It is highly preferred that the degumming agent is phosphoric acid and/or citric acid.
It is further preferred that the time of the contact is 20-50min.
In order that idesia oil is better contacted with degumming agent, it is possible to use stirring rod is connect with degumming agent to idesia oil
The mixture for obtaining after touch is stirred.
According to the present invention, the weight ratio of idesia oil and water and the time of washing are had no particular limits, as long as energy
Enough fully washings.Preferably, the weight ratio of idesia oil and water is 1：1-2.
It is highly preferred that the time of the washing is 10-15min.
According to the present invention, in order to reach more preferable clean result, it is possible to use the relatively low water of hardness is washed.It is preferred that
Ground, in terms of calcium, the weight of magnesium ion, in the water, solubility calcium, the total content of magnesium salt are less than 100ppm (such as 20ppm, 50ppm
Or 80ppm etc.).Wherein, ppm represents hundred a ten thousandths.
According to the present invention, detached method is had no particular limits, if can by degumming after idesia oil with de-
Colloid and colloidal impurity are separated, and can be the various conventional separation methods in this area, such as standing separation or centrifugation.
Preferably, the detached method is centrifugation.
Hereinafter will be described the present invention by embodiment.
In following examples, the main component in the colloidal impurity contained due to idesia oil is phospholipid, therefore with phospholipid
The degumming effect reduced to judge the inventive method of content, in raw material idesia oil, the content of phospholipid is 0.11 weight %；Make
In water, solubility calcium, the total content of magnesium salt are 60ppm；The method reference of content of phospholipid in idesia oil after measurement degumming
