FRACTIONATION OF TRIGLYCERIDE OILS

摘要

Process for triglyceride oil fractionation using a crystallisation modifying substance which is i) a copolymer having subunits A and B of which subunit A is derived from maleic acid or itaconic acid and subunit B is derived from vinyl alcohol alkyl substituted vinyl alcohol, acrylic acid or styrene, A and B being present in a ratio of 10:1 to 1:10, where 5-100 % of the maleic acid or itaconic acid subunits are connected to unbranched (C8-C24) alkyl chains and where 0-100 % of the vinyl alcohol or alkyl substituted vinyl alcohol or acrylic acid subunits are connected to unbranched (C1-C8)-alkyl chains and where ii) inulin or phlein of which 5-100 % of the hydroxyl groups on the fructose subunits are connected to (C8-C24) unbranched alkyl chains and 0-95 % of the hydroxyl groups have been esterified with a (C1-C8)-alkyl containing fatty acid, preferably acetic acid.
