Abstract

The invention discloses a tobacco stem microbiological treatment aroma increasing method. The tobacco stem microbiological treatment aroma increasing method is characterized by comprising the following steps that pediococcusacidilactici and bacillus subtilis are taken and inoculated in an LB fluid medium containing, by weight, 0.2% of trehalose; centrifugalization is carried out after culture, then sterile water is used for washing and settling, centrifugalization is carried out, a product is evenly oscillated with sterile water, and the product is diluted into a microbial agent for treatment when used; the microbial agent is simply taken and sprayed on cut stems to carry out treatment.

Description

technical field [0001] The invention belongs to the technical field of tobacco additives, in particular to a method for treating tobacco stems with micrococcus acidophilus and improving the aroma. Background technique [0002] Tobacco is a plant of the genus Nicotiana in the family Solanaceae. The tobacco stem is the thick and hard vein of the tobacco leaf, accounting for about 25-30% of the leaf weight. Tobacco stems are by-products of the tobacco industry and are mostly disposed of at present. my country is a big tobacco country, and hundreds of thousands of tons of tobacco stem resources are discarded every year, which not only causes environmental pollution, but also wastes natural resources. Studies have shown that the types of components contained in tobacco stems are basically the same as those of tobacco leaves. After adding expanded shredded stems to the formula, due to its high filling value, the amount of shredded tobacco in cigarettes can be reduced, which not ...
