Claims
- 1. Process for the production of liquid oils with a SAFA-content below 5 wt. %, which comprises reacting a triglyceride fatty compound (A) comprising at least a saturated and an unsaturated fatty acid moiety, 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, the reactant B being selected from the group consisting of polyhydroxy compounds, long chain fatty alcohols (6-22 C-atoms); long chain unsaturated fatty acids or their esters and basic salts of inorganic cations and the reaction being performed by applying an enzyme.
- 2. Process according to claim 1, wherein the fatty component (A) is selected from the group consisting of: sunflower oil, high oleic sunflower oil, safflower oil, high oleic safflower oil, corn oil, cottonseed oil, rapeseed oil and soybean oil.
- 3. Process according to claim 1, wherein the the product oil has a SAFA content of less than 3 wt %.
- 4. Process according to claim 1, wherein the reaction product obtained is subjected to a molecular distillation or to a fractionation, for the removal of at least part of the reaction products.
- 5. Process according to claim 1, wherein the process is applied for the preparation of a liquid oil that displays:
- (1) a SAFA-content <5 wt %,
- (2) a weight ratio ##EQU3## (3) a C.sub.18:2 content of >25 wt %, (4) a C.sub.18:3 content of 0-20 wt %
- (5) a diglyceride content of 15-70 wt %.
- 6. 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.
- 7. A process according to claim 6 wherein the polyhydroxy compound is glycerol.
- 8. A process according to claim 6 wherein the triglyceride fatty compound (A) has a SAFA-content of more than 5 wt. %.
- 9. Process for the production of liquid oils with a SAFA-content below 5 wt. %, which comprises reacting a triglyceride fatty compound (A) comprising at least a saturated and an unsaturated fatty acid moiety, 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, the product thus obtained being reacted with unsaturated fatty acids enzymatically in order to reduce the SAFA-content of the product further.
