PROCESS FOR EXTRACTING NATIVE PRODUCTS WHICH ARE NOT WATER-SOLUBLE FROM NATIVE SUBSTANCE MIXTURES BY MEANS OF CENTRIFUGAL FORCE

摘要

The extraction of native products is rendered difficult by the fact thatattraction forces act between the liquid native products which arenot water-soluble and the tissue incorporating them, and that otherconstituents are dissolved or present in the form of particles in suspensionin the products during the extraction process. The initial substance mixtureis, therefore, processed together with a water-soluble, organicsolvent and optionally water to form a paste. The addition of the water-soluble, organic solvent enables the substance mixture to beseparated cleanly into an aqueous phase and an organic phase in thecentrifugal field, no further cleaning being necessary for the organicphase. The process according to the invention has a wide area of application.In principle, it can be applied to all substance mixturescontaining liquid, organic substances, in particular to vegetable and animaltissue. It is suitable for extracting oils from oleaginous fruit orwaxes from wax-containing plants, as well as for extracting fish oils.
