Technical Field

The invention belongs to the technical field of cigarette preparation, and particularly relates to a method for preparing a cigarette sheet which is not burnt by heating and is prepared from bacterial cellulose obtained by fermenting tobacco extract.

Background

The cigarette which is not burnt by heating is a novel tobacco product and is characterized in that: firstly, low-temperature heating (below 500 ℃) is not combusted; secondly, nicotine is provided, so that the physiological needs of consumers can be met; and compared with the traditional cigarette, the reduction of most harmful components in the cigarette smoke is more than 90%, so that the harm to consumers and surrounding people is greatly reduced.

The preparation method of the prior art heating non-combustion cigarette sheet mainly comprises a dry method, a paper-making method, a thick pulp method and a rolling method. The tobacco leaves reproduced by the thick pulp method in the four methods have good aroma, and the tensile strength is inferior to that of the tobacco leaves reproduced by the paper-making method; the thickness control difficulty is higher during the formation of the dry reconstituted tobacco sheet base, and the load uniformity, thickness and quantitative stability of the dry sheet coating liquid are further influenced; the reconstituted tobacco by the rolling method has low elongation and low tensile strength, and is easy to break and fracture during shredding or gathering forming; the tensile strength and aftertaste of the paper-making method are superior to those of the cigarette sheets which are prepared by the rolling method and the thick pulp method and are not burnt when being heated, but because the paper-making method is influenced by the coating rate, the content of effective load dry matters is lower than that of the tobacco leaves reproduced by the thick pulp method and the rolling method, the smoke yield and the fragrance amount are slightly lower. Therefore, it is a challenge in the art to provide a heated non-burning sheet that has high strength and toughness, has a high loading capacity for the smoker, and has sufficient tobacco flavor.

Disclosure of Invention
