Title:
PRODUCTION OF FINELY DISPERSED CAROTENOID OR RETINOID SLURRY, THE CAROTENOID OR RETINOID SLURRY AND COLORING OF FOOD AND FEED
Document Type and Number:
Japanese Patent JP3884817
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To produce a finely dispersed and physiologically permissible carotenoid or retinoid slurry, having a long preservation stability and usable for coloring a food, in a mild condition by mixing a carotenoid or a retinoid with an aqueous medium in the presence of an emulsifier.
SOLUTION: A carotenoid or a retinoid is dissolved in a volatile and water miscible organic solvent at 50-250°C optionally under an elevated pressure within 10sec and thereafter the resultant solution is immediately mixed with an aqueous medium at 0-90°C in the absence of a protecting colloid and in the presence of at least one physiologically permissible emulsifier to form the objective finely dispersed carotenoid or retinoid slurry. Moreover, preferably, any of a lecithin, a mono-, di- or triglyceride, an (acetylated) polycarboxylic acid or an ascorbyl palmitate is used as the emulsifier and the carotenoid or retinoid forms into particles having <1μm particle diameter in the medium containing water in the objective slurry.
