Description

Tobacco shred with surface sprayed with selenium-containing organic acid and product containing tobacco shred

Technical Field

The invention relates to a tobacco shred with selenium-containing organic acid sprayed on the surface and a product containing the tobacco shred, belonging to the field of new materials.

Background

The food and agriculture organization of the united nations classifies the tobacco into: the main materials of the tobacco cigarettes are cut tobacco, and the cut tobacco in the tobacco cigarettes is mainly smoked by smokers in a burning mode of about 700 ℃ or a non-burning mode of heating at about 300 ℃. About 10 hundred million smokers worldwide have 13 times of lung cancer risk of smokers than non-smokers, about 85 percent of lung cancer death people are caused by smoking, nicotine addiction is the main reason for smokers to insist on smoking, and researches show that: the nicotine and the metabolite thereof promote the growth and the metastasis of tumor and cancer cells by promoting cell proliferation, infiltration, epithelial intercellular substance-like transformation and angiogenesis; in addition, due to soil pollution and the fact that metal mechanical equipment is often used in the process of processing tobacco leaves into cut tobacco in harvesting, sorting, baking and the like, heavy metal elements harmful to human bodies, such as cadmium (Cd), antimony (Sb), lead (Pb), chromium (Cr), mercury (Hg) and the like, are often mixed in the smoke.

Research shows that people can prevent lung cancer, tumor, liver cancer and other diseases, improve the immunity of the organism, maintain the normal functions of heart, liver, lung, stomach and other important organs, prevent the occurrence of senile cardiovascular and cerebrovascular diseases, and prevent the harm of various toxic heavy metals and harmful compounds to the liver. Therefore, the harm of nicotine and heavy metals in the tobacco smoke to human bodies can be reduced by using the tobacco rich in selenium. For example, patent documents for increasing the content of selenium in plant tobacco leaves by planting methods such as soil improvement and fertilizer spraying include CN201710048678.0, CN201810018411.1, CN201310127171.6, CN200810025643.6, CN201810234487.8, CN200810025643.6, CN201710731890.7, CN201110352994.x, cn201810136969.x, CN201810669702.7, cn201610858338.x, CN201911050041.0, CN201710247583.1, 201410112366.8, CN201910087368.9, CN201410056251.1 and CN 201710149030.2. Patent application No. CN200310125140.3 discloses a method for adding inorganic elemental selenium to tobacco produced by conventional processes, however, elemental selenium belongs to inorganic selenium, which is highly toxic, prone to cumulative poisoning accidents, and not suitable for direct use by humans and animals, such as inorganic selenium prohibited in japanese prescribed feeds, and common inorganic selenium such as: simple substance selenium, selenium-containing mineral substances, sodium selenite, sodium selenate, yeast selenium with a large amount of inorganic selenium residues, malt selenium and the like, and similarly, published patents of adding inorganic selenium in tobacco processing include CN201810016151.4, CN201810008723.4 and the like, and although the published technologies can also reduce the harm of nicotine and heavy metals in the electronic cigarette to human bodies, the inorganic selenium is used to cause new harm to human bodies.

In addition, due to the alkaline pungent smell of free nicotine molecules in the hot smoke of the tobacco, the throat of a user is dry and itchy and the severe cough is caused, and the smooth and good taste experience of the smokers on the cigarette is reduced.

Disclosure of Invention

Problems to be solved by the invention

Selenium element can reduce the harm of nicotine and heavy metal in tobacco to human body, however, the current method of improving the content of selenium element in plant tobacco leaves by planting methods such as soil improvement or fertilizer spraying has poor effect due to the influence of the difference of absorption capacity of tobacco leaves, geographical environment, growth cycle, planting process and the like. In addition, the mode of adding inorganic selenium during tobacco processing has poor feasibility because the inorganic selenium has high toxicity and is easy to cause accumulated poisoning accidents and bring new harm to human bodies.

The product containing the tobacco shred with the selenium-containing organic acid sprayed and doped on the surface comprises a cigarette smoking product containing the tobacco shred and a heating non-burning smoking set containing the tobacco shred.

The technical principle of the scheme is as follows: in the process that cigarette tobacco shreds are smoked by smokers in a burning mode at about 700 ℃ or a heating non-burning mode at about 300 ℃, alkaline nicotine contained in the tobacco shreds and selenium-containing organic acid doped on the surfaces of the tobacco shreds are sprayed in advance, acid-base neutralization chemical reaction can be carried out in the burnt tobacco bodies and overflowed smoke, organic selenium-containing nicotine salt without peculiar smell is generated, the alkaline pungent smell of free nicotine molecules in the smoke is reduced, the smooth and good taste experience of the smokers on cigarettes is improved, the selenium element of the human body is introduced by the selenium-containing organic acid, and the harm of nicotine and heavy metal in the smoke to the human body can be reduced. The chemical reaction of the selenium-containing organic acid and the alkaline nicotine to generate the organic selenium-containing nicotine salt is as follows:

wherein, A and B represent other chemical substances except selenium and terminal carboxylic acid group in the structural formula of the selenium-containing organic acid, such as hydroxyl, amino and the like, and n represents natural numbers of 1, 2, 3 and the like.
