Preparation of aroma-enhancing and harm-reducing low-temperature fraction and application of aroma-enhancing and harm-reducing low-temperature fraction in cigarette heating

Abstract

The invention belongs to the technical field of cigarette heating, and particularly relates to preparation of aroma-enhancing and harm-reducing low-temperature fractions and application of the aroma-enhancing and harm-reducing low-temperature fractions in cigarette heating. The preparation method comprises the following steps: carrying out reflux extraction on a mixed raw material of Turkey aromatic tobacco leaves and guava leaves by using ethyl acetate so as to obtain a primary extract, wherein the using amount of the ethyl acetate is 10-30 times of the mass of the raw material, the extraction time is 1-3 hours, and the extraction frequency is 2-5 times; fully dissolving the primary extract with 2-5 mass times of ethyl acetate under the heating condition at the temperature of 65-75 DEG C, uniformly stirring, freezing for 10-18 hours at the temperature of-5 to-15 DEG C, and performing suction filtration to obtain filtrate; and extracting acidic components from the filtrate to serve as low-temperature fractions. The low-temperature fractions with aroma enhancement and harm reduction functions are obtained from natural raw materials through reflux extraction and acid-base separation, and when the low-temperature fractions are applied to heated cigarettes, the aroma can be rounded, the aroma can be modified, the smoking flavor can be improved, a product is endowed with a characteristic aroma style, and meanwhile, harmful ingredients such as polycyclic aromatic hydrocarbon and free radicals in smoke of the heated cigarettes can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of heated cigarettes, and in particular relates to the preparation of a low-temperature fraction for increasing flavor and reducing harm and its application in heating cigarettes. Background technique [0002] According to existing literature reports, more than 6,000 chemical components have been identified in traditional cigarette gas. It can be decomposed or combined under certain conditions, so it can be seen that reducing the heating or combustion temperature can significantly reduce the release of harmful components in the smoke. In addition, the sidestream smoke generated after traditional cigarettes are lit (mainly the smoke that escapes from the smoldering end of the cigarette during the puffing interval) will cause passive smoking by non-crowds and arouse disgust among non-smokers. [0003] Smokers are eager to smoke less harmful cigarettes, and non-smokers want to avoid the hazards of passive smok...

AI Technical Summary

Problems solved by technology

At present, tobacco extracts have been widely used in traditional cigarettes, but due to differences in raw materials, limitations in extraction techniques, analysis methods, and use environments, most products are difficult to directly transplant into heated cigarettes to exert their efficacy. The separation method will cause different degrees of damage to the heat-sensitive aromatizing substances, and cannot retain the aromatizing components of tobacco itself
