Embodiment 1

[0019] The 2011 Kunming K326BSF tobacco leaves were processed by "YC / T146-2010 Tobacco Leaf Threshing and Rebaking Process Specification" (referred to as the standard process technology) and the technical method of the present invention, and 200g of samples were taken at the packaging place every 30min, 10 times in total, and mixed evenly. In order to prepare for the determination of NNK release in the smoke of tobacco leaf samples.

[0020] The cigarette samples are conditioned under the conditions specified in GB / T16447-2004 "Atmospheric Environment for Conditioning and Testing of Tobacco and Tobacco Products", and the cigarettes are smoked under the conditions specified in GB / T16450-2004 "Definition and Standard Conditions of Smoking Machines for Routine Analysis".

Abstract

The invention discloses a leaf tobacco processing method capable of selectively reducing a release amount of NNK (Nitrosamine) in cigarette smoke. The leaf tobacco processing method comprises the steps of: firstly, preheating wet leaf barrel, and charging when circulatory hot wind is at 80 DEG C to 120 DEG C; then adjusting a hot steam valve and a wet steam valve based on the positions of the processed leaf tobacco, and respectively controlling a temperature and a moisture content of the wet leaf tobacco; and finally, processing by adopting full steam at a temperature which is accordance with the technical requirements of YC / T146-2010 Leaf Tobacco Threshing and Redrying Process Specification. The method has obvious effects of selectively reducing the release amount of the NNK in the cigarette smoke, achieves the reduction amplitude of 11.20-38.21%, has good repeatability, is applicable to the practical threshing and redrying production, expands the leaf tobacco processing technology of reducing harmful components in the cigarette smoke, and has relatively good practical significance and reference function for harm reduction and tar reduction in the industry.

Description

technical field [0001] The invention belongs to the technical field of leaf threshing and redrying, and in particular relates to a tobacco leaf processing method capable of selectively reducing the NNK release amount of cigarette smoke. Background technique [0002] 4-(N-methylnitrosamine)-1-(3-pyridyl)-1-butanone (NNK) is a component with a high content in tobacco-specific nitrosamines TSNAs, and is the component of nicotine prepared in tobacco leaves. , Processing and cigarette burning process formed by nitrosation. [0003] NNK is a potent and selective inducer of lung adenocarcinoma in rodents. Injecting only 1 μg of NNK into voles once can cause a high incidence of lung cancer. Its main metabolite N'-4-(formazol N-nitrosamine 1-(3-pyridyl-1-butanol (NNAL) is the only substance known to cause pancreatic cancer in tobacco smoke, so in 2008 the State Tobacco Monopoly "Notice on Coke Reduction Work" (Guoyanke [2008] No. 471) clearly pointed out that NNK is one of the impo...
