Fragrance-carrying supramolecular gel based on equal-acid-base-ratio racemic mandelic acid nicotine salt gelatinizing agent

Abstract

The invention belongs to the field of supramolecular gel, and particularly relates to fragrance-carrying supramolecular gel based on an equal-acid-base-ratio racemic mandelic acid nicotine salt gelatinizing agent. The gel comprises a racemic mandelic acid nicotine salt gelatinizing agent, and a flavor substance and a solvent which are dispersed in the racemic mandelic acid nicotine salt gelatinizing agent, wherein the racemic mandelic acid nicotine salt gelatinizing agent is a three-dimensional fiber network structure formed by self-assembly of a one-dimensional fiber network, and the one-dimensional fiber network structure is formed by connecting countless racemic mandelic acid nicotine salt supramolecular structure units formed between racemic mandelic acid and nicotine. According to the invention, racemic mandelic acid and nicotine are used for preparing a gelatinizing agent with a supramolecular network structure and fragrance-carrying supramolecular gel for the first time, and fragrance substances are stably fixed in a gel network at a normal temperature so that the storage stability of aroma components is effectively improved; and common fixation and synergistic release of nicotine and aroma components are realized.

Description

technical field [0001] The invention belongs to the field of supramolecular gels, and in particular relates to a fragrance-carrying supramolecular gel based on an equal-acid-base ratio racemic nicotine mandelate gelling agent. 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 carbox...

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
