Problems solved by technology

However, the reason why heat-not-burn tobacco products have not been widely accepted is mainly because the smoke release performance and smoke sensory quality of the currently used cigarette core materials in the heat-not-burn state are not ideal.

Embodiment 1

[0014] Take 1 part of flue-cured tobacco shreds and add them to the extraction container, then add 15 parts of 40% ethanol aqueous solution, soak at 30 °C for 48 h, and filter under reduced pressure to obtain tobacco extract. The extract solution is evaporated to remove ethanol under reduced pressure, and then freeze-dried to obtain flue-cured tobacco type solid tobacco extract.

Embodiment 2

[0016] Take 3 parts of flue-cured tobacco shreds, 1 part of Burley tobacco shreds and 1 part of oriental tobacco shreds and mix them into the extraction container, then add 50 parts of 60% ethanol aqueous solution, soak at 40 °C for 24 h, filter under reduced pressure to obtain tobacco extract liquid. After the extract solution is evaporated to remove ethanol under reduced pressure, it is spray-dried to obtain a mixed solid tobacco extract.

Embodiment 3

[0018] 100 parts of starch polysaccharide, 30 parts of flue-cured solid tobacco extract, 15 parts of glycerol, 15 parts of Mg(OH) 2 Add deionized water, fully disperse and dissolve, gelatinize at 80 °C for 1 h, and then degas under reduced pressure for 20 min to obtain a film-forming liquid. The film-forming solution was spread on a glass template by casting method to form a film, which was dried at 35 °C for 48 h and then released. After the prepared film was equilibrated for 48 h in an environment with a temperature of 22 ℃ and a relative humidity of 60%, a tobacco film suitable for heat-not-burn tobacco products was obtained. The tobacco film has good smoke release performance in a heating-not-burning state, and the released smoke presents obvious characteristics of flue-cured tobacco style, and has good satisfaction and comfort.

Abstract

A tobacco film preparing method for heated non-combustion tobacco products is characterized by sequentially comprising the following steps of (1) preparing a tobacco extract: performing digestion on tobacco raw materials with an ethanol solution, obtaining a tobacco extracting solution by separating and obtaining a solid tobacco extract by decompressing, evaporating and drying; (2) preparing a tobacco film: proportionally adding a filming material, the solid tobacco extract, polyhydric alcohols, and metal hydroxides into deionized water, performing gelatinization reaction, degassing under a decompressing condition to obtain a filming solution, unfolding the filming solution on a template, and balancing to obtain the tobacco film suitable for the heated non-combustion tobacco products. The tobacco film prepared by the method can effectively release smoke under a heated non-combustion state, and the released smoke has good sense quality, the smoke releasing quality performance of the tobacco raw material under the heated non-combustion state can be enhanced, the smoke concentration is improved and a good flame retarding action is realized due to the addition of the metal hydroxides.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for preparing a tobacco film suitable for heating non-combustion tobacco products. Background technique [0002] Heat-not-burn tobacco products originated in the 1980s and have a history of nearly 30 years since the products were launched. After continuous technological innovation and product promotion, it has become one of the important types of new tobacco products. The smoke produced by this type of product is closer to that of traditional cigarettes, and the sidestream smoke and some harmful components are significantly reduced, making it have a certain market potential. Therefore, related technologies have become a research hotspot for foreign tobacco companies. In recent years, with the continuous increase of tobacco control efforts, foreign tobacco companies have continuously increased research and development efforts on heat-not-burn tobacco products...
