Claims
- 1. A process for preparing a fat fraction, suitable as fat component in non-lauric, non-hydrogenated, cool-melting, non-temper, non-trans filling or coating fats comprising fractionating in two steps, wherein both steps comprise wet fractionation, a triglyceride composition, containing at least 5 wt % SSU triglycerides wherein S=saturated fatty acid C.sub.16 -C.sub.22 and U=mono- or poly-unsaturated fatty acids C.sub.18 -C.sub.22, removing at least part of the trisaturated triglycerides, or at least part of di- and tri-unsaturated triglycerides or at least part of both, and isolating a triglyceride composition with an SSU content 12-20 wt %, which content is at least 1.7 times the SSU content of the starting triglyceride composition.
- 2. Process according to claim 1, wherein the SSU content of the starting triglyceride composition is at least 6 wt %.
- 3. Process according to claim 1, wherein the SUS content, S and U being identical with S and U of claim 1, of product isolated is at least 65 wt %.
- 4. Process according to claim 1, wherein the starting triglyceride composition is a stearin fraction obtained after dry fractionation of palm oil.
- 5. Process according to claim 4, wherein the palm oil stearin is fractionated in two steps.
- 6. A two-step fractionation process for the production of a fat fraction, suitable as a fat component in non-lauric, non-hydrogenated, cool-melting, non-temper, non-trans filling or coating fats which comprises the steps of
- (1) subjecting a feed triglyceride composition containing at least 5 wt % SSU triglycerides, wherein S=C.sub.16 -C.sub.22 saturated fatty acids and U=mono- or poly-unsaturated C.sub.18 -C.sub.22 fatty acids to wet fractionation with an organic solvent at -5.degree. to 50.degree. C. and separating a fraction consisting essentially of SSS, SUS and SSU triglycerides in a yield of 45-85 wt % based on the feed triglyceride composition, and
- (2) subjecting the fraction separated in step (1) to wet fractionation with an organic solvent at 15.degree.-25.degree. C. and recovering in a yield of 25-80 wt % based on the fraction separated in step (1), as the fat fraction, a product triglyceride composition having a SSU content of 12-20 wt %, which content is at least 1.7 times the SSU content of the feed triglyceride composition in step (1).
- 7. A process according to claim 6 wherein the feed triglyceride composition in step (1) is palm oil stearin, a stearin fraction is separated in step (1) and fractionated in step (2), and an olein fraction is recovered as the product triglyceride composition enriched in SSU.
- 8. A two-step fractionation process for the production of a fat fraction, suitable as a fat component in non-lauric, non-hydrogenated, cool-melting, non-temper, non-trans filling or coating fats which comprises the steps of
- (1) subjecting a feed triglyceride composition containing at least 5 wt % SSU triglycerides, wherein S=C.sub.16 -C.sub.22 saturated fatty acids and U=mono- or poly-unsaturated C.sub.18 -C.sub.22 fatty acids to wet fractionation with an organic solvent at 15.degree.-25.degree. C. and separating a fraction consisting essentially of U.sub.3, SUU, SSU and SUS triglycerides in a yield of 45-90 wt % based on the feed triglyceride composition, and
- (2) subjecting the fraction separated in step (1) to wet fractionation with an organic solvent at -5.degree. to 5.degree. C. and recovering in a yield of 25-80 wt % based on the fraction separated in step (1), as the fat fraction, a product triglyceride composition having a SSU content of 12-20 wt %, which content is at least 1.7 times the SSU content of the feed triglyceride composition in step (1).
- 9. A process according to claim 7 wherein the feed triglyceride composition in step (1) is a palm oil stearin, an olein fraction is separated in step (1) and fractionated in step (2), and a stearin fraction is recovered as the product triglyceride composition enriched in SSU.
- 10. Process according to claims 6 or 8, wherein the wet fractionations are carried out, using hexane, or petroleum ether or acetone as solvent in amounts of 1-8 l per kg triglyceride.
