[0001] The present invention relates to the technical field of electronic cigarette preparation, and in particular to a compound for improving fruit flavor and smoking taste and a preparation method thereof. Background Art

[0002] The formula of a composite fruit-flavored electronic cigarette oil with the publication number CN105167169B is mainly composed of ethyl acetate, raspberry ketone, ethyl heptanoate, phenylethyl alcohol, ethyl acetoacetate, ethyl butyrate, nerolidol, ethyl maltol, geraniol, propyl hexyl lactone, methyl furfural, butyl decalactone, ethyl tetradecanoate, ethyl phenylethyl acetate, lactic acid, menthol, methyl salicylate and other ingredients. The obvious advantage of the electronic cigarette oil prepared with the above ingredients is that it is based on a variety of ester flavors, supplemented by sweet, floral, milky, and fresh flavors to prepare composite fruit-flavored electronic cigarette oil. When the oil is used for electronic cigarette smoking, it can give the smoke a sweet, milky, floral, and fruity aroma. Its fragrance is compounded with the aroma of fruits such as apples and pears, and the aroma is rich and full, and the aftertaste is natural and comfortable. The formula composition of the oil is synthetic or isolated spices, the raw materials are generally easy to obtain, the properties are stable, the preparation is simple, and it has broad application prospects.

[0003] After exploration and analysis, the patent has the following shortcomings when actually used:

[0004] The formula contains edible flavors such as ethyl acetate, raspberry ketone, ethyl heptanoate, phenylethyl alcohol, ethyl acetoacetate, ethyl butyrate, nerolidol, ethyl maltol, geraniol, propyl caprolactone, methyl furfural, and butyl decanolactone. The addition of more additives greatly reduces the safety of e-cigarette smoking. Compared with fruits, these edible flavors do not contain any actual material components related to fruits. They are only used to simulate the taste and smell of fruits, and it is difficult to improve the taste of e-cigarettes.

[0005] In summary, the present application now proposes a compound for improving fruit flavor and smoking taste and a preparation method to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a compound for improving the fruit flavor and the mouthfeel of smoking and a preparation method thereof, which can solve the problem that the formula contains ethyl acetate, raspberry ketone, ethyl heptanoate, phenylethyl alcohol, ethyl acetoacetate, ethyl butyrate, nerolidol, ethyl maltol, geraniol, propyl hexyl lactone, methyl furfural, butyl decanolactone and other edible flavors, and the addition of more additives greatly reduces the safety of electronic cigarette smoking. Moreover, compared with fruits, these edible flavors do not contain any actual material components related to fruits, but are only used to simulate the taste and smell of fruits, and it is difficult to improve the edible taste of electronic cigarettes.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a compound for improving fruit flavor and smoking taste, comprising the following formula raw materials: 30-50 parts of pomelo, 40-60 parts of mango, 40-60 parts of strawberry, 35-55 parts of grapefruit, 30-50 parts of orange, 60-120 parts of glycerin, 60-120 parts of propylene glycol, 20-30 parts of glycerin, 0-10 parts of acidity regulator, and 2-8 parts of regulator. By extracting pomelo, mango, strawberry, grapefruit, and orange, corresponding fruit extracts are formed. By consuming these fruit extracts, compared with synthetic edible flavors, when performing subsequent processing of electronic cigarettes, the ingredients contained in the electronic cigarettes are more natural and healthy, and the fruit extracts can provide rich taste and fragrance for the electronic cigarettes, making the user experience richer and more pleasant, and further improving the sales of electronic cigarettes.

[0008] Preferably, the acidity regulator is citric acid. By adding a proper amount of the acidity regulator, the taste can be improved and the taste can be made fresher.

