Method for producing a carotenoid emulsion

The present invention is a suspension of the carotenoid is suspended in toluene, the carotenoid is heated to a temperature in the range of 50 to 120 ° C. by circulating in the range of retention time 10 to 600 seconds into the heated conduit lysed immediately is then the resulting solution, in the presence of an emulsifier, after being emulsified by mixing with the temperature of water in the range of 5 to 60 ° C., carotenoids emulsion, characterized in that toluene was distilled off under reduced pressure liquid process for the preparation of. The present invention, an emulsion having a carotenoid as an active ingredient, maintaining high total trans form ratio of the carotenoid, good productivity, conveniently, can be industrially advantageously produced.
