Description

Cigarette paper containing hyaluronic acid and preparation method thereof

Technical Field

The invention belongs to the technical field of biology, and particularly relates to cigarette paper containing hyaluronic acid and a preparation method thereof.

Background

The cigarette paper is used as a cigarette auxiliary material and occupies an extremely important position in cigarette manufacturing. The main raw material of most cigarette paper is bleached hemp pulp, and part of bleached wood pulp or straw pulp is also mixed, so that the cigarette paper is a special thin-sheet paper for wrapping tobacco to make cigarettes. Hyaluronic Acid (HA) is a linear polymeric polysaccharide formed by repeating glycosidic linkages of disaccharide units consisting of glucuronic acid and N-acetylglucosamine. HA is widely found in the human and vertebrate bodies and is one of several glycosaminoglycans that make up the extracellular matrix. The polysaccharide has the most content in human dermis and joint synovial fluid, and has the properties of high-molecular polysaccharide such as water retention, lubrication, no sensitization, good biocompatibility and the like. HA molecular chains are mutually wound into a continuous net structure, and water molecules act with the HA molecular chains through polar bonds, so that the HA molecules can absorb and keep thousands of times of water by weight per se, and are generally recognized as the best natural moisturizing factor in the world.

At present, cigarette paper prepared at home and abroad has single effect and is only used for wrapping tobacco shreds, additives such as coloring and flavoring are added into part of the cigarette paper for more attractive appearance, but the cigarette paper does not have much benefit on the health of human bodies, and harmful substances such as tar and the like released from the tobacco shreds damage the human bodies to a certain extent.

Test examples

Determination of substance content in combustion flue gas

The detection method comprises the following steps: the cigarette paper in examples 1-8 and comparative examples 1-3 of the invention is wrapped with the same tobacco shred to prepare a single cigarette, 5 cigarettes and cigarettes of common brands in the market are respectively combusted, the smoke of the single cigarette is respectively collected to detect the content of harmful substances, and then the average value is taken, and the detection items are cigarette tar, nicotine, phenols, vitamins and tea polyphenol in the smoke.

Specifically, the method for collecting and detecting the components comprises the following steps:

smoke tar oil: weighing about 150g of clean degreased cotton, accurately weighing on a balance, recording the result, putting the weighed cotton at one end of an adsorption tube, sucking the other end of the adsorption tube by an ear washing ball, wherein the sucking frequency is 4 times/minute, taking out the cotton after the cigarette is sucked and burned out, accurately weighing on the balance, recording the result, and repeating 3 times for each cigarette to take the average value.

Nicotine: a sample solution is obtained by a distillation extraction method, and then quantitative measurement is carried out by gas chromatography.

Tea polyphenol: collecting a sample solution of the smoke dissolved in water, and determining by using a determination method in GB/T1259-.

Vitamins: the method mainly comprises the steps of oxidizing vitamins by an oxidizing agent by a fluorescence spectrophotometry, reacting with a reaction reagent to form a nitrogen-containing cyclic condensation product, measuring the content of the nitrogen-containing cyclic condensation product by a spectrophotometer, and finally converting the content of the nitrogen-containing cyclic condensation product into the content of vitamins.

Dust coating Performance test

The cigarette paper in the examples 1-8 and the comparative examples 1-3 is wrapped with the same tobacco shred to prepare a single cigarette, 5 cigarettes and the common brand cigarettes in the market are combusted, and the length of the cigarette ash in the combustion process is seen in a natural state. The longer the length of ash on the cigarette during combustion, the better the ash loading.

The detection average data are shown in table 2. Wherein the precipitation rate of the vitamins is the ratio of the content of the vitamins collected after the cigarettes are burnt to the content of the vitamins contained in the cigarettes. The precipitation rate of tea polyphenol is the ratio of the content of tea polyphenol collected after the cigarette is burnt to the content of tea polyphenol contained in the cigarette.

TABLE 2 Smoke content of cigarettes produced using the cigarette papers of the respective examples and comparative examples

Compared with the existing cigarette samples in the market, the detection result shows that the content of harmful substances (tobacco tar, nicotine and phenols) separated out during combustion of the cigarette made of the cigarette paper containing hyaluronic acid is far less than that of the existing cigarette, so that the harm to human bodies is greatly reduced; meanwhile, the ash wrapping performance of the cigarette is improved. The content of the vitamin and the tea polyphenol loaded by the hyaluronic acid after combustion is far more than that of the cigarette without the hyaluronic acid, so that the effect of the vitamin and the tea polyphenol is greatly improved. However, the amount of hyaluronic acid added is not as large as possible, and the effect is best in the preferred range of the invention, and excessive hyaluronic acid only causes waste. Specifically, when the dosage of hyaluronic acid is increased from 0.05g to 3g, the precipitation rate of vitamins and tea polyphenols is not increased.

The precipitation rate of the vitamin and the tea polyphenol loaded by the hyaluronic acid after combustion is far higher than that of the cigarette without the hyaluronic acid, which is improved by nearly 1 time, and the effectiveness of the vitamin and the tea polyphenol is greatly improved. The vitamins are directly added into the cigarette base paper to fully contact with burning tobacco shreds, so that the capability of removing free radicals in the tobacco shreds is greatly improved, the tea polyphenols reduce the activity of the free radicals in a human body after entering the human body along with volatilized smoke, and one of the vitamins is inside and outside to help coordinate the generation and the removal of the free radicals in the human body and the balance of oxidation and reduction. The ash coating performance is improved, and the fly of the ash in the environment can be prevented. The spread of fire sources can be reduced, and the fire disaster can be avoided.
