PCT No. PCT/FR94/00301 Sec. 371 Date Oct. 25, 1995 Sec. 102(e) Date Oct. 25, 1995 PCT Filed Mar. 18, 1994 PCT Pub. No. WO94/21764 PCT Pub. Date Sep. 29, 1994A process for preparation of a fat fraction of vegetable origin enriched with unsaponifiable materials. A fat of vegetable origin is treated with a hot polar solvent of the ketone type to obtain a first fraction insoluble in the hot ketone solvent which is rich in unsaponifiable materials, and a second fraction which is a solution of hot soluble materials. The first fraction is then separated from the second fraction, and the second fraction is subjected to a crystallization in a crystallization solvent at a temperature below 0 DEG C., followed by filtering to obtain a filtrate. The crystallization solvent is then evaporated from the filtrate to obtain a further fraction rich and unsaponifiable materials. |
