Problems solved by technology

The currently reported technologies for reducing the NNN of cigarette products are: (1) Adding additives with strong adsorption to cigarette filters, but this often results in loss of cigarette aroma and smoke; (2) Application of microwave in silk making ; (3) Choose tobacco leaves with low TSNAs content
However, there is no report on the research results directly aimed at reducing NNN by tobacco leaf treatment

Embodiment 1

[0010] Cut the Burley tobacco leaf sample into shredded tobacco, remove impurities, sift out crushed tobacco and tobacco powder, mix evenly, and equilibrate at a temperature of 22±1°C and a humidity of 60±2% for 48 hours, and divide it into four parts. One was used as a control, and the other three were sealed with sample bags, and placed in a freezer at 0°C for 1 hour, 2 hours, and 3 hours, and then the control and each treated sample were taken out for alcoholization under the same conditions, and the samples of each treated tobacco leaf were monitored for 6 to 12 hours. The change of NNN content during the month aging process. It can be seen from Table 1 that compared with the control, the NNN content of the tobacco samples treated at 0°C for 1h, 2h and 3h all showed a decreasing trend during the aging process from 6 to 12 months, and the longer the treatment time, the greater the reduction rate. The largest is 3h (16.48%), followed by 2h (16.48%), and the smallest is 1h. ...

Embodiment 2

[0014] Cut the Burley tobacco leaf sample into shredded tobacco, remove impurities, sift out crushed tobacco and tobacco powder, mix evenly, and equilibrate at a temperature of 22±1°C and a humidity of 60±2% for 48 hours, and divide it into four parts. One was used as a control, and the other three were sealed with sample bags, and placed in a freezer at -20°C for 1h, 2h and 3h, then the control and each treated sample were taken out for alcoholization under the same conditions, and the tobacco leaf samples of each treatment were monitored for 6-6 hours. Changes in NNN content during 12-month aging. It can be seen from Table 2 that compared with the control, the NNN content of tobacco leaves treated at -20°C for 1h, 2h and 3h showed a decreasing trend from June to December, and the largest decrease was at 2h (about 10%), followed by 3h, the minimum is 1h; -20℃ treatment can reduce the NNN content by 16.37%. This indicated that the treatment of shredded tobacco at -20°C for 1h...

Embodiment 3

[0018] Cut Burley tobacco leaf samples into shredded tobacco, remove impurities, sift out crushed tobacco and tobacco dust, mix them evenly, and equilibrate them for 48 hours at a temperature of 22±1°C and a humidity of 60±2%, and divide them into four parts. One was used as a control, and the other three were sealed with sample bags, and placed in a freezer at -40°C for 1h, 2h and 3h, then the control and each treated sample were taken out for alcoholization under the same conditions, and the tobacco leaf samples of each treatment were monitored for 6-6 hours. Changes in NNN content during 12-month aging. It can be seen from Table 3 that compared with the control, under the condition of -40°C, only the NNN content of the 1h and 2h tobacco leaves showed a decreasing trend in September and December, and the rest of the treatments were higher than the control. This shows that the effect of reducing the NNN of shredded tobacco at -40℃ for 1h to 3h is not obvious.

Abstract

The invention discloses a method reducing (N'-Nitrosonornicotine) NNN content in tobaccos. Firstly, the tobaccos are chopped into tobacco shreds, and then the tobacco shreds are balanced for 48 hours at the temperature of 22+_1 DEG C and at the humidity of 60+_2%, sealed through plastic bags, placed under the condition of 0-20 DEG C for 1-3 hours and stored naturally. The technical process is simple to operate and strong in controllability. The method is obvious in reducing NNN content effect and does not need to add any additive, thereby being safe and reliable. In addition, researchers study damage-reducing technology from tobacco pretreatment, and therefore the method reducing the NNN content in the tobaccos is strong in novelty and has important theoretical and practical significance to explore and research damage reduction new ways.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing, and in particular relates to a method capable of effectively reducing the NNN content in tobacco leaves. Background technique [0002] Tobacco-specific nitrosamines (TSNAs) are carcinogens of great concern to people. In recent years, as smoking and health have attracted increasing attention, how to reduce the content of tobacco-specific nitrosamines has become a hot spot and focus of research. Among them: N-nitrosonornicotine (NNN) is one of the components with higher content and the strongest carcinogenicity in TSNAs, mainly present in unburned tobacco. It spreads rapidly in the human body and can induce the occurrence of tumors such as lung cancer, oral cancer, esophageal cancer, and liver cancer. It is now generally accepted that NNN plays a major role in tobacco-not-burned-induced oral cancer. The currently reported technologies for reducing the NNN of cigarette products are: (...
