A method of alcoholizing and fermenting "sweet and fragrant" flue-cured tobacco leaves using biotechnology

Abstract

The invention belongs to the field of light industrial tobacco, and specifically relates to a method of using biotechnology to add tobacco leaf alcoholizing fermentation beneficial bacterial strains in the alcoholizing fermentation process of flue-cured tobacco leaves to reduce the alcoholizing fermentation time of flue-cured tobacco leaves, improve the mellowness, softness, and taste of tobacco leaves, and reduce burnt taste and blueness. The smelly way. In this method, the selected microorganisms beneficial to alcoholizing and fermenting tobacco leaves are added to the alcoholizing and fermenting tobacco leaves, and the temperature, humidity and other conditions in the alcoholizing and fermenting process are controlled in stages, and the total sugar of the tobacco leaves after alcoholizing is increased to 37.42%. Nitrogen content dropped to 1.56%. Smoking evaluation results: the aroma of tobacco leaves is improved, the sweetness is improved, green miscellaneous gas is improved, the aftertaste is refreshing, the smoke is soft, the smell 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...
