TWO-DIMENSIONAL FRACTIONATION OF MILK FAT

The invention relates to a process for preparing a fat fractionate, comprising providing an intermediate fat fraction of a starting material selected from the group consisting of milk fats and fat mixtures of milk fat and at least one other fat, which fat mixtures are composed of more than 50 wt. % milk fat, preferably at least 90 wt. % milk fat, said starting material preferably being anhydrous by a dry fractionation; and subjecting said intermediate fat fraction to a supercritical fluid fractionation, wherein the fat fractionate is obtained as a raffinate of the supercritical fluid fractionation or as a distillate of the supercritical fluid fractionation, optionally after removing the supercritical fluid. 本发明涉及制备脂肪分馏物的方法，包括：通过干式分馏提供选自乳脂及乳脂和至少一种其它脂肪的脂肪混合物的起始材料的中间脂肪馏分，所述脂肪混合物包含大于50重量％的乳脂，优选至少90重量％的乳脂-所述起始材料优选为无水的；和使所述中间脂肪馏分经受超临界流体分馏，其中脂肪分馏物作为超临界流体分馏的萃余物或作为超临界流体分馏的馏出物获得，任选地在除去超临界流体之后。
