Abstract: The invention relates to a process for splitting soapstock, comprising the steps of mixing the soapstock with a soap splitting acid, and of separating the acid water phase formed from the oil phase, characterized in that the mixture of the soapstock and the soap splitting agent are subjected to a high temperature treatment at or above 100.degree. C. during a residence time equal to or more than 2 minutes.

Abstract: The invention relates to a method for refining virgin olive oil, in which the virgin olive oil is filtrated, characterized in that the virgin olive oil is micro-filtrated.

Abstract: The invention relates to a method for dewaxing oil, comprising steps of:i) drying the oil to a water content of less than 0.5% by wt;ii) heating the oil to a temperature at which the oil does not contain nucleation seeds for wax crystal formation;iii) cooling the dried oil from the temperature at which it does not contain nucleation seeds for wax crystal formation, at a cooling rate of less than 15.degree. C. per hour and at a temperature difference between the oil and the coolant medium of less than 15.degree. C., to an oil end temperature being in the range of 2.degree.-10.degree. C. wherein a solid wax is formed; andiv) removing the solid wax by microfiltration.
