Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette oil capable of improving taste and a preparation method thereof. Background Art
[0002] Electronic cigarettes are a new type of tobacco product that produces inhalable aerosols by heating the e-liquid through the atomizer core. It can produce mist like cigarettes. Electronic cigarette oil is the core part of electronic cigarettes, mainly composed of food-grade propylene glycol (also known as glycerin), 1,2-propylene glycol, nicotine, flavors and fragrances. Since it does not produce harmful substances such as tar and carbon monoxide during the smoking process, it greatly reduces potential health risks and provides consumers with a new consumption option.
[0003] Currently in the industry, e-cigarette oils have problems such as low taste restoration, easy aroma attenuation, and insufficient concentration of characteristic aroma. The reason is that most characteristic aroma substances are small molecules, low boiling points, and volatile substances, which are easily affected by light, heat, O2, pH, time, etc., causing some aroma substances to volatilize, dissipate, and oxidize. Summary of the invention
[0004] In order to solve the problems in the prior art, the present invention provides an electronic cigarette oil that can improve the taste, and also provides a preparation method for the electronic cigarette oil that can improve the taste, so as to improve the smoking quality of electronic cigarettes. The present invention not only improves the sustained release and stability of flavor substances, but also improves the restoration, harmony and consistency of the taste during smoking. At the same time, reliability experiments show that microcapsule electronic cigarette oil can reduce taste attenuation, increase the number of puffs, and prolong the life of the heating wire.
[0005] The electronic cigarette oil of the present invention can improve the taste. The electronic cigarette oil is configured with flavor microcapsules. The mass ratio of the electronic cigarette oil to the flavor microcapsules is 1:300-1:700. The flavor microcapsules have the same taste as the electronic cigarette oil.
[0006] Furthermore, the flavor of the flavor microcapsule adopts fruit flavor, including blueberry, strawberry, banana, lemon, cola, peach, and mango fruit flavor. The flavor microcapsule includes a flavor core material containing a set flavor and a wall material wrapping the flavor core material.
[0007] Furthermore, the mass ratio of the electronic cigarette oil to the flavor microcapsules is 1:450-1:600.
[0008] The present invention also provides a method for preparing an electronic cigarette oil, which is used to prepare the electronic cigarette oil capable of improving the taste. The method for preparing the electronic cigarette oil comprises the following steps:
[0009] S1: dissolving the flavor microcapsules in propylene glycol, heating and ultrasonic dissolving, and mixing evenly to obtain a microcapsule solution, wherein the mass ratio of the flavor microcapsules to the volume of propylene glycol is: 0.02-0.24 g: 1 ml;
[0010] S2: Prepare electronic cigarette oil with flavors corresponding to the flavor microcapsules;
[0011] S3: adding the essence microcapsule solution to the electronic cigarette oil at a certain concentration ratio, homogenizing and standing at room temperature to obtain the electronic cigarette oil capable of improving the taste.
[0012] Furthermore, in step S1, the heating temperature is 25-50°C, and the ultrasonic time is 20-50min.
[0013] Furthermore, in step S3, the mass ratio of the flavor microcapsule solution to the electronic cigarette oil is 1:20-1:30.
[0014] Furthermore, in step S3, the mixture is left to stand for 12-24 hours to obtain the electronic cigarette liquid with improved taste.
[0015] Compared with the prior art, the present invention has the following beneficial effects: the present invention adds essence microcapsules with the same taste as the electronic cigarette oil to the electronic cigarette oil, establishes an efficient delivery system for the flavor substances through a unique preparation method and process optimization, controls the slow release of the flavor substances at the molecular level and increases the stability of their chemical functional groups, thereby improving the restoration of the taste during inhalation, the harmony and consistency of the aroma, and achieving the effect of enhancing the flavor and taste;
[0016] In the electronic cigarette oil containing flavor microcapsules of the present invention, the flavor microcapsules exist in the form of micron particles. Compared with the original small molecule structure, the number of puffs can be increased, the flavor decay can be reduced, and the life of the heating wire can be extended. Therefore, the present invention can improve the restoration of the taste of the electronic cigarette at the molecular level when the electronic cigarette is smoked. On the premise of retaining the aroma in the original electronic cigarette oil, the flavor microcapsules that can release the aroma uniformly and reduce the aroma decay are additionally added, which has important practical value and guiding significance for the construction and innovation of the electronic cigarette flavoring system;
[0017] By adding flavor microcapsules to the e-cigarette oil, during the volatilization process of the e-cigarette oil, under the action of the flavor microcapsule microparticles, the adhesion of substances on the heating wire can be reduced, thereby effectively improving the carbon deposition of the heating wire and extending the service life of the heating wire.

