Embodiment 1

[0021] This embodiment relates to the application of sodium phosphate buffer in reducing the amount of TSNAs released in cigarette smoke, which specifically includes the following steps:

[0022] Take 1kg of threshed and rebaked Burley tobacco, prepare a sodium phosphate buffer solution containing 13.5% disodium hydrogen phosphate and 0.6% sodium dihydrogen phosphate, and spray 200mL of sodium phosphate buffer evenly on the tobacco in the form of mist On the surface, make the sheet tobacco fully absorb the sodium phosphate buffer solution, so that the content of disodium hydrogen phosphate in the sheet tobacco is 3.0% (relative to the dry basis weight of tobacco leaves), and the content of sodium dihydrogen phosphate is 0.13% (relative to the dry basis weight of tobacco leaves) .

[0023] Then the burley tobacco is used as a raw material to prepare cigarettes.

Embodiment 2

[0025] This embodiment relates to the application of sodium phosphate buffer in reducing the amount of TSNAs released in cigarette smoke, which specifically includes the following steps:

[0026] Take 1kg of threshed and rebaked Burley tobacco, prepare a sodium phosphate buffer solution containing 20.25% disodium hydrogen phosphate and 0.9% sodium dihydrogen phosphate, and spray 200mL of sodium phosphate buffer evenly on the tobacco in the form of mist On the surface, make the sheet tobacco fully absorb the sodium phosphate buffer solution, so that the content of disodium hydrogen phosphate in the sheet tobacco is 4.5% (relative to the dry basis weight of tobacco leaves), and the content of sodium dihydrogen phosphate is 0.20% (relative to the dry basis weight of tobacco leaves) .

[0027] Then the burley tobacco is used as a raw material to prepare cigarettes.

Embodiment 3

[0029] This embodiment relates to a cigarette product. Sodium dihydrogen phosphate and disodium hydrogen phosphate are added to raw materials for preparing the cigarette product. The mass of the disodium hydrogen phosphate is 3.0% of the dry weight of the shredded tobacco, and the mass of the sodium dihydrogen phosphate is 0.13% of the dry weight of the shredded tobacco.

Abstract

The invention relates to the application of sodium phosphate buffer solution in reducing the release amount of TSNAs from cigarette smoke. The invention finds that the release amount of TSNAs in cigarette smoke is significantly lower than that of cigarette samples without application of sodium phosphate when phosphate buffer is added to cigarettes in the form of an endogenous additive.

Description

technical field [0001] The invention belongs to the field of reducing the release of harmful components in cigarette smoke, and in particular relates to the application of sodium phosphate buffer solution in reducing the release of TSNAs in cigarette smoke. Background technique [0002] TSNAs (TSNAs, Tobacco Specific N-Nitrosamines) are a class of carcinogenic components unique to tobacco. They are metabolized slowly in the human body, have a long half-life, and are extremely harmful to human health. Therefore, TSNAs have been included in multiple lists of tobacco harmful ingredients, and are one of the harmful ingredients in cigarettes that need to be disclosed and reduced. At present, people are mainly concerned about the following four kinds: 4-(N-methyl-nitrosamine)-1-(3-pyridyl)-1-butanone (NNK, 4-(N-methyl-N-nitrosamino)-1 -(3-pyridyl)-1-butanone), N-nitroso demethyl nicotine (NNN, N'-Nitrosonornicotine), N-nitroso neonicotine (NAT, N'-Nitrosoanatabine), N- Nitroso n...
