Description

Technical Field

[0001] The invention relates to a flavor preparation process, and in particular to a lemon emulsified flavor that can be used for electronic atomization liquid and a preparation method thereof. Background Art

[0002] Electronic atomization liquid has been widely popularized around the world. There are many flavors of electronic atomization liquid on the market. Among them, lemon flavor is loved by many users because of its fresh and refreshing characteristics. In lemon-flavored flavors, limonene, citral and a variety of low-carbon esters are the main flavor substances. Electronic atomization liquid usually uses propylene glycol (PG) and glycerol (VG) as solvents. These two solvents can produce a large amount of smoke when the electronic atomization liquid is heated, giving users a good smoking experience. However, the main flavor substances in lemon flavor have poor solubility in PG and VG. When the addition amount is slightly higher, turbidity and stratification will occur. Therefore, it is necessary to strictly control the upper limit of lemon flavor addition in electronic atomization liquid. When the amount of lemon flavor added is low, the taste of the electronic atomization liquid is not full enough, which will affect the user's smoking experience. Emulsified flavors are processed by appropriate emulsification process under the action of surfactants to evenly disperse the insoluble flavors in the solvent to form a uniform and stable system. Developing a lemon emulsified flavor that can be used in electronic atomizing liquid can effectively increase the amount of lemon flavor added to the electronic atomizing liquid and improve the smoking experience of the lemon-flavored electronic atomizing liquid. Summary of the invention

[0003] The invention provides a lemon emulsified flavor that can be used for electronic atomization liquid and a preparation method thereof. The processing technology is simple and stable. The prepared lemon emulsified flavor is applied to the electronic atomization liquid and has the advantages of high addition amount, uniform and stable system, not easy to stratify, and convenient for long-term storage.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A lemon emulsified flavor that can be used for electronic atomization liquid, characterized in that it comprises the following components in parts by weight: 1 part of lemon flavor, 3-6 parts of low-viscosity solvent A, 2-5 parts of high-viscosity solvent B, 0.5-3 parts of low HLB value emulsifier I and 0.5-3 parts of high HLB value emulsifier II.

[0006] Furthermore, the preparation method of the lemon emulsified essence comprises the following steps:

[0007] S1, weighing lemon flavor and low-viscosity solvent A according to the ratio, adding the flavor into solvent A at room temperature and stirring and mixing, setting the stirring speed to 600-1000 rpm, adding the weighed emulsifier I during the stirring process, stirring for 10-30 minutes, and obtaining a lemon flavor emulsion;

[0008] S2, weighing emulsifier II and high viscosity solvent B according to the ratio, adding emulsifier II into solvent B at room temperature, stirring and mixing, setting the stirring speed to 600-1000 rpm, stirring for 10-30 minutes, and obtaining an emulsifier II solution;

[0009] S3, adding the lemon essence emulsion prepared in step S1 to the emulsifier II solution prepared in step S2 and stirring, setting the stirring speed to 600-1000 rpm, stirring for 30-60 minutes, to perform preliminary emulsification;

[0010] S4, the preliminary emulsion of step S3 is homogenized once and twice by a high-pressure homogenizer, the pressure of the first homogenization is 0.8-1.0MPa, and the pressure of the second homogenization is 1.6-3.0MPa. After the homogenization is completed, it is allowed to stand for 1-5 hours to obtain a lemon emulsified flavor that can be used for electronic atomization liquid.

[0011] In the above preparation method, the emulsifier has the function of reducing the surface tension of the dispersed phase oil particles, making the dispersed phase easy to be mechanically ground, forming a protective film on the surface of the oil phase particles, preventing the dispersed oil phase particles from re-agglomerating, making the oil and water dispersed evenly, and forming a stable and uniform emulsion system. The emulsification effect of using an emulsifier I with a low HLB value and an emulsifier II with a high HLB value in synergy is significantly better than using a single type of emulsifier.

[0012] Optionally, the HLB value of the emulsifier I used in step S1 is in the range of 4-10.

[0013] Optionally, the HLB value of the emulsifier II used in step S2 is in the range of 15-18.

[0014] Optionally, the solvent A used in step S1 is propylene glycol or ethanol; preferably, the solvent A used is propylene glycol.

[0015] Optionally, the emulsifier I used in step S1 is at least one of the sorbitan fatty acid ester emulsifiers Span-20, Span-40, Span-60, and Span-80; preferably, the emulsifier I used is Span-60.

[0016] Preferably, the solvent B used in step S2 is glycerol.

[0017] Optionally, the emulsifier II used in step S2 is a polyoxyethylene sorbitan fatty acid ester emulsifier, which is at least one of Tween-20, Tween-40, Tween-60, and Tween-80; preferably, the emulsifier II used is Tween-20.

[0018] In summary, the present invention has the following beneficial effects:

[0019] 1. The present invention adds two emulsifiers with different HLB values ​​to lemon flavor, and prepares lemon emulsified flavor through two high-pressure homogenizations. The preparation method is simple, and the product has good uniformity and stability.

[0020] 2. The lemon emulsified flavor prepared by the present invention can be used in electronic atomization liquid. When added in high amounts, turbidity and stratification problems will not occur, which effectively solves the application limitations of traditional lemon flavor in electronic atomization liquid.
