Embodiment 1

[0020] The components and percentages by weight of the O / W type food-grade conjugated linoleic acid microemulsion carrier in this embodiment are: Tween80 / EL35 / ethanol / n-butanol 16.8%, conjugated linoleic acid 7.2%, water 76 %, wherein the mass ratio of Tween80 / EL35 / ethanol / n-butanol is 1:1:1:1. The preparation method of the conjugated linoleic acid microemulsion carrier in this example is: under the condition of continuous stirring, the stirring rate is 100rpm, first add Tween80 / EL35 / ethanol / n-butanol into the mixing kettle, and then add the conjugated linoleic acid Add linoleic acid to water at the end to obtain a clear, transparent and uniform system, which is the desired microemulsion system.

[0021] The stability of conjugated linoleic acid in the microemulsion carrier of this example and the control solution was compared. The control solution is an ethanol solution, and the mass fraction of conjugated linoleic acid in the carrier and the control is 6.8%. The results are...

Embodiment 2

[0023] The components of the O / W type food-grade conjugated linoleic acid microemulsion carrier in this embodiment and their weight percentages are: Tween80 / EL35 / ethanol / n-butanol 19.2%, conjugated linoleic acid 4.8%, water 76 %, wherein the mass ratio of Tween80 / EL35 / ethanol / n-butanol is 1:1:1:1. The preparation method of the conjugated linoleic acid microemulsion carrier in this example is: under the condition of continuous stirring, the stirring rate is 100rpm, first add Tween80 / EL35 / ethanol / n-butanol into the mixing kettle, and then add the conjugated linoleic acid Add linoleic acid to water at the end to obtain a clear, transparent and uniform system, which is the desired microemulsion system.

Embodiment 3

[0025] The components of the O / W type food-grade conjugated linoleic acid microemulsion carrier in this embodiment and their weight percentages are: Tween80 / EL35 / ethanol / n-butanol 21.6%, conjugated linoleic acid 2.4%, water 76% %, wherein the mass ratio of Tween80 / EL35 / ethanol / n-butanol is 1:1:1:1. The preparation method of the conjugated linoleic acid microemulsion carrier in this example is: under the condition of continuous stirring, the stirring rate is 100rpm, first add Tween80 / EL35 / ethanol / n-butanol into the mixing kettle, and then add the conjugated linoleic acid Add linoleic acid to water at the end to obtain a clear, transparent and uniform system, which is the desired microemulsion system.

Abstract

The invention discloses an O / W type conjugated linoleic acid micro emulsion carrier and a preparation method thereof, belonging to the field of food technology. The micro emulsion carrier comprises the following components in percentage by weight: 1%-30% of mixture, 1-13% of conjugated linoleic acid and 57-98% of water, wherein, the mixture is composed of the following components according to the mass ratio of 1:1:1:1: Tween 80, EL35, alcohol and n-caprylic alcohol. The preparation method of the micro emulsion carrier comprises the following steps: under the condition of continuously stirring, the mixture composed of Tween 80, EL35, alcohol and n-caprylic alcohol is added in a mixed kettle in percentage by weight firstly; then the conjugated linoleic acid is added; and finally, water is added to obtain a clear, transparent and even system, namely the required micro emulsion carrier. The invention not only solves the difficulty of low solubility of conjugated linoleic acid in water, but also greatly improves the stability of the conjugated linoleic acid.

Description

technical field [0001] The invention relates to a microemulsion carrier in the field of food technology and a preparation method thereof, in particular to an O / W (oil-in-water) type food-grade conjugated linoleic acid microemulsion carrier and a preparation method thereof. Background technique [0002] Conjugated linoleic acid, namely conjugated octadecadienoic acid, is a general term for a group of various geometric and positional isomer mixtures of linoleic acid containing conjugated double bonds. Conjugated linoleic acid has excellent physiological effects. It can not only enhance immunity, lower blood pressure, shape body and lose weight, but also has unique anti-cancer functions such as inhibiting skin cancer, gastric cancer, and intestinal cancer, which are rare among polyunsaturated fatty acids. It is a new type of Functional food factors have broad application prospects in the fields of medicine, food, biology, and breeding. They are one of the new research hotspots ...
