Cigarette processing method for lowering benzo[a] pyrene content in smoke

Abstract

The invention relates to a treatment method for reducing the content of benzo[a]pyrene in cigarette smoke, which is characterized in that finished cigarettes or boxed cigarettes are placed in a gamma-ray radiation area for gamma-ray irradiation, and the adopted gamma-ray radiation source It is the isotope cobalt-60 or cesium-137 or iridium-192 or selenium-75, and the radiation dose is 4KGy-40KGy, which can reduce the content of benzo[a]pyrene in cigarette smoke by 12-70%. The smoking quality of the cigarettes is basically not affected; in addition, the gamma ray irradiation can also effectively prevent the mildew of the finished cigarettes during storage.

Description

technical field [0001] The invention relates to a technology for reducing harmful components in cigarette smoke, in particular to a treatment technology capable of effectively reducing the content of benzo[a]pyrene in finished cigarette smoke. Background technique [0002] With the continuous improvement of people's living standards and the advancement of science and technology, the impact of smoking on health has attracted much social attention. At present, tobacco technology has initially revealed that the harmful components in cigarette tar are one of the main substances that endanger the health of smokers. Tar contains a variety of carcinogens and carcinogens, such as the well-known carcinogen benzo[a]pyrene, One of the reasons for its carcinogenicity is that benzo[a]pyrene is first hydroxylated at the 6-position to form 6-hydroxybenzo[a]pyrene (which can form a covalent compound with nucleic acid), which is further oxidized to 6-oxybenzene And [a] pyrene free radicals,...

Problems solved by technology

[0003] In recent years, the domestic and foreign tobacco industries, from the perspective of cigarette processing technology, have reduced the cigarette smoking rate by improving the air permeability of cigarette paper, adopting filters with different structures, punching and diluting, expanding shredded tobacco stems and tobacco sheets, and adding Chinese herbal medicine ingredients. The amount of tar has achieved some gratifying results, but the tar content of cigarettes currently on the market is still generally high