[0009] Preferably, the regulator is a mint flavor. By adding a mint flavor regulator, the mint flavor can enhance the taste and make the taste more fresh and refreshing. By adding citric acid and a mint flavor regulator, citric acid and mint are common flavor additives, which can provide a fresh and refreshing taste for electronic cigarettes. Citric acid can make the electronic cigarette liquid contain a sour taste, and the mint flavor can give the smoke a cool feeling, which may be a pleasant experience for smokers. The addition of these two flavors can increase the attractiveness of electronic cigarettes.

[0010] A method for preparing a compound for improving fruit flavor and smoking taste comprises the following steps:

Make sure the inside of the fruit basket is dry to avoid moisture on the fruit surface. Then put all the fruit in the fruit basket into the hair dryer and lay the fruit flat on the hair dryer. Let the hair dryer gently dry the fruit surface at a low temperature. When drying the fruit surface, make sure the distance is appropriate to avoid damage to the fruit. After the fruit is dried, lay absorbent materials on the surface of the fruit, such as absorbent paper towels or kitchen paper, to absorb excess moisture and keep the fruit surface dry.

[0013] Method 3: Extraction of fruit components: Chop the washed fruit into small pieces, put the chopped fruit into the extractor of the supercritical extraction equipment, and select a suitable solvent to be poured into the extraction equipment. Commonly used supercritical solvents include carbon dioxide (CO2) and ethanol. CO2 is usually used to extract fat-soluble components, while ethanol is more suitable for extracting polar components. Then set the operating parameters of the supercritical extraction equipment. The parameters generally include temperature and pressure. The temperature is generally controlled between 40°C and 80°C to ensure that the solvent is in a supercritical state, but it is also necessary to avoid damage to the heat-sensitive components in the fruit. The pressure is generally controlled between 100 and 500. A higher pressure helps to improve the extraction efficiency and speed, but safety must also be paid attention to. Then select a suitable solvent for extraction to form a fruit extract after extraction;

[0014] Method 4, mixing formula: the extracted fruit extract is introduced into a mixing device, and glycerin, propylene glycol, citric acid and mint flavor regulator are placed in the device at the same time, and the workbench and mixing equipment are ensured to be clean to prevent contamination by impurities, and then the mixing device is controlled to start, and the stirring and mixing process is started. During the mixing process, the temperature in the mixing device is monitored to ensure that the mixing temperature is within an appropriate range, so that the fruit extract is mixed with glycerin and propylene glycol;

[0015] Method 5, solution filtration: Before the mixed fruit extract, glycerin and propylene glycol mixture is loaded into the filtering device, it is first subjected to a coarse filtration or pretreatment to remove large particles or impurities to prevent clogging of the filter. Then, the coarsely filtered fruit extract, glycerin and propylene glycol mixture is loaded into the filtering device. When using, ensure that the filtering device is clean, control the filter device to start, and filter the mixture, thereby improving the purity and stability of the mixture and reducing the possibility of impurities appearing inside it.

[0016] Method 6: Packaging and storage: Load the filtered fruit extract, glycerin and propylene glycol mixture into the filling machine. Sterilize the packaging container when using it to ensure that the product is not contaminated by bacteria during the packaging process. After canning, store the canned mixture to facilitate subsequent processing.

[0017] Preferably, before the fruit in the method 1 is prepared, fresh fruit needs to be selected as the extraction raw material to ensure the purity of the fruit flavor.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The compound for enhancing fruit flavor and smoking mouthfeel and the preparation method thereof, in terms of raw materials, extracts pomelo, mango, strawberry, grapefruit and orange to form corresponding fruit extracts. By consuming these fruit extracts, compared with synthetic edible flavors, during the subsequent processing of electronic cigarettes, the ingredients contained in the electronic cigarettes are made more natural and healthy. In addition, the fruit extracts can provide the electronic cigarettes with a rich taste and fragrance, making the user experience richer and more pleasant, further increasing the sales of electronic cigarettes.

[0020] (2) The compound and preparation method for enhancing the fruity flavor and the mouthfeel of the smoker include adding citric acid and mint flavor regulators.
