Method for reducing content of nicotine in flue-cured tobacco leaves

Abstract

The invention provides a method for reducing the content of nicotine in flue-cured tobacco leaves. Within two hours after flue-cured tobaccos are topped, the topped sections of the flue-cured tobaccos are smeared with 1.0-2.0 ml of a nicotine signal regulating substance solution, and covered with round paper patches with the diameter being 2.5 cm; according to the using method, 1, the nicotine signal regulating substance solution is used instantly after being prepared, wherein 1000 ml of purified water is mixed with 8.0-10.0 g of glucose oxidase, 2.0-3.0 g of vitamin C, 3.0-5.0 g of vitamin E, 300-500 mg of vitamin E, 5 g of sorbitol, 50 g of glycerol and 10 g of magnesium sulfate heptahydrate; according to the different soil types, flue-cured tobacco varieties and the nitrogen fertilizer application level, the different smearing amounts of the nicotine signal regulating substance solution are determined. According to the method for reducing the content of the nicotine in the flue-cured tobacco leaves, the synthetic amount of the nicotine in flue-cured tobacco roots can be reduced, the content of the nicotine in the tobacco leaves of all parts is reduced, especially, the content of nicotine in the tobacco leaves of the upper portion is reduced, coordination of chemical ingredients of the tobacco leaves is improved, industrial usability of the tobacco leaves is improved, and the method is particularly suitable for being applied and popularized in high-grade cigarette brand base units.

Description

technical field [0001] The invention relates to the production and use of flue-cured tobacco after topping with an antioxidant signal substance, in particular to a method for reducing the nicotine content of flue-cured tobacco leaves. Background technique [0002] Due to the topping agricultural operation measures of flue-cured tobacco in my country, the nicotine synthesis ability of tobacco roots has been significantly improved, and the distribution and accumulation of nicotine in different parts of the tobacco leaves has increased rapidly, especially the high content of nicotine in the upper leaves, resulting in a change in the coordination of the internal chemical components of the tobacco leaves. Poor, the sensory evaluation of tobacco leaves has enhanced pungency, and the usability of tobacco leaves has deteriorated. Under the background of reducing tar and harm of cigarettes in my country, reducing the nicotine content of tobacco leaves, especially the nicotine content ...

Problems solved by technology

[0003] Existing methods for reducing the nicotine content of tobacco leaves generally use reducing the amount of nitrogen fertilizer used, reducing the number and height of cultivating soil, or using methods such as cutting branches and leaving more leaves. Although this method can reduce the nicotine content of tobacco leaves to a certain extent, But at the same time, it also obviously reduces the internal quality and economic yield of tobacco leaves, especially the effect on reducing the nicotine content of upper tobacco leaves is not particularly obvious

Through hormone regulation, the nicotine content of tobacco leaves can also be reduced, but the leaves of tobacco leaves are enlarged and thickened, with poor combustibility, and the quality of sensory evaluation is difficult to be accepted by cigarette companies
