Problems solved by technology

This invention also cannot be applied evenly because the water consumption is too small, and the long time of 6-10 months will easily inactivate the enzyme preparation and easily lead to mildew of the tobacco leaves, so it is difficult to really apply

Embodiment 1

[0015] A method for improving the sensory quality of tobacco leaves by using a compound enzyme preparation, the relevant process steps are as follows:

[0016] (1) The cellulase, pectinase and protease required for the production of relevant strains are used for fermentation. After the enzyme preparation is obtained, it is prepared into a treatment solution. Add 5‰ trisodium citrate, 5‰ citric acid, 10‰ cellulase, 8‰ pectinase, 6‰ protease, 3‰ biacetyl, 3‰ FeSO in the pure water frozen to 4℃ 4 .

[0017] (2) Spray treatment solution: Spray the prepared treatment solution evenly on the surface of tobacco leaves with 50% mass (1000g tobacco leaves sprayed with 500ml compound enzyme preparation), and turn the tobacco leaves when spraying to make the spray even and keep the tobacco leaves loose.

[0018] (3) Constant temperature and humidity reaction: Put the tobacco leaves sprayed with the treatment liquid in a sealed container, adjust the reaction temperature to 48°C, and the...

Embodiment 2

[0028] To treat shredded tobacco with compound enzyme preparation, the relevant process steps are as follows:

[0029] (1) Obtain biological enzymes and prepare treatment solutions: For a small amount of research and treatment, you can directly purchase relevant biological enzymes, and for industrialization, you can build large-scale fermentation facilities by yourself, and use relevant strains to ferment and produce the required cellulase, pectinase and protease. After the enzyme preparation is obtained, it is prepared into a treatment solution. Add 4‰ trisodium citrate, 4‰ citric acid, 8‰ cellulase, 5‰ pectinase, 4‰ protease, 2‰ biacetyl, 2‰ FeSO in the pure water frozen to 4℃ 4 .

[0030] (2) Spray treatment solution: Spray the prepared treatment solution with 28% mass (1000g tobacco leaves sprayed with 280ml compound enzyme preparation) evenly on the surface of tobacco leaves, and turn the tobacco leaves when spraying to make the spray even and keep the tobacco leaves lo...

Embodiment 3

[0039] To treat shredded tobacco with compound enzyme preparation, the relevant process steps are as follows:

[0040] (1) The cellulase, pectinase and protease required for the production of relevant strains are used for fermentation. After the enzyme preparation is obtained, it is prepared into a treatment solution. Add 1‰ trisodium citrate, 1‰ citric acid, 4‰ cellulase, 3‰ pectinase, 2‰ protease, 1‰ biacetyl, 1‰ FeSO in the pure water frozen to 4℃ 4 .

[0041] (2) Spray treatment liquid: Spray the prepared treatment liquid evenly on the surface of tobacco leaves with 8% mass (1000g cut tobacco sprayed with 80ml compound enzyme preparation), and turn the tobacco leaves when spraying to make the spray even and keep the tobacco leaves loose.

[0042] (3) Constant temperature and humidity reaction: Put the tobacco leaves sprayed with the treatment liquid in a sealed container, adjust the reaction temperature to 30°C, the ambient humidity to 50%, and the reaction time to be 2...

Abstract

The invention relates to a method for improving sensory quality of tobacco leaves by using a compound enzymic preparation. According to the method, the compound enzymic preparation containing cellulose, pectinase, protease, FeSO4, biacetyl, citric acid, trisodium citrate and water is used to degrade celluloses and pectin in tobacco leaves. The compound enzymic preparation has the advantages of reducing the content of harmful ingredients in cigarette smoke such as phenol, HCN, BaP and NNK, reducing the irritability and strength of the cigarette smoke, enriching fragrance, and lightening miscellaneous gas, so that the cigarette smoke is relatively fine, and the sensory quality of the tobacco leaves is improved.

Description

technical field [0001] The invention relates to a method for improving the sensory quality of tobacco leaves by using a compound enzyme preparation, which belongs to the field of tobacco leaf processing and the field of biological enzyme preparations. technical background [0002] The use of modern biotechnology to degrade the harmful components of tobacco leaves (mainly the precursors of harmful components in smoke) is an effective way to reduce the harm of cigarettes, and is currently attracting more and more attention from researchers. The content of cellulose, lignin, hemicellulose, pectin and other components accounts for about 28% of the total dry matter of tobacco leaves. They rarely change during tobacco processing. These substances have great influence on the internal quality and style characteristics of tobacco. There are adverse effects. They produce irritating pyrolysis products when burning and inhaling, causing smokers to choke. Components such as cellulose an...
