Abstract
The invention concerns a fractionation process for the production of triglycerides with at least 12 wt % SSU (S=saturated fatty acids; U=unsaturated fatty acids) by subjecting a fat with at least 5 wt % SSU to a fractionation, achieving an enrichment factor fo the SSU enrichment of at least 1.5

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.
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).
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).
