Description

Electronic atomized liquid with rich and durable mouth feeling and preparation method thereof

Technical Field

The invention relates to the technical field of electronic atomized liquid, in particular to electronic atomized liquid with rich and durable mouth feel and a preparation method thereof.

Background

With the enhancement of health consciousness of people, the traditional cigarette is gradually replaced by new products such as an electronic nicotine delivery system, a cigarette which is not burnt by heating and the like because a large amount of toxic substances such as tar, smoke and the like are generated in the heating and burning process. The electronic atomization liquid is atomized to form aerosol by heating, so that the harmfulness of the cigarette is greatly reduced compared with that of the traditional cigarette. Most of the electronic atomization liquid is prepared by adding essence, spice, nicotine or nicotine salt and the like to simulate the taste and the aroma of cigarettes. Although the electronic atomization liquid sold in the market at present has a plurality of varieties and tastes, the source, the composition and the release behavior of the aroma substances of the electronic atomization liquid are different from those of cigarettes, so that the electronic atomization liquid has larger difference from the traditional cigarette smoking sensory effect, and cannot meet the pursuit of consumers on natural feeling and smoking quality particularly in the aspects of smoke characteristics, aroma style, comfort level and the like.

The traditional cigarette has complex aroma components, the tobacco flavor spice prepared by manual blending is difficult to restore the real cigarette aroma, the chemical smell of the product of the synthetic spice is obvious, the aroma structure is simple, the taste is numerous but the discrimination is low, the smoking experience is single, and the phenomenon of uneven aroma release is often generated when the electronic atomization device is heated. The tobacco refined product is also an important fragrant raw material in the preparation of tobacco essence, can strengthen the tobacco fragrance to a certain extent, can make up the deficiency of the tobacco fragrance especially when being used in electronic atomization liquid, and enriches the smoking taste and mouthfeel. In order to obtain higher flavor fidelity, natural tobacco extracts are often added into electronic atomized liquid in the prior art, for example, in patent CN103919274B, a tobacco liquid extraction perfume, an effective part extract of a non-tobacco plant, a synthetic edible perfume and natural nicotine are mixed to prepare the electronic atomized liquid, however, compared with the traditional cigarette, the aromatic components of a single variety of tobacco extracts are still lost, and the problems of poor harmony, unstable fragrance and the like are easily caused by compound perfuming, the release behaviors of the fragrant components from different sources are inconsistent, the synchronous delivery of the plant perfume and the endogenous fragrant components of tobacco is difficult to realize, the phenomenon of fragrance separation or covering may occur in the smoking process, and the smoking experience of consumers is influenced.

The microbial fermentation technology is applied to research and development of tobacco flavors and fragrances, screening of aroma-producing strains, extraction and treatment of tobacco and other plant raw materials are the main research directions in China at present, and some synthetic products based on biological fermentation show good effects in cigarette flavoring. If the endogenous fragrant components of the tobacco and other natural spices are compounded and added into the electronic atomization liquid, the natural feeling can be enhanced, the smoking quality can be improved, but the purification difficulty of the natural spices is high, and the generated smell is not lasting, so that consumers cannot well feel satisfied and pleasant.
