Problems solved by technology

[0006] The aqueous solution of reconstituted tobacco leaves was used as the substrate, and Penicillium citrinum ferulic acid esterase, xylanase, glucose oxidase, catalase, and phenol oxidase were used to act synergistically, and Bacillus methylotrophicus (VJ4-1 ) transformation, decomposes lignin, cellulose, protein and other macromolecular irritating substances in reconstituted tobacco leaves, releases ferulic acid, and converts ferulic acid into flavor precursors such as vanillin, so that the produced reconstituted tobacco leaves reduce irritation, Reduce green miscellaneous gas, beautiful aroma, slightly milky aroma, improve the sensory quality of reconstituted tobacco leaves, which has not been reported yet

Abstract

The invention provides a method for improving the sensory quality of reconstituted tobaccos through biotransformation. The method comprises the following steps that 1, strain activation is performed: bacillus methylotrophicus (VJ4-1) is inoculated to an oblique-plane culture medium and then is inoculated to a seed culture medium, and a seed culture solution is prepared through transfer; 2, composite biotransformation pretreatment is performed: in a reconstituted tobacco extraction process, the seed culture medium in the step 1 is inoculated to a reconstituted tobacco water solution, penicillium citrinum feruloyl esterase, xylanase, glucose oxidase, catalase, phenol oxidase and other complex enzymes are added, stirring and even mixing are performed, and a reconstituted tobacco biotransformation solution is obtained through fermentation; 3, the reconstituted tobaccos are produced through a conventional reconstituted tobacco process, the temperature exceed 75 DEG C in the process, the enzymes and bacteria are inactivated, and the reconstituted tobaccos are obtained through rolling. The produced reconstituted tobaccos with the aroma quality improved by adopting a biotechnology have good aroma with a slight milk flavor, the irritation is reduced, green miscellaneous smell is decreased, and the sensory quality of the reconstituted tobaccos is improved.

Description

technical field [0001] The invention relates to the field of tobacco industry, in particular to a method for improving the sensory quality of reconstituted tobacco leaves through biotransformation. Background technique [0002] Reconstituted tobacco leaves are mainly composed of tobacco powder, chips, tobacco stems or low-grade tobacco leaves with adhesives and other additives. Tobacco dust, chips, and tobacco stems are by-products of the tobacco industry, and were mostly disposed of in the past. my country is a big tobacco country, and hundreds of thousands of tons of tobacco dust, debris, and 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 ingredients contained in tobacco powder, chips, and tobacco stems are basically the same as those of tobacco leaves, but there are flavor defects such as heavy miscellaneous gas, strong irritation, and unpleasant taste...
