Abstract: Disclosed are methods that permit the determination of both lipid moiety (LM) and apolipoprotein expressed epitope immunoreactivity (EEI) of intact isolated lipoprotein species. One format of the method isolates a lipoprotein species by means of a ligand binding to a solid phase, and quantitates thereafter the LM and/or the EEI. A complementary variant format provides for nonquantitative study of a constant number of lipoprotein particles exploring the sizes of the particles (LM) and scanning the apolipoprotein epitopes (EEI). Disclosed also is a method using lipid moiety dynamics (LMD) and expressed epitopes immunoreactivity dynamics (EEID) to explore the lipid loading and unloading of the lipoprotein species during a fast-feeding cycle. Both the LMD and EEID of lipoprotein particles may be performed as a panel, individual or in any combination. This can be used to detect abnormalities in lipid metabolism that precede the hyperlipidemias associated with cardiovascular disease.

Abstract: The process for recovering vegetable oleaginous substances from oil-containing natural substances comprises a series of continuous combined pressing and extraction steps to increase and simultaneously to guarantee a high quality product for different kinds of natural substance starting materials. This is accomplished by subjecting the natural substances, conditioned and comminuted if necessary, after mixing with a solvent phase containing some oil to an intensive processing, mixing and extraction in the shear field of at least one rotor-stator unit and subsequently feeding the resulting liquid phase, through a filter if necessary, to a distillation column. The solid phase is extracted in successive stages until a residual oil content of 1% is reached and the solvent is fed back to a solid phase in a counterflow. The process as defined in my invention is universally applicable to all fat and oil-containing natural substances using suitable fluid extraction means.
