Preparation of low temperature fraction with aromatizing function applied to heated cigarette and its use in heated cigarette

Abstract

The invention belongs to the technical field of heated cigarettes, and in particular relates to a preparation method of a low-temperature fraction with aromatizing function applied to heated cigarettes and its use in heated cigarettes. The preparation method includes the following steps: the raw materials include: 15wt% Zimbabwe tobacco leaves, 25wt% Baoshan oriental tobacco leaves, 25wt% Xinjiang oriental tobacco leaves, 10wt% Turkish oriental tobacco leaves, 5wt% Honghe Luxi Hongda tobacco leaves, and 20wt% Kunming Shilin tobacco leaves. The ratio of raw material to water mass is 1:2.5. The raw material is wetted with water, put into a microwave extraction device, the extraction power is 520W, and the extraction time is 65min. After the extraction is completed, the extract in the separation kettle is collected. Under the conditions of room temperature and operating pressure of 0.16-0.18MPa, the crude extract is filtered with an ultrafiltration membrane with a molecular weight of 10,000 to 30,000 to obtain a low-temperature fraction. The low-temperature fraction of the invention is added to the heated cigarette for smoking, the aroma quantity is obviously increased, and the aroma is full.

Description

technical field [0001] The invention belongs to the technical field of heated cigarettes, and in particular relates to a preparation method of a low-temperature fraction with aromatizing function applied to heated cigarettes and its use in heated cigarettes. Background technique [0002] According to existing literature reports, more than 6,000 chemical constituents have been identified in traditional cigarette smoke. These chemical constituents are mainly generated by direct transfer of related constituents in tobacco or by pyrolysis and thermal synthesis reactions. Therefore, it can be seen that reducing the heating or combustion temperature can significantly reduce the release of harmful components in the flue gas. In addition, the sidestream smoke generated after traditional cigarettes is lit (mainly the smoke smoldering and escaping from the ignited end of the cigarette during the smoking interval) will cause passive smoking by non-smokers and cause resentment among non...

Problems solved by technology

[0007] In order to improve the smoking quality of heated cigarettes, the present invention extracts and separates low-temperature new latent aroma substances from natural tobacco raw materials to solve the problem of controlled release of flavors and fragrances in heated cigarettes, endows products with characteristic aroma styles, and ensures uniformity before and after smoking. It is a new type of low-temperature spice with aroma-enhancing function