[0020] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0021] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.
[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0023] In order to improve the smoking quality of electronic cigarettes, the present invention establishes an efficient delivery system to control the slow release of highly volatile flavors, improves the stability of the chemical functional groups of the flavors, forms a key technical system for enhancing flavor and taste, and improves the restoration of the taste of electronic cigarettes, uniform release of aroma, and reduction of aroma attenuation at a molecular level. It has important practical value and guiding significance for the construction and innovation of electronic cigarette flavoring systems.
[0024] The present invention applies microcapsule technology to electronic cigarette oil, controls the aroma components, delays their volatilization and deterioration process, and realizes the slow and uniform release of aroma substances, thereby achieving the purpose of enhancing flavor and taste. Specifically, the electronic cigarette oil of the present invention is configured with flavor microcapsules, and the mass ratio of the electronic cigarette oil to the flavor microcapsules is 1:300-1:700, and the taste of the flavor microcapsules is consistent with the taste of the electronic cigarette oil. The preferred mass ratio is 1:450-1:600. On the basis of the existing flavor oil, the present invention retains the aroma in the original electronic cigarette oil, and additionally adds flavor microcapsules that can release the aroma uniformly and reduce the aroma attenuation, which can effectively reduce the taste attenuation. The attenuation of the oil during the suction process can be effectively supplemented by the slow release of the flavor microcapsules, thereby maintaining the continuity of the taste and improving the reduction degree of the product.
[0025] The flavor of the flavor microcapsule in this example is preferably fruit flavor, including blueberry, strawberry, banana, lemon, cola, peach, mango and other fruit flavors. The flavor microcapsule includes a flavor core material containing a set flavor and a wall material that wraps the flavor core material. It can be prepared by the existing freeze-drying method, and the component of the wall material is preferably β-cyclodextrin.
[0026] This example also provides a method for preparing the above-mentioned electronic cigarette oil, comprising the following steps:
[0027] S1: dissolving the flavor microcapsules in propylene glycol, heating and ultrasonic dissolving, and mixing evenly to obtain a microcapsule solution, wherein the mass ratio of the flavor microcapsules to the volume of propylene glycol is: 0.02-0.24 g: 1 ml;
[0028] S2: Prepare electronic cigarette oil with flavors corresponding to the flavor microcapsules;
[0029] S3: adding the essence microcapsule solution to the electronic cigarette oil at a certain concentration ratio, homogenizing and standing at room temperature to obtain the electronic cigarette oil capable of improving the taste.
[0030] In step S1, the heating temperature is 25-50°C, and the ultrasonic time is 20-50 min.
[0031] In step S3, the mass ratio of the flavor microcapsule solution to the electronic cigarette oil is 1:20-1:30, and the mixture is allowed to stand for 12-24 hours to obtain the electronic cigarette oil with improved taste.
[0032] In order to further understand and appreciate the preparation process of the present invention and the effects achieved, the present invention is described in detail below in conjunction with embodiments and drawings.
[0033] 1. Solvent selection for flavor microcapsules
[0034] Dissolve 0.5g of flavor microcapsules in 5ml of ethanol, propylene glycol, glycerin and water respectively, and perform ultrasonic dissolution at room temperature. The experimental phenomenon shows that the flavor microcapsules have better solubility in propylene glycol. The results are as follows: Figure 1 As shown, therefore, propylene glycol is preferably used as the solvent for the fragrance microcapsules.
[0035] 2. Selection of Dissolution Temperature of Fragrance Microcapsules
[0036] 0.5g of flavor microcapsules were added with 5ml of propylene glycol, and ultrasonically dissolved at different temperatures (25-50°C). The best dissolution temperature was screened out by observing the dissolution conditions at different temperatures. The specific experimental results are shown in Table 1. When the temperature is higher than 40°C, the flavor microcapsules can be completely dissolved in propylene glycol. Considering that low temperature is conducive to the stability of the microcapsules, 40°C is preferably used as the experimental condition. The size of the flavor microcapsules here is at the micron level and is invisible to the naked eye. They appear to be completely dissolved in the dissolution process, but they still exist in the form of capsules at the microscopic level.
