Problems solved by technology

[0010] However, the tobacco leaves fermented by a certain type or a certain type of microorganisms have a slightly monotonous aroma, and the aroma is not rich enough. There is no natural rich aroma brought by different fermentations or reactions during the natural fermentation process with seasonal temperature changes.
[0011] At present, there are many biological fermentation methods in the method of aging tobacco leaves, but for the method of improving the quality of tobacco sheets, there are now many methods of applying various extracts to the surface of the sheet or coating the surface of the sheet to improve the quality, and No biological fermentation method has been used

Embodiment 1

[0023] Place the lactic acid bacteria and golden flower strains at a temperature of 20°C for 4 hours, then inoculate the lactic acid bacteria and golden flower strains on the activated medium according to the inoculation amount of 1% of the weight of the medium, and cultivate them at 20°C. For 48 hours, the bacterial seeds were prepared; the lactic acid bacteria and the golden flower bacteria were mixed according to a certain ratio, so that the number of live bacteria of the lactic acid bacteria was 5×10 7 cFu / ml, the number of live bacteria of Jinhua bacteria is 4×10 7 cFu / ml.

[0024] Take 1Kg of tobacco flakes and put them into the warehouse of aged tobacco leaves, evenly disperse the tobacco flakes, and evenly spray the compound microbial bacterial liquid of lactic acid bacteria and golden flower bacteria on the surface of the tobacco flakes. The amount of bacterial liquid applied is 1% of the weight of the tobacco flakes % fermented for 5 days, and the temperature was co...

Embodiment 2

[0033] Place the lactic acid bacteria and golden flower strains at a temperature of 30°C for 2 hours, then inoculate the lactic acid bacteria and golden flower strains on the activated medium according to the inoculation amount of 3% of the weight of the medium, and cultivate them at 30°C. After 24 hours, the bacteria seeds were prepared; the lactic acid bacteria and the golden flower bacteria were mixed according to a certain ratio, so that the number of live bacteria of the lactic acid bacteria was 1×10 7 cFu / ml, the number of live bacteria of Jinhua bacteria is 1×10 7 cFu / ml.

[0034] Take 1Kg of tobacco flakes and put them into the warehouse of aged tobacco leaves, evenly disperse the tobacco flakes, and evenly spray the compound microbial bacterial liquid of lactic acid bacteria and golden flower bacteria on the surface of the tobacco flakes. % Fermented for 9 days, the temperature was controlled at 32°C. Finally, the tobacco sheets are naturally stored at room temperat...

Embodiment 3

[0043] Place the lactic acid bacteria and golden flower strains at a temperature of 35°C for 3 hours, then inoculate the lactic acid bacteria and golden flower strains on the activated medium according to the inoculation amount of 5% of the weight of the medium, and cultivate them at 25°C. For 48 hours, the bacterial seeds were prepared; the lactic acid bacteria and the golden flower bacteria were mixed according to a certain ratio, so that the number of live bacteria of the lactic acid bacteria was 3×10 8 cFu / ml, the number of live bacteria of Jinhua bacteria is 5×10 8 cFu / ml.

[0044] Take 1Kg of tobacco flakes and put them into the warehouse of aged tobacco leaves, spread the tobacco flakes evenly, and evenly spray the composite microbial bacterial liquid of lactic acid bacteria and golden flower bacteria on the surface of the tobacco flakes, the amount of bacterial liquid applied is 5% of the weight of the tobacco flakes %, fermented for 6 days, and the temperature was cont...

Abstract

The invention provides a method for improving the quality of tobacco sheets by compound microbial fermentation. The method comprises the steps of evenly spraying a compound microbial bacteria solution of lactic acid bacteria and golden-flower fungus onto the surfaces of the tobacco sheets, wherein the application amount of the bacteria solution is 1-5%; fermenting for 5-10 days, and controlling the temperature to be 25-45 DEG C; naturally storing the tobacco sheets for 1-4 weeks at the room temperature of 10-30 DEG C. After the tobacco sheets are fermented by using the compound microorganism of the lactic acid bacteria and the golden-flower fungus, components such as cellulose, protein and pectin which are adverse to cigarette smoking quality in the tobacco sheets are effectively decomposed; furthermore, the quality of the tobacco sheets is obviously improved, the irritation of the tobacco sheets is reduced, and the tobacco sheets have sour aroma and aging aroma of tobaccos and are rich and natural in aroma.

Description

technical field [0001] The invention relates to a biological fermentation technology, in particular to a method for improving the quality of tobacco flakes through compound microbial fermentation. Background technique [0002] Tobacco flakes are made from raw materials such as tobacco powder, tobacco leaf fragments, tobacco stems or low-grade tobacco leaves produced during the production and processing of ordinary tobacco leaves, and are reprocessed by papermaking methods, also known as reconstituted tobacco leaves or homogeneous tobacco leaves. Tobacco flakes are therefore different from normal tobacco leaves in that they do not grow naturally, and their smoking quality is generally poor. [0003] There are three kinds of tobacco leaf fermentation processes that are mostly used at present: (1) natural fermentation, (2) artificial fermentation, and (3) stacking fermentation. [0004] Natural fermentation (also known as natural alcoholization or aging) is the mildest ferment...
