Method for alcoholizing and fermenting fresh and sweet type flue-cured tobacco leaves using biotechnology

Abstract

The invention belongs to the field of light industry tobacco and specifically relates to a method for reducing alcoholic fermentation time of flue-cured tobacco leaves by using biological technology to add tobacco leaf alcoholization fermentation beneficial bacteria in the process of alcoholic fermentation of flue-cured tobacco leaves, and improving tobacco leaf mellow feeling, soft feeling, eating taste, reducing burning taste and green odor. According to the method, by adding selected tobacco leaf alcoholization aroma enhancement and quality promotion beneficial bacteria to alcoholized and fermented tobacco leaves and by controlling the temperature, humidity and other conditions during the alcoholization fermentation process in stages, at the end of the alcoholization, the total sugar oftobacco leaves is increased to 37.42%, and the nitrogen content is decreased to 1.56%; product evaluation results: the aroma of tobacco leaves is improved, the sweetness is improved, the green gas isimproved, the aftertaste is refreshing, the smoke is soft, the odor is mellow, and the effect of flavor enhancement and quality improvement is remarkable.

Description

technical field [0001] The invention belongs to the field of light industrial tobacco, and specifically relates to a method for alcoholizing and fermenting flue-cured tobacco leaves of "clean, sweet and fragrant" type by using biotechnology. Background technique [0002] Alcoholic fermentation of tobacco is the most core and important step in the process of flue-cured tobacco processing. It determines the quality of a tobacco, and a good fermentation process can greatly improve the quality of tobacco leaves. Unfermented tobacco has the most prominent raw green miscellaneous gas and pungent odor, without the characteristic aroma of fermented tobacco, monotonous aroma, and insufficient aroma, so it cannot be directly used for production. After the fermentation treatment, the tobacco green miscellaneous gas and irritation are reduced, and the tobacco aroma is revealed, so the tobacco leaves must be fermented before they can be used for production. At present, the tobacco ferme...
