Description
Technical Field
The application relates to the technical field of tobacco formulas, in particular to a tobacco shred containing a hyaluronic acid composition and a preparation method thereof.
Background
The tobacco shred is prepared by cutting tobacco leaf into thread, granule, sheet, powder or other shapes, adding adjuvants, fermenting, storing, and making into tobacco product for sale and smoking without rolling. Such as pipe tobacco, motley tobacco, tobacco powder, hookah, yellow-red cut tobacco, etc. The taste of the smoke is also very different depending on the place of origin. There are various methods for using tobacco shreds, and the tobacco shreds may be rolled directly into any shape with cigarette paper and then smoked, or rolled into cigarette shape with a special cigarette making machine, or further used with a smoking set such as a pipe. The cigarette is the most widely used method of the tobacco shred at present, and the tobacco shred of the genuine cigarette mainly comprises the components of cut leaves, cut stems, tobacco sheet shreds and the like.
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 humans and vertebrate animals 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, non-sensitization, good biocompatibility and the like. HA molecular chains are mutually wound into a continuous network 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 the HA molecular chains are known as the best natural moisturizing factors in the world.
Hyaluronic Acid (HA) is an important component of the extracellular matrix (ECM). The lung is rich in HA, which is synthesized by mesenchymal cells, particularly fibroblasts, and then enters the blood via the lymphatic circulation. Modern medical studies have shown that HA HAs a number of important functions in the pulmonary ECM: it HAs been increasingly appreciated by respiratory researchers because it HAs the effects of hydrating, maintaining the stability of the internal environment, maintaining the structure and function of cells, regulating inflammatory responses, affecting tissue repair and reconstruction, and protecting lung tissue from damage in various respiratory diseases. (Wang Ximing, Chen Zhi Kui-hyaluronic acid and respiratory diseases).
At present, most of tobacco shreds prepared at home and abroad are prepared into finished tobacco shreds for cigarettes by mixing the tobacco shreds with spices in a baking mode. The finished tobacco shreds used in cigarettes have different tastes according to different production places, but most of the cigarettes have the defects of thick smoke, strong irritation, dry and uncomfortable feeling and the like, and harmful substances such as tar and the like released from the tobacco shreds have certain harm to human bodies.

And (3) knotting: as can be seen from the comparison of the detection results with the existing cigarette samples on the market, the tobacco shreds prepared by the method have high water content, zinc hyaluronate and sodium hyaluronate. The sodium hyaluronate with the molecular weight less than or equal to 5kDa in the cut tobacco prepared by the application can inhibit the generation of cell inflammatory factors and prevent excessive inflammatory reaction in the wound healing process. The zinc hyaluronate has the functions of diminishing inflammation and inhibiting bacteria, so that the addition of a preservative in cigarettes is reduced, and the cost is reduced.
While embodiments of the present application have been described above, the present application is not limited to the specific embodiments and applications described above, which are intended to be illustrative, instructive, and not limiting. Those skilled in the art, having the benefit of this disclosure, may effect numerous modifications thereto and changes may be made without departing from the scope of the invention as defined by the appended claims.
