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:
