LIPID FRACTIONATION AND PRODUCTS SO OBTAINED

摘要

There is described a process for extracting part of the lipids from a lipid or lipid containing mixture comprising contacting the lipid or mixture with a subcritical fluid at a suitable temperature and pressure and of a type such that part of the lipid is more soluble therein than the remainder of the lipid or other components of the mixture, under conditions so that a part of the lipid component is taken up by the fluid, and then recovering the lipid from that fluid, and optionally recovering the remainder of the lipid which is not taken up by the fluid. The process for example can be used to fractionate the triglycerides in butter or milk fat using subcritical carbon dioxide.
