preparation example Construction

[0020] The invention provides a method for preparing an emulsion system, the specific steps comprising:

[0021] 1) mixing lysine-tyrosine-tryptophan tripeptide with distilled water to obtain tripeptide aqueous solution;

[0022] 2) Under the conditions of an ice-water bath and high-field-strength ultrasound, the tripeptide aqueous solution obtained in step 1) is emulsified with the oil phase to obtain an emulsion system; the field strength of the high-field-strength ultrasound is 10 to 1000 W·cm -2 .

[0023] The invention mixes the lysine-tyrosine-tryptophan tripeptide with distilled water to obtain tripeptide aqueous solution. In the present invention, the mass ratio of the lysine-tyrosine-tryptophan tripeptide to distilled water is preferably 1-10 mg: 1 mL, more preferably 6-9 mg: 1 mL, most preferably 8 mg: 1 mL . The present invention does not have any special limitation on the source of the lysine-tyrosine-tryptophan tripeptide, and commercially available products we...

Embodiment 1

[0034] Take 4 mg of lysine-tyrosine-tryptophan tripeptide in a 1.5 mL centrifuge tube, add 1 mL of distilled water and vortex on a vortex mixer for 5 min; A small probe with a diameter of 3mm is installed on the equipment, the ultrasonic frequency is set to 20kHz, the ultrasonic intensity is 300W, the centrifuge tube is fixed, and kept in an ice-water bath, and the emulsion system is obtained after ultrasonic treatment for 10s.

[0035] After the emulsion system was prepared, the particle size was measured by a Mastersizer 2000 laser particle size distribution analyzer, expressed by volume-average diameter (D43). Particle size is the average of 3 readings, as shown in Table 1. The measurement parameters are as follows: refractive index: 1.450, absorption parameter: 0.010, rotational speed: 2000r / min.

Embodiment 2

[0037] Take 6 mg of lysine-tyrosine-tryptophan tripeptide in a 1.5 mL centrifuge tube, add 1 mL of distilled water and vortex on a vortex mixer for 4 min; A small probe with a diameter of 4mm is installed on the equipment, the ultrasonic frequency is set to 18kHz, the ultrasonic intensity is 400W, the centrifuge tube is fixed, and kept in an ice-water bath, ultrasonically treated for 8s to obtain the emulsion system. After the emulsion system was prepared, the particle size was measured by the particle size measurement method in Example 1, and the results are shown in Table 1.

Abstract

The invention provides a method for preparing an emulsion system, which belongs to the technical field of emulsion preparation. The specific steps include: mixing lysine-tyrosine-tryptophan tripeptide with distilled water to obtain a tripeptide aqueous solution; and under high-field-strength ultrasonic conditions, emulsify the tripeptide aqueous solution and the oil phase to obtain an emulsion system; the field strength of the high-field-strength ultrasonic is 10-1000W·cm ‑2 . The present invention adopts three kinds of tripeptides formed by lysine, tyrosine and tryptophan widely existing in nature as raw materials, and has high safety; the ice water bath can avoid the denaturation of the tripeptide, and guarantee the stability of the tripeptide structure; The tripeptide, distilled water and oil phase are mixed and emulsified under field-strength ultrasound, and the prepared emulsion system has stable performance and good emulsification. It can be seen from the examples that the emulsion system obtained by the preparation method of the present invention has small particle size, stable performance and good emulsification effect when placed at room temperature; the embedding rate of β-carotene reaches 90.2%.

Description

technical field [0001] The invention relates to the technical field of emulsion preparation, in particular to an emulsion system and a preparation method thereof. Background technique [0002] Emulsions are widely used in the food field. It uses emulsifiers to stabilize the oil phase and water phase, thereby forming a relatively stable dispersion system. Many ingredients in food, such as oils, flavor substances, and antioxidants, are hydrophobic. The emulsion-based delivery system can make these hydrophobic substances play a good delivery effect, improve product stability, and provide a good solution for fat-soluble substances. Solubilization provides the environment. [0003] Existing emulsifiers, such as sodium dodecyl sulfate (SDS), are toxic and cannot be used in food; while emulsifiers commonly used in food, such as Tween and Span, are mostly of chemical origin, and consumers are more concerned about them. There are concerns about safety. Therefore, consumers are mor...
