Problems solved by technology

In the process of traditional flue-cured tobacco carbon dioxide expansion treatment, the aroma is enhanced by adding feed liquid. Due to the loss of aroma substances after low-temperature carbon dioxide liquid immersion extraction and hot air high-temperature expansion treatment, the sensory quality of shredded tobacco is not improved by adding feed liquid. Significantly improved, and the feed liquid will be deposited in the carbon dioxide liquid recovery pipeline, which will affect the performance of the equipment

Abstract

The invention discloses a method for improving the quality of carbon dioxide expanded tobacco shreds by using a perfumed compound microbiological agent. The method includes the following steps that tobacco leaves / leave groups are subjected to slicing, humidifying and shredding, a composite microbial preparation is sprayed on tobacco shreds, and after constant-temperature and constant-humidity fermentation, carbon dioxide expansion process of the tobacco shreds is conducted, wherein the perfumed compound microbiological agent is composed of bacillus subtilis Y1, bacillus subtilis X7 and bacillus subtilis X8 at the mass ratio of (0.001-1):(0.001-1):(0.001-1), and the preservation numbers, in the China general microbiological culture collection center, of the three kinds of bacillus subtilis are CGMCC No.13602, CGMCC No.13603 and CGMCC No.13604 respectively. The method can obviously improve the sensory quality of carbon dioxide expanded tobacco shreds, the sensory quality of cigarettes can be improved and the content of harmful components is reduced.

Description

technical field [0001] The invention belongs to the technical field of cigarette production technology, and relates to a method for improving the quality of carbon dioxide-expanded shredded tobacco by using an aroma-imparting compound microbial preparation. technical background [0002] With my country's accession to the World Trade Organization and the signing of the "Framework Convention on Tobacco Control", the tobacco industry and consumers have paid more and more attention to smoking and health issues. my country is a country dominated by flue-cured tobacco cigarettes. Compared with foreign blended cigarettes, Chinese flue-cured tobacco cigarettes contain relatively higher levels of harmful substances such as tar. [0003] Carbon dioxide shredded tobacco expansion technology is a new process and new technology introduced in my country in recent years, which plays an important role in reducing the harm and tar of cigarettes. The main principle of carbon dioxide shredded...
