Embodiment 1

[0026] Embodiment 1, a kind of method utilizing natural yeast to quickly age tobacco leaves is characterized in that the method comprises the following steps:

[0027] (1) Remove stalks, green miscellaneous fruits, moldy and rotten fruits and other sundries from 10 kg of selected mature "black grape" grapes (produced in Yunnan) whose skin color is black and purple, covered with white frost, and taste sweet but not sour, and then Crush the intact grape grains and put them into a 10-liter clean glass jar, the amount of which should not exceed two-thirds of the capacity of the container, and cover the lid (not sealed); place the glass jar on 24-28 ℃ room environment, natural fermentation for 48 hours, stirring once every 4-8 hours, stirring the floating grape skins into the juice;

[0028] (2) 48 hours after the grapes are put into the tank, when the temperature of the tank wall rises slightly and the air bubbles in the tank increase, the surrounding grape skins will roll and flo...

Embodiment 2

[0039] Embodiment 2, a kind of method utilizing natural yeast to quickly age tobacco leaves is characterized in that the method comprises the following steps:

[0040] (1) Remove stalks, green miscellaneous fruits, moldy and rotten fruits and other sundries from 10 kg of selected mature "black grape" grapes (produced in Yunnan) whose skin color is black and purple, covered with white frost, and taste sweet but not sour, and then Crush the intact grape grains and put them into a 10-liter clean glass jar, the amount of which should not exceed two-thirds of the capacity of the container, and cover with a lid (not sealed); place the glass jar on 24-28 ℃ room environment, natural fermentation for 48 hours, stirring once every 4-8 hours, stirring the floating grape skins into the juice;

[0041] (2) 48 hours after the grapes are put into the tank, when the temperature of the tank wall rises slightly and the air bubbles in the tank increase, the floating of the bubbles will drive the...

Embodiment 3

[0052] Embodiment 3, a kind of method utilizing natural yeast to quickly age tobacco leaves is characterized in that the method comprises the following steps:

[0053] (1) Remove 100 kg of mature "black grape" grapes (produced in Yunnan) from stems, green miscellaneous fruits, moldy and rotten fruits and other sundries, break the intact grape grains, put them into a 100-liter fermenter, and put them into The amount should not exceed two-thirds of the container capacity, cover the lid (not sealed), and control the environment of the tank at 26-28°C, ferment naturally for 48 hours, stir once every 4-8 hours, and The floating grape skins are stirred into the juice;

[0054] (2) After the grapes were put into the tank for 48 hours, the fermented product obtained in step (1) was filtered to remove large particles of impurities with a plate and frame filter, and the filtrate after the coarse filtration was collected, which was the natural yeast used;

[0055] (3) Place the natural ...

Abstract

The invention provides a method which achieves fast ageing of tobacco leaves by means of unartificial yeast. The unartificial yeast is obtained by using wine grapes as a raw material, using microorganisms in the wine grapes and sugar in fruit pulp and conducting natural fermentation at 24-28 DEG C; the unartificial yeast is subjected to cold storage in an environment at 1-5 DEG C for activity remaining, and after resuscitation and ripening, the unartificial yeast is applied to the tobacco leaves which are subjected to conditioning according to the dosage of 5.0-8.0%; ageing is conducted on theleaves in an environment with the relative humidity of 70-80% and the temperature of 25-28 DEG C and an environment with the relative humidity of 70-80% and the temperature of 28-32 DEG C respectively, wherein each stage lasts 36-40 hours, so that the tobacco leaf alcoholization requirements are met, and then fast ageing of the tobacco leaves is achieved. The method is concise and easy to control, fermentation starts quickly, the ageing cycle is short, and the method is a new path for economic and efficient tobacco leaf ageing.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a method for rapidly aging tobacco leaves by using natural yeast. Background technique [0002] Flue-cured tobacco is one of the important pillar industries in my country. However, due to cultivation and baking, the current domestic flue-cured tobacco generally has problems with high or unbalanced macromolecular components such as starch and protein, which affects the internal quality of tobacco leaves, especially the aroma of tobacco leaves. and smell. [0003] A large part of the transformation and decomposition of macromolecular compounds in tobacco leaves depends on the action of enzymes, which always exist from the growth, curing, and aging of tobacco leaves. In the process of tobacco leaf processing, in order to make up for the deficiency caused by improper growth or modulation of tobacco leaves, the tobacco leaves can be treated by adding protease, amylase, etc. to degrade...
