Problems solved by technology

At present, there is no report on the application of fatty acids in animal feeding. This is because in the conventional fatty acid extraction process, especially the fatty acid extraction from animal product waste: dairy product waste residue, mouse feces, etc. are mostly extracted from saturated fatty acids. , the content of unsaturated fatty acids is less, but animals have a certain ability to synthesize saturated fatty acids, and the demand for unsaturated fatty acids is greater. Therefore, if the fatty acids extracted from animal product wastes are to be used in feed additives, It is necessary to increase the content of unsaturated fatty acids, especially the essential unsaturated fatty acids that cannot be synthesized by animals - linoleic acid, etc.; and in order to effectively extract the unsaturated fatty acids in animal product waste, how to improve the extraction yield of fatty acids Technical problems to be solved by those skilled in the art

Embodiment 1

[0021] The present embodiment provides a kind of fatty acid extraction method, and this method comprises the steps:

[0022] (1) parts by weight are: 25 parts of peanuts, 12 parts of camellia oleifera residue, 21 parts of wintersweet seeds, 9 parts of mouse excrement, 9 parts of dairy waste water scum and 9 parts of milk are pretreated respectively, and then Mix to obtain the extract;

[0023] (2) Mix the extract from step (1) with ethanol with a volume percentage of 75% (v / v) at a mass ratio of 1:1, then put it into a freezer at -20°C for 30 minutes, and take it out Afterwards, put it directly into a constant temperature water bath with a temperature of 90°C to thaw and heat it. When the temperature of the mixture reaches the temperature of the water bath, continue heating in the water bath for 10 minutes; after the water bath is heated, put the mixture into an ultrasonic extractor for ultrasonic extraction. The ultrasonic power density is 400w / L; the ultrasonic treatment te...

Embodiment 2

[0031] The present embodiment provides a kind of fatty acid extraction method, and this method comprises the steps:

[0032] (1) parts by weight are: 46 parts of peanuts, 34 parts of camellia oleifera residue, 34 parts of wintersweet seeds, 23 parts of mouse excrement, 17 parts of dairy waste water scum and 15 parts of milk are pretreated respectively, and then Mix to obtain the extract;

[0033] (2) Mix the extract from step (1) with ethanol with a volume percentage of 90% (v / v) at a mass ratio of 1:1, then put it into a freezer at -15°C for 50 minutes, and take it out Afterwards, put it directly into a constant temperature water bath with a temperature of 100°C to thaw and heat it. When the temperature of the mixture reaches the temperature of the water bath, continue heating in the water bath for 15 minutes; after heating in the water bath, put the mixture into an ultrasonic extractor for ultrasonic extraction. The ultrasonic power density is 700w / L; the ultrasonic treatme...

Abstract

The invention relates to the technical field of fatty acid processing, in particular to a fatty acid extraction method. Extraction raw materials of fatty acid comprise peanuts, camellia oleifera residues, wintersweet seeds, mouse excrement, dairy product wastewater scum and milk, wherein the components contain fatty acid components to different degrees, the camellia oleifera residues, the wintersweet seeds, the mouse excrement and the dairy product wastewater scum are all waste, the waste can be effectively recycled according to the proportion of the raw materials, and the peanuts, the camellia oleifera residues, the mouse excrement, the dairy product wastewater scum and the milk are preprocessed in the extraction process so that the separation rate of fatty acid can be effectively increased. Meanwhile, the content of unsaturated fatty acid in fatty acid can also be increased.

Description

【Technical field】 [0001] The invention relates to the technical field of fatty acid processing, in particular to a fatty acid extraction method. 【Background technique】 [0002] Fatty acid (fatty acid) refers to a long aliphatic hydrocarbon chain containing a carboxyl group at one end. It is an organic substance. The general formula of a straight-chain saturated fatty acid is C(n)H(2n+1)COOH, and the lower fatty acid is colorless. Liquid, with a pungent smell, the higher fatty acid is a waxy solid, no obvious smell. Fatty acids are the simplest type of lipids and are the building blocks of many more complex lipids. Fatty acids can be oxidized and decomposed into CO in the presence of sufficient oxygen supply 2 and H 2 O, release a lot of energy, so fatty acid is one of the main energy sources of the body. [0003] Fatty acids are mainly used in the manufacture of daily cosmetics, detergents, industrial fatty acid salts, paints, paints, rubber, soaps, etc. At present, the...
