Embodiment 1

[0058] Get walnut oil 20g, select Brij56 and Tween 80 as composite emulsifier, co-emulsifier selects n-propanol, the ratio of emulsifier and co-emulsifier is 2: 1, get the total amount of composite emulsifier and co-emulsifier to be 30g, After stirring and mixing, add water to dilute and stir and mix for later use. The add-on of water is 65g, and it is packed in a brown glass bottle according to the required dose, so that the O / W walnut oil microemulsion of the present invention is obtained.

[0059] The particle size of O / W walnut oil microemulsion was measured by Nano-Zs90 particle size analyzer, the measured particle size range was 10-80nm, and the average particle size was 26nm.

[0060] The stability of the walnut oil microemulsion was measured, and no delamination or flocculation occurred after storage at room temperature for 3, 6, 9, and 12 months.

[0061] The encapsulation efficiency of the walnut oil microemulsion was determined by static headspace gas chromatography...

Embodiment 2

[0063] Get 20g of walnut oil, select PEG 40 and Tween 80 with a mass ratio of 1:1 as the compound emulsifier, select n-hexanol as the co-emulsifier, the ratio of the compound emulsifier and the co-emulsifier is 2:1, take the compound emulsifier and co-emulsifier The total amount of the agent is 20g. After stirring and mixing, add water to dilute and stir to mix for use. The amount of water added is 60g, and it is divided into brown glass bottles according to the required dose, so that the O / W walnut of the present invention is obtained. oil microemulsion.

[0064] Adopt Nano-Zs90 particle size analyzer to measure the particle size of O / W walnut oil microemulsion, the measured particle size range is 10-70nm, and the average particle size is 26nm, as figure 2 shown.

[0065] The stability of the walnut oil microemulsion was measured, and no delamination or flocculation occurred after storage at room temperature for 3, 6, 9, and 12 months.

[0066] The encapsulation efficiency...

Embodiment 3

[0068] Get 10g of walnut oil, select PEG 40 and lecithin with a mass ratio of 1:1 as the compound emulsifier, select n-hexanol as the co-emulsifier, and the ratio of the compound emulsifier and the co-emulsifier is 2:1, take the compound emulsifier and co-emulsifier The total amount of the agent is 20g. After stirring and mixing, add water to dilute and stir to mix for use. The addition of water is 70g, and it is divided into brown glass bottles according to the required dose, and the O / W walnut of the present invention is obtained. oil microemulsion.

[0069] The average particle diameter was measured to be 27 nm.

[0070] The walnut oil microemulsion was stored at room temperature for 12 months without delamination or flocculation.

[0071] The encapsulation efficiency was measured to be 84%.

Abstract

The invention relates to a method for preparing microemulsion of walnut oil, which uses a primary emulsifier and a secondary emulsifier, and comprises a step of emulsifying and a step of mixing with water for preparing oil/water (O/W) type microemulsion of walnut oil. The prepared microemulsion of walnut oil can solubilize the walnut oil, remove the fishy smell of the walnut oil, reduce the oxidation of unsaturated fatty acid in walnut oil, and retain the nutritional value of the walnut oil; therefore, the prepared microemulsion of walnut oil can improve the quality of products and the biological utilization rate of nutrients, and enlarges the range of applications of the products in the fields of functional drinks, liquid health-care products, functional food ingredients and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of microemulsion preparation. More specifically, the present invention relates to a preparation method of walnut oil microemulsion, and the walnut oil microemulsion prepared by said method. 【Background technique】 [0002] The content of unsaturated fatty acids in walnut oil accounts for more than 90%, which is rich in linoleic acid and linolenic acid. Walnut oil can lower serum cholesterol. It plays an important role in synthesizing phospholipids, forming cell structure, maintaining the normal physiological functions of all tissues, preventing the increase and deposition of cholesterol in serum, softening blood vessels, and preventing hypertension and heart disease. In addition, linoleic acid can also make the skin smooth and delicate, enjoying the reputation of "skin beautifying acid". Walnut oil can be used medicinally and ediblely. It can be used as nutritional oil for the elderly and infants. It can ...
