Abstract
Liquid oils with a SAFA-content of less than 5 wt % can be obtained by conversion of a fatty compound (A), preferably having a SAFA-level of more then 5 wt %, with a reactant (B), capable of forming different reaction products of the non-triglyceride type (C.sub.1, C.sub.2 etc.) having a different melting point and/or different solubility in compound (A); the SAFA-level of the end product can be controlled by separating the precipitate of the higher melting more saturated reaction-products (C.sub.1, C.sub.2 etc.) from the rest of the reaction mixture.

Process for the production of liquid oils with a SAFA-content below 5 wt. %, wherein a triglyceride fatty compound (A) comprising at least a saturated and an unsaturated fatty acid moiety, is converted by reaction with a reactant B comprising a polyhydroxy compound to form different non-triglyceride reaction products comprising diglycerides and mono-glycerides with different fatty acid composition (SU, SS and UU), which products have a different melting point and/or different solubility in compound A and decreasing the SAFA-level of liquid oil product by precipitating and removing the higher melting and/or less soluble non-triglyceride reaction products.
A process of producing liquid oils having a SAFA-content below 5 wt. % which comprises reacting, in the presence of an enzyme,
- (a) a triglyceride fatty compound (A) comprising at least a saturated and an unsaturated fatty acid moiety with
- (b) a polyhydroxy compound to form a liquid oil product containing non-triglyceride components comprising diglycerides and mono-glycerides with different fatty acid composition (SS, SU and UU) having different melting points and/or different solubility in the triglyceride,
- (c) reducing the SAFA content of the liquid oil product by precipitating and removing therefrom higher melting and/or less soluble non-triglycerides, and
- (d) enzymatically reacting the liquid oil product reduced in SAFA content obtained in (c) with an unsaturated fatty acid to decrease the SAFA content of the liquid oil product further.
