Processing of mixtures containing lipids and proteins and products so produced

摘要

There is described a process for recovery of at least part of the proteins and/or non-lipid-solids from an aqueous liquid containing lipids and proteins comprising bringing a supercritical fluid at a suitable temperature and pressure and of a type such that at least part of the lipid is soluble therein, into contact with the liquid under conditions such that at least a part of the lipid component in the liquid is taken up by the fluid then recovering at least part of the protein and/or non-lipid solid from the residue. The process for example is useful in producing caseins, other proteins and lactose from the residue of milk after extracting the lipids with supercritical carbon dioxide.
