Description

Technical Field

[0001] The invention relates to the technical field of production of heated cigarette products, and in particular to a step-by-step flavoring method for cooling heated cigarettes based on a "borneol-menthol" low eutectic solvent. Background Art

[0002] Heat-not-burn tobacco (i.e., heated cigarettes) products are a new type of tobacco product that heats tobacco to volatilize and produce nicotine and flavor to meet the needs of smokers. Since heated cigarettes do not require combustion and the heating temperature is low, they can greatly reduce the harmful components produced by combustion. Compared with traditional cigarettes, they are less harmful. In addition, because their taste is similar to that of traditional cigarettes, they have developed rapidly abroad in recent years.

[0003] As a category of new tobacco, cool-type heated cigarettes are favored by consumers in Africa, Southeast Asia and Europe because of their pleasant cool taste and herbal aroma, and have become one of the main products of new tobacco heated cigarettes. The coolant ingredients applied to cool-type heated cigarettes are mostly menthol and alcohol derivatives, which are mostly solid at room temperature and have low solubility in propylene glycol. Cool-type heated cigarettes usually mix mint coolants in the fragrance liquid and add them to the tobacco through the flavoring system. Since the addition ratio of the fragrance liquid is usually 1%-2%, and the solubility of cool-type coolants in propylene glycol is limited, a large amount of solvent is required to ensure the dissolution of mint coolants. Letting it dissolve in the fragrance liquid will greatly increase the flavoring ratio, which is easy to form yellow spots on the surface of the cigarette, affecting the quality of the cigarette; at the same time, the excessive content of propylene glycol solvent also affects the smoking quality of the cigarette, greatly limiting the application of menthol. Therefore, how to add coolants to heated cigarettes is a hot topic in the research of new tobacco heated cigarettes.

[0004] A low eutectic solvent refers to a two-component or three-component low eutectic mixture composed of a hydrogen bond acceptor and a hydrogen bond donor in a certain stoichiometric ratio, and its solidification point is significantly lower than the melting point of each component pure substance. The low eutectic solvent has the characteristics of simple preparation, good solubility, and low volatility, and is mostly used in gas absorption, nanomaterial synthesis, and drug sustained release. For example, Chinese patent CN109171014A proposes a new type of high-efficiency, green and environmentally friendly menthol low eutectic solvent that takes into account the cool suction property of menthol and the moisturizing property of low melting point co-solvents, and wraps it in gelatin or sodium alginate capsule walls to prepare menthol low eutectic solvent moisturizing beads or capsules, and the moisturizing beads are filled into filter rods, providing a method for the application of high-concentration menthol in the tobacco industry. Therefore, the present invention intends to develop a cool-flavored heated cigarette flavoring method to solve the problem that the cool agent is difficult to add and easy to volatilize during the application process.
