Zusammenfassung:	PURPOSE:To recover carotene with excellent separation efficiency by simple operation, by passing carotene-containing natural fats and oils through a modified glass wool packing and carrying out treatment. CONSTITUTION:Carotene-containing natural fats and oils are subjected to alcoholysis with a lower monohydric alcohol to provide an oily phase, which is used and mixed with a hydrophilic solvent and water to deposit and separate carotene by heat exchange at 30-120 deg.C. The deposited mixture of a lower alkyl ester of a fatty acid with the hydrophilic solvent and water is then passed through a flocculating part filled with glass wool having the surface modified by coating with silicone films or silylation treatment. The deposited substance is subsequently separated from the residual liquid. Thereby a short residence time of the extract liquid in a separator is sufficient and separation efficiency can be improved by simple and compact operation.
