Abstract

The invention discloses a microbial agent for tobacco and a preparation method and application of the microbial agent, and belongs to the field of application of the microbial technology. The microbial agent formed by candida utilis and bacillus subtilis is evenly sprayed to tobacco leaves and cut tobacco, cellulose, hemicelluloses, pectin, protein, starch and other harmful macromolecular precusor substances in the tobacco can be effectively degraded, therefore, the aim of reducing free radicals, polycyclic aromatic hydrocarbon, nitrogen nitrosamine and other main harmful ingredients in tar of cigarettes is achieved, and tobacco quality is improved.

Description

technical field [0001] The invention relates to the field of microbial technology application, in particular to a method for degrading harmful substances in tobacco by adding microbial agents. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] The chemical components and factors affecting the quality and flavor of tobacco are extremely complex, but the harmful components that have not been effectively degraded by natural or artificial fermentation are mainly cell wall components that account for 28% of the dry weight of tobacco itself: cellulose, hemicellulose, lignin , pectin, they seldom undergo degradation changes during the whole storage, alcoholization and processing of tobacco. No matter the tobacco itself, the microorganisms in the fermentation of tobacco or the biologically active enzymes have no ability t...
