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

Embodiment 1

[0077] A preparation method of fragrance-loaded supramolecular gel based on nicotine gallic acid salt gelling agent, comprising the steps of:

[0078] Step 1, preparation of the gelling agent: the gallic acid and nicotine are respectively dissolved in a mixed solvent of water and ethanol in a molar ratio of 2:1, and the mass volume ratio of the mixed solvent of gallic acid and the water and ethanol dissolved therein is 1g:28mL The mass volume ratio of nicotine to the water and ethanol that dissolves it is 1g:210mL, and it is stirred at room temperature until it is completely dissolved to obtain gallic acid solution and nicotine solution respectively, and then the above two solutions are fully mixed to obtain a mixed solution, The mixed solution was heated to reflux, reacted for more than 30 minutes, 170 mbar, 53 ° C rotary evaporation, and then the product obtained by the rotary evaporation was dried at 36 ° C for 24 hours to obtain nicotine gallate salt gelling agent. In the ...

Embodiment 2

[0084] This example provides the application of the fragrance-loaded supramolecular gel prepared in Example 1 of the present invention in heating cigarettes

[0085] The nicotine salt supramolecular gel can be respectively applied in the manufacturing process of the reconstituted tobacco leaf for paper-making heated cigarettes and the reconstituted tobacco leaf for heated cigarettes heated by thick pulp method, and can be applied as a single gel or mixed gels of different types according to actual conditions.

[0086] Reconstituted tobacco leaves for paper-making heated cigarettes:

[0087] Method 1: Add the fragrance-carrying supramolecular gel prepared in Example 1 to a certain amount of fuming agent (1,2-propanediol, glycerin or a mixture of the two in a certain proportion), the quality of the fragrance-carrying supramolecular gel and the fuming agent The ratio is 5:1, the temperature is raised to 90°C, the gel melts into a sol state or a solution, and is uniformly mixed to...

Embodiment 3

[0099] This example provides the application of the fragrance-loaded supramolecular gel prepared in Example 1 in electronic cigarettes.

[0100] The nicotine salt supramolecular gel can be applied in electronic cigarettes in two ways, and a single gel or different types of mixed gels can be used according to actual conditions.

[0101] Method 1: Dry the fragrance-carrying supramolecular gel prepared in Example 1 above at a constant temperature in an oven at 40°C for 24-36 hours, grind the dried gel into uniform micro-particles, and add a certain amount of e-cigarette gel in a certain proportion. Fully stir in the fuming agent, the fuming agent is a mixed solvent of glycerin and 1,2-propanediol 1.2:1 (volume ratio), the mass ratio of the fragrance-carrying supramolecular gel to the fuming agent is 1:120, mix well and serve as The flavor-containing gel smoking agent or as an auxiliary material is directly added to the finished e-liquid and mixed uniformly as the flavor-containin...

Abstract

The invention belongs to the field of supramolecular gel, and particularly relates to fragrance-carrying supramolecular gel based on a gallic acid nicotine salt gelling agent. The gel comprises the gallic acid nicotine salt gelling agent, a flavor substance and a solvent, wherein the flavor substance and the solvent are dispersed in the gallic acid nicotine salt gelling agent; and the gallic acid nicotine salt gelling agent is of 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 connection of countless gallic acid nicotine salt supramolecular structure units formed between gallic acid and nicotine. According to the invention, gallic acid and nicotine are used for preparing the gelling agent with the supramolecular network structure and fragrance-carrying supramolecular gel for the first time, and fragrance substances are stably fixed in the gel network at 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, in particular to a fragrance-carrying supramolecular gel based on nicotine gallic acid salt 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 carboxylates include nicotine tartrate, nico...
