Abstract

The invention discloses a method for physically refining soybean crude oil and synchronously preparing soybean concentrated phospholipids employing enzymatic degumming. The method comprises the following steps: (1) taking soybean crude oil, and adding a citric acid to homogenize; (2) adding phospholipase and / or degummase to the homogenized soybean crude oil to homogenize; (3) stewing the crude oil homogenized in the step (2) for 1.5-3 hours, and then centrifugally separating, so as to obtain degummed oil and residues; (4) carrying out decolorizing, deodorizing and deacidifying on the degummed oil which is centrifugally separated in the step (3), so as to obtain product oil; (5) adding an organic solvent to remove neutral oil in the residues which are centrifugally separated in the step (3). By adopting enzymatic degumming, not only is a water resource saved, but also the produced product oil and residues are low in moisture, the quality of the phospholipids is easily controlled, and the product is stable in quality. Thus, the economic benefits are greatly improved.

Description

technical field [0001] The invention relates to the technical field of edible oil refining, in particular to a method for synchronously producing concentrated soybean phospholipids by enzymatically degumming and physically refining soybean crude oil. Background technique [0002] The existence of non-hydratable phospholipids in vegetable oils has brought a lot of trouble to oil refining. The traditional refining method is to degumming soybean crude oil with water. During the refining process, a large number of oil feet are produced. The soybean oil feet are disposed of as waste at a low price. Not only Cause environmental pollution, and, cause serious waste. At the same time, during the washing process, a large amount of sewage is produced, which must be treated by the sewage treatment station before being discharged up to the standard, which increases the economic burden of sewage treatment for enterprises. With the continuous expansion of the production scale of enterpris...
