Beschreibung
Zusammenfassung:	PURPOSE:To obtain precipitated carotene, by alcoholyzing natural oil and fat with a lower monohydric alcohol to obtain an oil phase containing carotene and composed mainly of a fatty acid lower alkyl ester, adding a hydrophilic solvent and water to the oil phase and passing the mixing through a fibrous filler. CONSTITUTION:Natural oil and fat containing carotene are alcoholyzed with a lower monohydric alcohol to obtain an oil phase containing carotene and composed mainly of a fatty acid lower alkyl ester. The oil phase is added with a hydrophilic solvent and water and heated at 30-120 deg.C to convert carotene to concentrated small oil droplet phase having a diameter of 1-10mum. The phase containing oil droplet is passed through a coagulation zone filled with fibrous material to obtain carotene droplet grown to a diameter of about 5-10mm. The fibrous material is composed of a material wettable with a fatty acid lower monoalkyl ester (e.g. PVC, nylon, polyester or glass wool) and the packed density of the fibrous material is 0.05-0.3g/cm . The above process can be performed without using a large-sized separation apparatus.
