Problems solved by technology

[0003] Biotechnology, especially the application of microbial fermentation and enzyme technology in tobacco has gradually become a hot topic. The main content of the research includes isolating some beneficial bacteria from the surface of tobacco leaves, and applying them to the surface of tobacco through enrichment culture (Tobacco Science and Technology, 1998 (1) ), and cellulase is also used to partially degrade the lignin and cellulose of tobacco stems (U.S.pat.3747608), so as to soften the tobacco stems to facilitate the processing of shredded stems and reduce the woody gas-like impurities of shredded stems, and use aroma-producing microorganisms to ferment and produce Tobacco spices (Tobacco Science and Technology, 1997, (1)), microorganisms are applied to natural alcoholized tobacco, because the moisture content of natural alcoholized tobacco leaves is 11-13%, the growth of microorganisms is inhibited, and the effect is poor. In addition, the amount of microorganisms is difficult to control, which may cause Changes in the quality of finished cigarettes during storage and sale

Embodiment 1

[0011] Take 1000 grams of Yunnan flue-cured tobacco C 3 F threshed red-cured tobacco leaves, the water content is 12%, weigh 0.6 grams of mixed enzyme, 0.1 grams of pyruvate, 0.1 grams of tryptophan and leucine, 0.01 grams of zinc sulfate, manganese sulfate, magnesium carbonate, potassium tartrate 1 gram, dissolved in 5ml of distilled water, sprayed into the tobacco leaves, then packaged and put into the warehouse for alcoholization. The sample treated with 6 months of aging and the untreated sample of the same grade after 3 years of natural aging were taken out and cut into shreds to roll sample cigarettes, and the moisture was balanced for 24 hours at a relative humidity of 60% for sensory evaluation. The results of smoking evaluation showed that the smoke quality of the enzyme-treated sample was better than that of the control, showing a beautiful aroma, delicate smoke, and elimination of irritation and miscellaneous gas.

Embodiment 2

[0013] Take 1000 grams of Yunnan flue-cured tobacco B 3 F threshed red-cured tobacco leaves, the moisture content is 11%, weigh 1.5 grams of mixed enzyme, 0.25 grams of pyruvate, 0.2 grams of tryptophan and leucine, 0.03 grams of zinc sulfate, manganese sulfate and magnesium carbonate, potassium tartrate 3 grams, dissolved in 10ml of distilled water, sprayed into the tobacco leaves, then packaged and put into the warehouse for alcoholization. The sample treated with 6 months of aging and the untreated sample of the same grade after 3 years of natural aging were taken out and cut into shreds to roll sample cigarettes, and the moisture was balanced for 24 hours at a relative humidity of 60% for sensory evaluation. The results of smoking evaluation showed that the smoke quality of the enzyme-treated sample was better than that of the control, showing that the smoke became more alcoholic, and the irritation and miscellaneous gas were significantly reduced.

Embodiment 3

[0015] Take 1000 grams of Yunnan flue-cured tobacco X 1 F threshed red-cured tobacco leaves, moisture content is 13%, weigh 3 grams of mixed enzyme, 0.4 grams of pyruvate, 0.3 grams of tryptophan and leucine, 0.05 grams of zinc sulfate, manganese sulfate, magnesium carbonate, potassium tartrate 5 grams, dissolved in 10ml of distilled water, sprayed into the tobacco leaves, then packaged and put into the warehouse for alcoholization. The sample treated with 6 months of aging and the untreated sample of the same grade after 3 years of natural aging were taken out and cut into shreds to roll sample cigarettes, and the moisture was balanced for 24 hours at a relative humidity of 60% for sensory evaluation. The smoke evaluation results showed that the smoke quality of the enzyme-treated sample was better than that of the control, which showed that the aroma concentration increased, and the irritation and miscellaneous gas were significantly reduced.

Abstract

A biologic enzyme process for promoting natural alcoholization of baked tobacco leaves is characterized by that the proteinase and pectinase are used to treat tobacco leaves for degradating the protein and pectin in them and the promoters of biochemical reaction, such as pyruvic acid, tryptophan, leucine and metallic ions [Mn(2+), Zn(2+), Mg(2+) and K(+)] use used to activate the activity of enzyme contained in tobacco leaves. Its advantages are short period shortened from 2-3 years to 6 months and high quality of tobacco.

Description

technical field [0001] The invention relates to the application of bioenzyme technology and bioactive catalytic substances in the natural aging process of tobacco. The international patent classification belongs to A24B. Background technique [0002] Tobacco is a special economic crop for smoking, and its use value depends on its quality. Flavor is an important element of tobacco leaf quality. High-quality tobacco leaves require pure aroma, sufficient aroma, mellow taste and comfortable aftertaste. It is a complex system engineering from planting to rolling into cigarette products, during which it has gone through many physiological, biochemical, technological and other processes related to the flavor and taste of tobacco leaves, including the alcoholization of tobacco leaves. Threshing and re-baking is the basic method to solve the defects in the quality of harvested tobacco leaves. The first-cured tobacco (also known as raw tobacco) purchased from the tobacco station is t...
