Problems solved by technology

At the same time, the surfactant and co-surfactant system used in the above patents are used in the preparation of the linoleic acid microemulsion carrier, and a uniform and transparent microemulsion system cannot be obtained (see Comparative Example 1). Therefore, it is necessary to find a suitable food-grade sub- Oleic acid microemulsion carrier

Embodiment 1

[0027] The components and weight percentages of the food-grade linoleic acid microemulsion carrier in this embodiment are: Tween20 ethanol mixture 18%, linoleic acid 2%, water 80%, and the mass ratio of Tween20 to ethanol is 4:1. The preparation method of the linoleic acid microemulsion carrier in this example is as follows: under the condition of continuous stirring, the stirring rate is 100 rpm, and the Tween20 ethanol mixture is added to the mixing kettle first, then linoleic acid is added, and finally water is added to obtain a clear A transparent and uniform system is the desired microemulsion system.

[0028] The stability of the particle size of the microemulsion carrier of this example was followed up. The microemulsion of this example was stored at room temperature and protected from light, and the particle size was measured every 3 days. The results of the change in particle diameter of the microemulsion of the example within 30 days are shown figure 2 . After 30 day...

Embodiment 2

[0030] The components and weight percentages of the food-grade linoleic acid microemulsion carrier in this embodiment are: Tween20 ethanol mixture 16%, linoleic acid 4%, water 80%, and the mass ratio of Tween20 to ethanol is 3:2. The preparation method of the linoleic acid microemulsion carrier in this example is as follows: under the condition of continuous stirring, the stirring rate is 100 rpm, and the Tween20 ethanol mixture is added to the mixing kettle first, then linoleic acid is added, and finally water is added to obtain a clear A transparent and uniform system is the desired microemulsion system.

[0031] The stability of the particle size of the microemulsion carrier of this example was followed up. The microemulsion of this example was stored at room temperature and protected from light, and the particle size was measured every 3 days. The results of the change in particle diameter of the microemulsion of the example within 30 days are shown figure 2 . After 30 day...

Embodiment 3

[0033] In this embodiment, the components and weight percentages of the food-grade linoleic acid microemulsion carrier are: Tween20 ethanol mixture 14%, linoleic acid 6%, water 80%, and the mass ratio of Tween20 to ethanol is 4:1. The preparation method of the linoleic acid microemulsion carrier in this example is as follows: under the condition of continuous stirring, the stirring rate is 100 rpm, and the Tween20 ethanol mixture is added to the mixing kettle first, then linoleic acid is added, and finally water is added to obtain a clear A transparent and uniform system is the desired microemulsion system.

[0034] The stability of the particle size of the microemulsion carrier of this example was followed up. The microemulsion of this example was stored at room temperature and protected from light, and the particle size was measured every 3 days. The results of the change in particle diameter of the microemulsion of the example within 30 days are shown figure 2 . After 30 da...

Abstract

The invention discloses a food-grade linoleic acid micro-emulsion carrier and a preparation method of the food-grade linoleic acid micro-emulsion carrier. The food-grade linoleic acid micro-emulsion carrier comprises the following components in parts by weight: 0.5-20 parts of Tween20 ethanol mixture, 0.5-9 parts of linoleic acid and 71-99 parts of water. The preparation method of the micro-emulsion carrier specifically comprises the following steps of: under the condition of continuous stirring, adding the Tween20 ethanol mixture at certain proportion into a mixing kettle according to the parts by weight; and adding the linoleic acid and finally adding water to obtain a clear transparent uniform system which is the required micro-emulsion carrier. Through the invention, the problem that linoleic acid is insoluble to water is solved, and the dispersity of linoleic acid is improved by reducing the particle size of linoleic acid micro-emulsion.

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 a food-grade linoleic acid microemulsion carrier and a preparation method thereof. Background technique [0002] Linoleic acid is a functional polyunsaturated fatty acid, which has the effect of lowering serum cholesterol levels. Intake of large amounts of linoleic acid has obvious effects on high triglyceride diseases. The Chinese Pharmacopoeia still uses ethyl linoleate pills and drops as drugs for the prevention and treatment of hypertension, atherosclerosis, and coronary heart disease. Linoleic acid helps to reduce serum cholesterol and inhibit the formation of arterial thrombosis, so it has a good effect in preventing cardiovascular diseases such as atherosclerosis and myocardial infarction. In addition, linoleic acid is also a precursor of omega-6 long-chain polyunsaturated fatty acids, especially γ-linolenic acid and ar...
