An apparatus for separating a mixture of two liquids of different densities which liquids are substantially insoluble in one another includes a hollow permeable body having a recess for receiving a first fluid which can flow from the recess through the permeable body to an exterior of the permeable body. A housing surrounds and is spaced from the exterior of the permeable body. The housing has an inlet for a second fluid and an outlet for a mixture of the first and second fluid. A baffle or baffles are provided in the space between the exterior of the permeable body and the housing, and to define a mixing channel in space between the exterior of the permeable body and the housing so that the second fluid can enter the housing inlet and flow through the mixing channel to the outlet, while picking up fluid on the exterior of the permeable body.

A semi-aqueous method for extracting a substance. The method involves combining a first liquid or solid substance containing an extract with a semi-aqueous solution containing a water-soluble or water-emulsifiable (WSWE) compound. Said WSWE compound selectively dissolves extract during a dense phase CO.sub.2 expansion and salting-out process, which is simultaneously co-extracted using said dense phase CO.sub.2, and desolvated to produce a CO.sub.2 salted-out solvent mixture containing extract. Said CO.sub.2 salted-out solvent mixture is treated using various secondary processes. The present invention is useful for producing extracts for use as additives in pharmaceuticals, nutraceuticals, cosmetics, beverages, or foods, and for quantitative analysis.
