Description

Shredded tobacco, its preparation method and cigarette

technical field

The present application relates to the technical field of tobacco products, in particular to shredded tobacco, its preparation method and cigarettes.

Background technique

Heat-not-burn cigarettes are one of the important components of new tobacco products. Compared with combustible cigarettes, which are smoked by lighting shredded tobacco, heat-not-burn cigarettes use a heat source to heat the atomized substrate to release smoke (below 500 ° C), fog The chemical substrate is only heated and does not burn.

In recent years, new tobacco products have shown a rapid development trend. Compared with traditional tobacco, new tobacco products have a huge advantage of similar taste but extremely low harm. Although they currently account for a small proportion of global tobacco sales, they are growing rapidly.

In terms of market scope, the heated cigarette product market is constantly expanding, and the market structure is also constantly evolving. From the perspective of cigarette sales, burning cigarettes is still the mainstream in the market. The raw materials of heat-not-burn cigarettes on sale or under research are mainly reconstituted tobacco leaves, which are widely used because of their strong plasticity, high ability to load atomizers, and ability to maintain the active ingredients of tobacco leaves. However, special heating appliances are required for smoking. Moreover, the heating appliances and heating methods of various tobacco companies are different, and at the same time, limited by each other's patent barriers, the commonality between heating appliances cannot be guaranteed, which has caused certain limitations for consumers.

At present, the raw materials of heat-not-burn cigarettes mainly include reconstituted tobacco leaves, granules and flue-cured tobacco shreds. Reconstituted tobacco has been widely used because of its strong plasticity, high ability to load aerosols and the ability to maintain the active components of tobacco. However, the reagents such as atomizers, adhesives, flavors and fragrances added in the production process of reconstituted tobacco leaves will also be heated during the heating and smoking process, which has a potential impact on sensory quality and smoking experience. Granular raw materials are tobacco raw materials that are pulverized and processed into sheet or granular cigarette raw materials, but have the disadvantages of large fluctuations in draw resistance and unstable smoke. Flue-cured tobacco shredded tobacco is a relatively mature craft product, which has the advantages of luster and oil, plump and delicate aroma, harmony, no miscellaneous gas, no irritation, high purity and comfort, but the loading capacity of the atomizer is low.
