Embodiment 1

[0025] Example 1 strain screening

[0026] The coronoid saccharomyces strain of the present invention is isolated from Liubao tea produced in Wuzhou, Guangxi, and specifically comprises the following steps:

[0027] (1) Use enrichment medium to isolate microbial strains from Liubao tea, grind Liubao tea and add enrichment medium to cultivate and screen. The enrichment medium is: 1g K 2 HPO 4 ·3H 2 O, 0.5g MgSO 4 ·7H 2 O, 3g NH 4 NO 3 , 32gNaCl, 20g sucrose, 1000mL water, pH 6.0;

[0028] (2) The obtained microbial bacterium liquid is screened on the flat plate separation medium by the flat coating method, and after constant temperature cultivation, the bacterial colonies with large morphological differences are selected to be streaked and purified respectively until a single colony occurs, and the bacterial strain is obtained, kept, and used for future use; The plate separation medium is: 1g K 2 HPO 4 ·3H 2 O, 0.5g MgSO 4 ·7H 2 O, 3g NH 4 NO 3 , 32g NaCl, 20g suc...

Embodiment 2

[0032] Inoculate the bacterial strains screened in Example 1 of refrigerated preservation on the PDA slant medium with an inoculation needle, and place it at 30° C. to cultivate for 48 hours. ℃ inverted culture for 7 days.

[0033] The conidia culture medium is: 1g K 2 HPO 4 ·3H 2 O, 0.5g MgSO 4·7H 2 O, 3g NH 4 NO 3 , 32gNaCl, 20g sucrose, 15g agar powder, water 1000mL.

[0034] The conidia on the mycelium were washed off with sterile water, and the concentration of the spores was 10 6 -10 7 / mL of spore suspension.

[0035] Take 1 mL of the obtained spore suspension and dilute it with sterile water to obtain 5 g of the spore suspension, and mix well.

[0036] According to the proportion of 1wt% of the tea weight, the diluted spore suspension was evenly sprayed on 500 g of Liubao tea leaves (Guangxi), and then the tea leaves were placed at 28° C. for conventional composting and cultured for 48 hours to obtain Jinhua fungus tea leaves.

Embodiment 3

[0038] Add the chrysanthemum tea leaves prepared in Example 2 to 10Kg 2014 Guangxi Hezhou Zhongjusan C3F re-baked tobacco according to 0.2% of the weight of the tobacco leaves and mix evenly, and then seal the tobacco leaves and place them in a tobacco leaf storage warehouse for fermentation and alcoholization. The temperature of the tobacco leaf warehouse is room temperature, and the relative air humidity is ≤75%. Tobacco leaves were fermented and alcoholized for 60 days. The alcoholized tobacco leaves were evaluated and smoked by a panel of 7 experts. It was found that the alcoholic tobacco leaves had significantly reduced miscellaneous gases, decreased irritation, soft and delicate smoke, increased sweetness, increased tobacco aroma, and There is a tea aroma, and the quality and usability of the tobacco leaves are significantly improved.

Abstract

The invention belongs to the technical field of tobacco processing, and in particular relates to a preparation method of chrysanthemum tea leaves and a method for improving the quality of tobacco leaves by fermenting and recuring tobacco leaves with chrysanthemum tea leaves. The method for improving the quality of re-cured tobacco leaves described in the present invention firstly utilizes self-selected predominant bacterium S. coronis 502 to ferment Liubao tea leaves to obtain golden flower tea leaves, and then utilizes golden flower tea leaves to co-ferment with red-cured tobacco leaves. After the tobacco leaves are fermented, the miscellaneous gas in the smoke of the tobacco leaves is reduced, the irritation is reduced, the aroma quality is improved, the aroma volume is increased, and the sweetness is increased. The tobacco leaves have the fragrance of tea leaves, which effectively improves the quality and usability of the tobacco leaves.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a preparation method of chrysanthemum tea leaves and a method for improving the quality of tobacco leaves by fermenting and recuring tobacco leaves with chrysanthemum tea leaves. Background technique [0002] Tobacco leaf is the main raw material of the cigarette industry, and its quality determines the quality of cigarette products. The processing of tobacco leaves refers to the preparatory processing process of transforming tobacco leaves from agricultural products into industrial raw materials. Generally, it needs to go through the process of initial roasting and re-baking. The initial roasting process is to promote the physical and chemical properties of tobacco leaves under certain temperature and humidity conditions. , can initially improve the aroma and quality of tobacco leaves. The rebaking process is to adjust the moisture of the tobacco leaves f...
