METHOD FOR PRODUCING CAROTENOID EMULSION

Japanese Patent JP2002302479

A

To provide a method for simply, industrially and advantageously producing an emulsion containing a carotenoid as an active ingredient with good productivity by keeping a total high trans-isomer ratio of the carotenoid.

This method for producing the carotenoid emulsion is characterized by making a suspension containing the carotenoid suspended in a high- boiling organic liquid flow through a conduit heated at a temperature within the range of 120-700°C and having 0.1-50 mm inside diameter at a residence time within the range of 0.05-5 s, thereby heating the suspension, dissolving the carotenoid, then directly adding the resultant solution into an aqueous solution containing an emulsifying agent and emulsifying the carotenoid.
