Abstract

The invention provides a method for preparing powdered soybean phospholipids. The method comprises the following steps: extracting hydrated oil sediments with acetone as a solvent; separating out an insoluble substance of the acetone; and drying the insoluble substance of acetone under low temperature in vacuum. The invention also discloses the powdered soybean phospholipids prepared by the method. The powdered soybean phospholipids have color mush slighter than that of the existing powdered soybean phospholipids, and the peroxide value is less than that of the existing soybean phospholipids.

Description

technical field [0001] The invention belongs to the field of oil processing, and relates to a method for preparing powdered soybean lecithin, in particular to a method for preparing powdered soybean lecithin by using acetone as a solvent. Background technique [0002] Phospholipids are yellow or brown phosphorus-containing lipids that are insoluble in acetone. "Hydrated phospholipid" refers to the yellow thick substance obtained after vegetable crude oil is hydrated and separated during filtration. Hydrated phospholipids are also called "hydrated oil feet" or oil feet in the oil processing industry, and their main components are water, triglycerides and phospholipids. [0003] From the analysis of chemical structure, phospholipids mainly include phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and phosphatidic acid. At present, the general phospholipid production process at home and abroad is to first remove the water from the "hydration oil foot" or oil...
