Description

Technical Field

[0001] The invention relates to the technical field of tobacco flavors and fragrances, and in particular to a method for preparing a heavy mint flavor by utilizing a low eutectic long-acting cooling agent and an application of the same in heated cigarettes. Background Art

[0002] Heat-not-burn tobacco (i.e. heated cigarettes) products are a kind of product that heats the air flowing through it with a high-temperature heat source and uses the hot air to distill the tobacco filling behind the heat source to meet the requirements of smoking. Its maximum temperature is not higher than 500°C. Through the heat conduction function of the heat source, the smoke produced by consumers' inhalation can meet the consumers' smoking habits and reduce the possibility of harmful substances produced by high-temperature combustion of cigarettes. In recent years, due to the growth of consumers' health awareness, heated cigarettes have become the focus of attention in the field of tobacco products at home and abroad.

[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. In heavy mint flavored heated cigarettes, a large amount of solvent is required to ensure the dissolution of mint-type coolants, resulting in a significant increase in the flavoring ratio, from the commonly used 1%-2% to a maximum of 7%, which is easy to form yellow spots on the surface of the cigarette; at the same time, the excessively high content of propylene glycol solvent also affects the smoking quality of cigarettes, greatly limiting the development of heavy mint flavored heated cigarettes.

[0004] Therefore, the present invention intends to develop a method for preparing a heavy mint flavor essence using a low eutectic long-acting cooling agent, so as to solve the problem that cooling agents cannot be used in large quantities during the development and application of cigarettes.
