Embodiment 1

[0014] 1) Tea extract: take black tea leaves, add distilled water, heat and reflux for extraction for 2 hours according to the ratio of tea leaves to water to liquid: 1:8, then leave the extract to cool and then filter through a filter cloth to obtain tea extract;

[0015] 2) Lactic acid bacteria fermentation: use tea extract as a substrate, ferment it in an aseptic airtight state, the conditions of fermentation are: the volume of sucrose added is 6% of the volume of tea extract, and the inoculum volume of lactic acid bacteria is 6% of the volume of tea. 1.0% of the extract, the fermentation temperature is 28°C, and the fermentation time is 3 days;

[0016] 3) Post-treatment of the fermented product: After filtering to remove large particles of impurities, concentrate the filtrate for the first time at -0.01~-0.1Mpa at 80°C, add 4 times the volume of alcohol solution with a mass fraction of 95%, and dissolve it back at -20°C Cooling and sedimentation treatment for 18 hours; us...

Embodiment 2

[0018] 1) Tea extract: take green tea leaves, add distilled water, heat and reflux for extraction for 1 hour according to the ratio of tea to water to liquid: 1:6, then let the extract stand for cooling and then filter it with a filter cloth to obtain tea extract;

[0019] 2) Lactic acid bacteria fermentation: use tea extract as a substrate, ferment it in an aseptic airtight state, the conditions of fermentation are: the volume of sucrose added is 6% of the volume of tea extract, and the inoculum volume of lactic acid bacteria is 6% of the volume of tea. 4.0% of the extract, the fermentation temperature is 37°C, and the fermentation time is 2 days;

[0020] 3) Post-treatment of the fermented product: After filtering to remove large particles of impurities, concentrate the filtrate for the first time at -0.01 ~ -0.1Mpa at 80°C, add 3 times the volume of alcohol solution with a mass fraction of 95%, and redissolve at -20°C Cooling and sedimentation treatment for 20 hours; filter...

Embodiment 3

[0022] 1) Tea extract: take oolong tea leaves, add distilled water, heat and reflux for extraction for 3 hours according to the ratio of tea and water to liquid of 1:10, then leave the extract to cool and then filter through a filter cloth to obtain tea extract;

[0023] 2) Lactic acid bacteria fermentation: use tea extract as a substrate, ferment it in an aseptic airtight state, the conditions of fermentation are: the volume of sucrose added is 6% of the volume of tea extract, and the inoculum volume of lactic acid bacteria is 6% of the volume of tea. 2.0% of the extract, the fermentation temperature is 30°C, and the fermentation time is 1 day;

[0024] 3) Post-treatment of the fermented product: After filtering to remove large particles of impurities, concentrate the filtrate for the first time at -0.01 to -0.1Mpa at 80°C, add 5 times the volume of alcohol solution with a mass fraction of 95%, and redissolve at -20°C Cooling and sedimentation treatment for 24 hours; use filt...

Abstract

The invention provides a preparation method of a lactobacillus-fermented tea leaf extract for cigarettes. The preparation method comprises the following steps: (1) mixing tea leaves with water at a material-liquid ratio of 1 to (6-10), carrying out heating reflux for 1-3 hours, cooling, and filtering to obtain a tea leaf extract; (2) fermenting the tea leaf extract obtained in the step (1) with lactobacillus and sucrose at 28-37 DEG C for 3 days to obtain a fermented product, wherein the volume of the lactobacillus is equal to 1.0%-3.0% of that of the tea leaf extract, and the volume of the added sucrose is 6% of that of the tea leaf extract; and (3) filtering the fermented product, and concentrating the filtered fermented product so as to obtain the lactobacillus-fermented tea leaf extract for the cigarettes. By adding the lactobacillus-fermented tea leaf extract for the cigarettes, the cigarettes have relatively rich flavors and relatively obvious sweetness, furthermore, the fresh and sweet fragrances are increased, the elegancy is relatively high, and the irritation is decreased; the preparation method has the very strong practicability.

Description

technical field [0001] The invention relates to a method for preparing tobacco spices, in particular to a method for preparing tobacco tea extract fermented by lactic acid bacteria. Background technique [0002] In tobacco products, the aroma and taste of tobacco are very important. Adding spices is a key link in the cigarette process, and it is also one of the effective means to improve the product style and improve the quality of cigarette aroma. It can provide consumers with some aroma and Cigarette products with satisfying taste. At present, most of the tobacco flavors added to tobacco in my country are prepared by traditional methods, that is, mixed with natural extract monomers and synthetic monomers. The aroma is monotonous, the improvement of tobacco is insufficient, and the effect of improving the smoking quality of cigarettes is not obvious. [0003] Tea leaves are rich in aroma substances. So far, about 700 kinds of tea aroma substances have been isolated and ide...
