摘要： Process for refining a triglyceride oil comprising bringing the oil into contact with at least an amount of aqueous alkali solution equal to the stoichiometric amount required to neutralize the oil, forming a soapstock and separating said soapstock and oil characterized by bringing the oil into contact with the aqueous alkali solution at a temperature in the range of from 40.degree. to 140.degree. C. and forming at a temperature in the range of from 40.degree. to 140.degree. C. a soapstock which contains with respect to the initial fatty acid content of the oil at least about 0.7 wt % of electrolyte and which comprises a member selected from the group comprising a single phase of neat soap, a binary phase mixture of neat soap and niger, a binary phase mixture of neat soap and lye and a ternary phase mixture of neat soap, lye and niger. Each of the niger, lye and neat soap phases is a single phase comprising water, electrolyte and soap. The lack of substantial amounts of free water reduces saponification and thus oil loss. The presence of niger and/lye can reduce the viscosity of the soapstock and hence aid its separation from the oil.
