm by using microbial fermentation and particularly relates to a method for producing expansion cut tobacco with low tar content and low harm by using quick fermentation of discarded tobacco leaves by using safe good-grade microorganisms and then using a process for expanding cut leaves with CO2. The method specifically comprises the following steps: after the discarded tobacco leaves are threshed and redried or before the discarded tobacco leaves are produced into expansion cut leaves, inoculating one or more than two kinds of strains with different concentrations; after the discarded tobacco leaves are threshed and redried, carrying out microbial mild fermentation within the alcoholization period of one to two years; and before the discarded tobacco leaves are produced into expansion cut leaves, carrying out artificial quick fermentation for 24-72 hours and then intercepting the enzyme activity by adopting the process for expanding the cut leaves through a parameter-optimized CO2 method and using high temperature in the expansion process to obtain the expansion cut tobacco leaves with enhanced compatibility and reduced tar and CO release amount. According to the method, due to the utilization of the safe food-grade microorganisms and high-temperature enzyme activity interception in the expansion process, the expansion cut tobacco leaves obtained by production have the advantages of favorable tar and harm reducing effects, favorable repeatability and low cost; the operation process is simple and safe; and a cigarette formula is easily used.

Description

technical field [0001] The invention relates to the field of biotechnology and the field of expanded shredded leaf production, more precisely, it utilizes microorganisms to treat low-grade tobacco leaves, and the processed low-grade tobacco leaves are subjected to CO 2 To expand the shredded tobacco to reduce the tar and CO emission of shredded tobacco. Background technique [0002] my country is very rich in tobacco leaf resources, with a planting area of ​​15 million mu and a production of about 35 million tons of tobacco leaves (1 load is about 50kg), ranking first in the world. In the process of tobacco planting and production, a large amount of low-grade tobacco leaves are produced, accounting for about 25% of the total output, plus each tobacco company still has a large number of sporadic tobacco leaves and risky tobacco leaves in the warehouse, wasting a lot of money and warehouse space resources, so the effective use of these tobacco leaves is to reduce the production...
