Abstract

The invention relates to a process for recovering monoglycerides and optionally diglycerides and/or triglycerides as well as optionally glycerol from mixtures comprising glycerides and glycerol containing glycerides, respectively, by countercurrent extraction with a circulating extraction. As an extractant, forming a separate phase, there is used a hydrocarbon having a density of more than 180 kg/m.sup.3 and/or trifluoromethane having a density of more than 180 kg/m.sup.3.
