Embodiment 1

[0062] Influence of the curing process of the present invention on the content of TSNAs in NC102 tobacco leaves with different maturity

[0063] S100: Fresh NC102 flue-cured tobacco leaves of different maturity levels collected in Jiuxi Town, Jiangchuan District, Yuxi City, Yunnan Province. The mature fresh tobacco leaves have main veins that turn white and shiny, and branches that turn green and white. The leaves are greenish yellow or light yellow, and most of the hairs After falling off, it has the characteristics of rich e-liquid after touching it. Tobacco leaves picked and roasted 15 days before mature tobacco leaves were picked and roasted were regarded as underripe tobacco leaves. Tobacco leaves picked and roasted 15 days after mature tobacco leaves were picked and roasted were regarded as overripe tobacco leaves.

[0064] S200: classify the above harvested fresh tobacco leaves according to the amount of 90-110 pieces / stem for weaving and weaving the stems.

[0065] S...

Embodiment 2

[0079] Influence of spraying ascorbic acid solution of the present invention on relative conductivity and MDA content of NC102 tobacco leaves with different maturity after curing

[0080] According to Example 1, the changes in the relative electrical conductivity and MDA content of tobacco leaves with different maturity levels were measured at the end of the early yellowing stage and the late yellowing stage.

[0081] Table 3 Changes of relative conductivity and malondialdehyde content of NC102 flue-cured tobacco with different maturity (roasted in Hongyan Town, Midu County)

[0082]

[0083] It can be seen from Table 3 that after being treated with ascorbic acid solution, the changes in the relative conductivity of flue-cured tobacco leaves with different maturity levels are significantly different, and the content of MDA in the leaves is also significantly different, among which T4 and T5 treatments can reduce the relative conductivity and content of malondialdehyde, and ...

Embodiment 3

[0084] Example 3 Effect of the present invention's curing process on the content of TSNAs in KRK26 tobacco leaves with different maturity

[0085] S100: KRK26 flue-cured fresh tobacco leaves of different maturity levels in Xiaguan Town, Dali Prefecture, Yunnan Province. The mature fresh tobacco leaves have main veins that turn white and shiny, and branches that turn green and white. The leaves are greenish yellow or light yellow, and most of the hairs fall off. After that, it has the characteristics of rich smoke oil. Tobacco leaves picked and roasted 15 days before mature tobacco leaves were picked and roasted were regarded as underripe tobacco leaves. Tobacco leaves picked and roasted 15 days after mature tobacco leaves were picked and roasted were regarded as overripe tobacco leaves.

[0086] S200: classify the above harvested fresh tobacco leaves according to the amount of 90-110 pieces / stem for weaving and weaving the stems.

[0087] S300: Spray and inoculate evenly on ...

Abstract

The invention relates to a substance for reducing TSNAs of flue-cured tobaccos with different maturity degrees, an application and a baking process. The substance is an ascorbic acid solution, and the mass percentage concentration of the ascorbic acid solution is 0.5%, 1%, 1.5%, 2% and 2.5%. The substance provided by the invention can reduce TSNAs in the flue-cured tobacco. According to the invention, the ascorbic acid solution is applied to the flue-curing process of the tobacco leaves with different maturity degrees for the first time to reduce the TSNAs content in the flue-cured tobaccos with different maturity degrees, the total TSNAs content in the flue-cured tobaccos with different maturity degrees is reduced by 23%-29%, NNK, NNN and NAT are reduced by 21%-27%, 24%-30% and 25%-32% respectively, and the effect is very remarkable. Aiming at the tobacco leaves with different maturity degrees, the degradation rate of the TSNAs is improved by reasonably matching and using the ascorbic acid solution so that the quality of the tobacco leaves is remarkably improved, and the harm of the TSNAs to human health and living environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of tobacco curing, in particular to a substance for reducing TSNAs of flue-cured tobacco with different maturity, including the application of the substance and the technical field of curing technology. Background technique [0002] Nicotine is highly toxic, permeable to biofilms, stable in chemical structure and not easy to degrade, and is an important precursor of carcinogen tobacco-specific nitrosamines (TSNAs). When nicotine reaches the brain, it causes the release of adrenaline, so it becomes addictive to nicotine, and 600,000 people die each year from the nicotine in smoking and the polluting particles it leaves behind. As the largest tobacco planting and processing country in the world, my country urgently needs to solve the harm caused by nicotine in tobacco. Tobacco-specific nitrosamines (TSNAs) are one of the main harmful substances that affect human health. A large number of studies have shown t...
