Supramolecular gel based on three-dimensional network structure

Abstract

The invention belongs to the field of supramolecular gel, and particularly relates to supramolecular gel based on a three-dimensional network structure. The gel comprises a cinnamic acid nicotine salt gelling agent, a flavor substance and a solvent, wherein the flavor substance and the solvent are dispersed in the cinnamic acid nicotine salt gelling agent; and the cinnamic acid nicotine salt gelling agent is of a three-dimensional fiber network structure formed by self-assembly of a one-dimensional fiber network. The specific supramolecular gel system is comprehensively matched with factors such as the thermal stability of the nicotine salt gelling agent, the nicotine release temperature interval, the volatility of flavor substance fixed by the gel, the property of the solvent and the like. Particularly, the semi-volatile fragrant substances are fixed in the cinnamic acid nicotine salt gel which is good in thermal stability (large in Tgel value) and releases nicotine in a high-temperature interval (large in Tic value), and the defect that a large amount of the semi-volatile fragrant substances are released in the front section of smoking and the fragrance is light in the rear section of smoking can be overcome.

Description

technical field [0001] The invention belongs to the field of supramolecular gels, and in particular relates to a supramolecular gel based on a three-dimensional network structure. Background technique [0002] Basic nicotine can react with carboxyl groups of organic acids to form nicotine carboxylate. Nicotine contains a pyridine ring and a pyrrole ring. Among them, the pyrrole ring nitrogen is more basic and tends to react with the carboxyl group of a carboxylic acid to form nicotine salts, while the pyridine ring nitrogen is weaker in basicity and cannot ionize basically. Binds to carboxylic acids through non-covalent interactions such as hydrogen bonds. Tobacco leaves naturally contain various carboxylic acid nicotine salts. According to the acid-base ratio of nicotine salts, nicotine salts can be divided into 1:1 acid-base ratio, 2:1 acid-base ratio, and 3:1 acid-base ratio nicotine salt. Among them, common nicotine carboxylates include nicotine tartrate, nicotine cinn...

Problems solved by technology

[0010] Although nicotine salts have been widely used in e-cigarette liquids, there are still the following main sensory problems in e-cigarettes containing nicotine salts: when nicotine salts are heated and decomposed to form free nicotine and delivered to the atomized vapor, puff-by-puff nicotine The release behavior is inconsistent with the release behavior of the aromatizing ingredients, and it is difficult to achieve the synergistic delivery of the key aromatizing ingredients and nicotine. While bringing nicotine physiological satisfaction, it cannot bring the matching characteristic fragrance, resulting in the interaction between nicotine and flavoring substances. The sensory sensations are strong and weak, covering each other or even repelling each other, especially for volatile characteristic aroma substances, because they cannot be released stably throughout the smoking process (usually the release amount gradually decreases mouth by mouth), this sense of incongruity especially obvious

Another common problem with e-cigarettes is that during the storage of e-liquid or pods, there will inevitably be a problem of volatilization and loss of flavor components. Even closed pods also have the problem of deterioration of flavor substances.

At present, although microcapsule technology can be used to encapsulate volatile aroma components, since microcapsules mostly use sugars such as cyclodextrin as wall materials, there will be a problem caused by the wall material adhering to the heating element at the heating temperature of the electronic cigarette. burnt smell and discomfort
