Abstract

The invention provides a method for extracting microbial oil. The method comprises the following steps: oil-producing microorganisms are inoculated and fermented; a fermentation liquor obtained after fermentation is further smashed and dried through a separating system, and dry biomasses with the water content not higher than 20 percent is obtained; after even mixing, physical wall breaking is performed on the dry biomasses and an organic solvent for extraction until the volume average diameter of thallus particles are smaller than 600 mum; an oil mixture is obtained through solid-liquid separation to a mixed solution after physical wall breaking; the microbial oil is obtained through desolvation to the oil mixture. According to the method for extracting microbial oil, provided by the invention, adding enzyme for wall breaking is not required, risks, caused by enzyme residue, on aspects of laws and regulations and food security, can be avoided, more deterioration reactions of oil under high temperature can be reduced greatly, and energy consumption is reduced.

Description

technical field

[0001] The invention relates to a method for extracting microbial oil. Background technique

[0002] Polyunsaturated fatty acid (PUFA) generally refers to a straight-chain fatty acid with two or more double bonds and a carbon chain length of 18-22. According to the position of the carbon atom where the double bond is located, it is generally divided into omega-3 series unsaturated fatty acids and omega-6 series unsaturated fatty acids. For example, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) belong to the omega-3 series, while linoleic acid and arachidonic acid (ARA) belong to the omega-6 series. Polyunsaturated fatty acids (PUFA) have many important physiological activities. It can regulate the normal metabolism of blood lipids and lipoproteins in the human body, reduce the content of cholesterol in the blood, and prevent cardiovascular and cerebrovascular diseases. At the same time, it can be converted into prostate glands in the body. The ...
