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 extract spice, an effective part extract of a non-tobacco plant, a synthetic edible spice and natural nicotine are mixed to prepare the electronic atomized liquid, however, compared with the traditional cigarette, a single variety of tobacco extracts still has a lack of aromatic components, and the composite flavoring is also prone to have problems of poor harmony, unstable flavor and the like, the release behaviors of the flavor components from different sources are inconsistent, the synchronous delivery of the plant spice and the endogenous flavor components of tobacco is difficult to realize, a phenomenon of flavor separation or covering may occur in the smoking process, and the smoking experience of consumers is affected.
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.
Disclosure of Invention
Aiming at the technical problems, the invention provides the natural and healthy electronic atomized liquid with rich and lasting taste, and the aging process integrates strong fruit fragrance, fragrant flower fragrance, wood fragrance and tobacco fragrance, thereby providing unique smoking experience.

an electronic atomized liquid with rich and durable mouth feel consists of 0.1-10 wt% of tobacco essence and 90-99.9 wt% of solvent, wherein the tobacco essence is prepared from a tobacco fragrance light component and a plant natural perfume; the cigarette fragrance light component is prepared by taking waste and inferior tobacco stems and tobacco leaves as raw materials through alkali pretreatment, fermentation, filtration and molecular distillation.
Natural and rich tobacco fragrance and plant fragrance are difficult to restore through blending of synthetic spices, and the smoking experience is influenced due to single fragrance structure or excessive essence odor. The tobacco essence disclosed by the invention combines the tobacco refined substance and the plant natural perfume, so that the problem of insufficient tobacco fragrance of the electronic atomizer can be well solved, and meanwhile, the natural perfume is only added, so that the tobacco essence is healthier, has stronger natural feeling and richer smoking taste.
The invention uses waste tobacco stems and tobacco leaves as raw materials, adopts a microbial fermentation technology to enrich aroma substances, and then uses molecular distillation to enrich small molecular aroma substances and remove miscellaneous gases or substances with unpleasant odor, so that the aromatic smell of the tobacco can be provided, meanwhile, the light components of the tobacco aroma also contain a small amount of nicotine, so that the invention has better addiction-removing property, can meet the pursuit of consumers on throat feeling and brings better physiological pleasure. Meanwhile, the electronic atomized liquid of the invention can be added with no nicotine or nicotine salt, which is beneficial to relieving the dependence of consumers on nicotine and reducing the harm to human bodies.
The waste and inferior tobacco stems and tobacco leaves are renewable organic resources, the lignin components in the waste and inferior tobacco stems and tobacco leaves prevent cellulose from contacting cellulase, so that difficulty is caused in secondary utilization, the lignin in the raw materials can be removed after alkaline pretreatment, the accessibility of the enzyme and a substrate is promoted, and full fermentation is facilitated. Meanwhile, alcohol substances such as ethanol and the like generated by fermentation are compounded with the plant natural perfume to generate more fragrant components through esterification, condensation and other reactions, so that the fragrance is richer and fuller.
