Problems solved by technology

In addition, cigar processing mainly relies on handwork, and it is impossible to reduce TSNAs in finished cigars through industrial means, so the TSNAs content of tobacco leaves has a great impact on the TSNAs content of cigar products

Embodiment 1

[0022] The application of melatonin in reducing the content of tobacco-specific nitrosamines in the cigar fermentation process, the steps are:

[0023] (1) Spray Na at a ratio of 1:9 on the cigar leaves to be fermented 2 CO 3 -NaHCO 3 The buffer adjusts the pH to 5.5;

[0024] (2) Prepare the spray liquid of melatonin, the concentration of melatonin is 15 μmol / ml;

[0025] (3) Spray the melatonin spray solution prepared in step (2) evenly on the cigar leaves treated in step (1), and the amount of the spray solution is 1 / 4 of the leaf weight. .

Embodiment 2

[0027] The application of melatonin in reducing the content of tobacco-specific nitrosamines in the cigar fermentation process, the steps are:

[0028] (1) Spray Na at a ratio of 9:1 on the cigar leaves to be fermented 2 CO 3 -NaHCO 3 The buffer adjusts the pH to 6.34;

[0029] (2) Prepare the spray solution of melatonin, the concentration of melatonin is 30 μmol / ml;

[0030] (3) Spray the melatonin spray solution prepared in step (2) evenly on the cigar leaves treated in step (1), and the amount of the spray solution is 1 / 4 of the leaf weight. .

Embodiment 3

[0032] The application of melatonin in reducing the content of tobacco-specific nitrosamines in the cigar fermentation process, the steps are:

[0033] (1) Spray Na at a ratio of 1:1 on the cigar leaves to be fermented 2 CO 3 -NaHCO 3 The buffer adjusts the pH to 5.74;

[0034] (2) Prepare the spray solution of melatonin, the concentration of melatonin is 0 μmol / ml;

[0035] (3) Spray the melatonin spray solution prepared in step (2) evenly on the cigar leaves treated in step (1), and the amount of the spray solution is 1 / 4 of the leaf weight. .

Abstract

The invention belongs to the field of cigar preparation and relates to how to reduce the content of nitrosamines in cigars, in particular to the application of melatonin in reducing the content of tobacco-specific nitrosamines in the fermentation process of cigars. The steps are: Na sprayed on the cigar leaves to be fermented 2 CO 3 ‑NaHCO 3 The buffer solution adjusts the pH; the melatonin spray solution with different concentrations is prepared; and the prepared melatonin spray solution is evenly sprayed on the cigar leaves. The content of nitrosamines in the treated fermented cigar leaves decreased by 14.61‑17.83%, and the finished cigars rolled with the treated fermented cigar leaves showed a decrease of 12.92‑12.92‑ 16.04%.

Description

technical field [0001] The invention belongs to the field of cigar preparation and relates to how to reduce the content of nitrosamines in cigars, in particular to the application of melatonin in reducing the content of tobacco-specific nitrosamines in the fermentation process of cigars. Background technique [0002] Tobacco Specific Nitrosamines (TSNAs) are important harmful components present in tobacco and tobacco products, and have always been a hot spot in international tobacco research. There are four common TSNAs, namely N -nitrosonornicotine (NNN), 4-( N -methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), N -Nitrosodenicotine (NAT) and N -Nitrosobasine (NAB), of which NNN and NNK have been proven to be carcinogenic in animals. my country's tobacco industry attaches great importance to tobacco harm reduction research, and has listed TSNAs as one of the "seven harmful components" of tobacco for major special research and has achieved remarkable results. The conten...
