Embodiment 1

[0015] Example 1, the oil rich in unsaturated fatty acids is obtained according to the following preparation method: the first step, the horse fat is ground, and the ground horse fat is heated to obtain liquid oil, that is, horse oil; the second step , after mixing horse oil and saponification agent at a mass ratio of 1:2 to 1:5, saponification reaction is carried out at a temperature of 50°C to 90°C for 0.5h to 3h to obtain a saponification liquid; the third step is to saponify Liquid and distilled water are mixed according to the mass ratio of 1:1 to 4:1 to obtain a mixed solution, and the mixed solution is extracted by adding n-hexane to the mixed solution according to the mass ratio of the mixed solution to n-hexane of 2:1 to 6:1. Obtain the n-hexane layer and the water layer, discard the n-hexane layer, adjust the pH of the water layer to 1 to 4 with mineral acid, and then add the water layer to the water layer according to the mass ratio of the water layer and n-hexane ...

Embodiment 2

[0016] Example 2, the oil rich in unsaturated fatty acids is obtained according to the following preparation method: the first step is to grind the horse fat, and heat the ground horse fat to obtain liquid oil, namely horse oil; the second step , after mixing horse oil and saponification agent at a mass ratio of 1:2 or 1:5, saponification reaction is carried out at a temperature of 50°C or 90°C for 0.5h or 3h to obtain a saponification liquid; the third step is to saponify Liquid and distilled water are mixed according to the mass ratio of 1:1 or 4:1 to obtain a mixed solution, and the mixed solution is extracted by adding n-hexane to the mixed solution according to the mass ratio of the mixed solution to n-hexane of 2:1 or 6:1. Obtain the n-hexane layer and the water layer, discard the n-hexane layer, adjust the pH of the water layer to 1 or 4 with mineral acid, and then add the water layer to the water layer at a ratio of 2:1 or 6:1 according to the mass ratio of the water ...

Embodiment 3

[0017] Embodiment 3, as a preference of the above-mentioned embodiment, in the first step, the horse fat is cleaned with distilled water, the fascia impurities are removed, dried and then minced; or / and, in the first step, the minced Horse fat is heated at a temperature of 50° C. to 80° C. to obtain liquid oil, namely horse oil.

Abstract

The invention relates to the technical field of unsaturated fattyacid extraction and provides grease rich in unsaturated fattyacid and a preparation method thereof. The grease rich in unsaturated fattyacid is prepared through the following steps: first step: grinding horse fat, heating the grinded horse fat, so that liquid grease namely horse oil is obtained; second step: after the horse oil and saponifier by mass ratio of (1 to 2) to (1 to 5) are mixed together, performing saponification for 0.5 h to 3 h at the temperature of 50 DEG C to 90 DEG C, so that saponification liquid is obtained. In the invention, according to different crystallization temperature of components in the horse oil, solvent crystallization is performed, the unsaturated fattyacid is obtained after further separation, the unsaturated fattyacid in the horse oil comprises oleic acid, linoleic acid, linolenic acid and palmitoleic acid. The method can be used for richly extracting monounsaturated fatty acid (oleic acid and palmitoleic acid) and polyunsaturated fatty acid (linoleic acid and linolenic acid), the method is simple and convenient, the operating temperature is low, and the yield is higher.

Description

technical field [0001] The invention relates to the technical field of unsaturated fatty acid extraction, and relates to an oil rich in unsaturated fatty acid and a preparation method thereof. Background technique [0002] All fatty acids containing carbon-carbon double bonds are called unsaturated fatty acids. Unsaturated fatty acids are divided into monounsaturated fatty acids and polyunsaturated fatty acids according to the number of double bonds. Fatty acids with one double bond are generally called monounsaturated fatty acids, and fatty acids with two or more double bonds are called polyunsaturated fatty acids. Oleic acid has a significant absorption-promoting effect on difficult-to-absorb antibacterial substances, anticancer agents and other medicines, and can be used as a pharmaceutical base or auxiliary agent with high stability and safety. Oleic acid can maintain the metabolism, excretion and circulation of cholesterol , to prevent arteriosclerosis; linoleic acid ...
