Description

A Novel Tobacco Moisturizer and Its Application

technical field

The invention relates to a novel tobacco humectant and its application, belonging to the technical field of tobacco processing.

Background technique

With the continuous improvement of people's living standards in our country, consumers are paying more and more attention to the smoking quality and safety of cigarettes. Improving the safety of smoking has gradually become a common goal for the survival and development of my country's tobacco industry. With the sharp reduction of tar in tobacco products in my country, the original aroma quality of tobacco leaves has been greatly affected. The technology of tar reduction and flavor preservation has become the key to restricting the development of cigarettes, especially now that the tar content has dropped significantly. Under the circumstances, it will be more and more difficult to further reduce the coke significantly while maintaining the smoking taste of cigarettes. How to reduce the amount of tar in cigarettes while still being able to accept the flavor of cigarettes has become the main subject of the cigarette industry, and it is also a key factor affecting the reduction of tar in cigarette products in my country. After ten years of research and development, my country's tobacco industry has generally mastered the technology of reducing cigarette tar. Through technical measures such as reforming the formula structure of tobacco leaves, using cigarette paper with high air permeability and fast static burning speed, and applying filter ventilation and dilution, it can effectively Destination reduces tar. However, the current common problems in my country's tobacco companies are: the sensory dryness brought about by the use of reconstituted tobacco leaves, filter ventilation and dilution in order to reduce tar; Dry, the moisture in the shredded tobacco of the cigarette is easy to lose, so that the cigarette cannot guarantee a better smoking effect.

The domestic tobacco industry has developed rapidly in recent years, and its scientific research strength and innovation level have been greatly improved. However, there is still a gap with well-known foreign companies in the field of cigarette flavoring and moisturizing applications. The humectants commonly used by my country's tobacco companies are polyhydric alcohols, such as propylene glycol, glycerin, sorbitol, etc., and the moisturizing effect is not ideal. With the continuous development of my country's tobacco industry and the expansion of the product market, Under different climatic conditions, ensuring that cigarettes have a better smoking effect and compensating for the loss of aroma caused by coke reduction is an urgent problem for enterprises to solve.

The research found that the main components in propolis are: a flavonoids: mainly including flavonoids, flavonols and dihydroflavonoids; b terpenes: mainly monoterpenes and sesquiterpenes in propolis, A few are diterpenoids; c-acid compounds: mainly include benzoic acid, p-hydroxybenzoic acid, cinnamic acid and their derivatives; d-alcohol compounds: mainly include benzoic acid, Z-betulinol, acetoxy-2 - Betulinol, etc.; e phenol, aldehyde, ketone, ester, ether compounds: mainly eugenol, vanilla aldehyde, isovanillin aldehyde, benzaldehyde, β-ring citral, 4,5-dimethyl- 4 Benzene, cyclohexenone, p-coumarate, caffeate, cyclohexanol benzoate, p-coumaryl vanillate, styrene ether, p-methoxystyrene ether, etc.; f enzymes Substances: such as amylase, cathepsin, lipase, trypsin and other active enzymes; g vitamins: such as vitamin B1, vitamin P, provitamin A, etc.; h constant and trace elements: aluminum, iron, calcium, silicon, More than 30 kinds of strontium, zinc, cobalt, nickel, chromium, vanadium, tin, barium, titanium, selenium, molybdenum, antimony, etc.; other substances: various amino acids, polysaccharides, etc. It can be seen that the ingredients in propolis are very rich, some of these ingredients have the effect of moisturizing, and some ingredients also have rare natural antioxidant properties, which can effectively remove free radicals in smoke and enhance the smoking safety of cigarettes. Moreover, propolis itself has a pleasing aroma. These characteristics make propolis have a good application prospect in cigarettes and are worthy of further research.

Contents of the invention

The purpose of the present invention is to develop a new tobacco humectant-natural propolis extract, or a mixed solution of natural propolis extract and propylene glycol, glycerol or sorbitol. Use solvent extraction, supercritical extraction or ultrasonic extraction to obtain propolis extract from natural propolis, add the extract into propylene glycol, glycerol or sorbitol according to the ratio of 10-100%, spray it evenly on the shredded tobacco, spray The addition ratio is 0.1-1.0%, and the moisture content in shredded tobacco is determined according to the method stipulated in YC/T28.8-1996 "Determination of Moisture in Physical Properties of Cigarettes". Or a traditional moisturizer like sorbitol.

The present invention is realized through the following technical solutions:

A novel tobacco humectant is natural propolis extract or a mixed solution of natural propolis extract and water, propylene glycol, glycerol or sorbitol.

The mass ratio of natural propolis extract to propylene glycol, glycerol or sorbitol is 10-90%:90-10%.

The propolis extract of the present invention is preferably extracted from natural propolis by solvent extraction, supercritical extraction or ultrasonic extraction.

In the method for using the above-mentioned novel tobacco humectant, the humectant is evenly sprayed onto shredded tobacco, and the addition ratio is 0.1-1.5% by weight of shredded tobacco.

The moisture content in shredded tobacco is measured according to the method stipulated in YC/T28.8-1996 "Determination of Moisture in Cigarette Physical Properties", and the results show that the moisture retention effect exceeds that of traditional humectants such as propylene glycol, glycerin or sorbitol commonly used at present. .

In addition, the new tobacco humectant can effectively remove free radicals in smoke and enhance the smoking safety of cigarettes.
