    Abstract: PROBLEM TO BE SOLVED: To eliminate the generation of aggregation, precipitation, and diffusion and to produce stable fine particles efficiently by dissolving two kinds of substances in different compressible supercritical fluids, making the substances penetrate into each other in conditions in which the dissolution limit of one substance exceeds earlier than that of the other substance. SOLUTION: When substances A, B are dissolved in a supercritical fluid, and the pressure of the solution is reduced along a pressure holding section to produce stable fine particles, the substances A, B are dissolved in different compressible supercritical fluids. In conditions in which the dissolution limit of the substance A exceeds earlier than that of the substance B, the substances are made to penetrate into each other. For example, fluids are passed from both supply lines 1, 5 through both high pressure autoclaves 2, 6, where the substances A, B are taken out. Both supply lines 3, 7 are connected to both pressure reducing apparatuses 4, 8, and the mixing of the fluids before pressure reduction is prevented. Moreover, the particles 10 of the substance A are coated with the substance B.

    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 deg.C optionally under an elevated pressure within 10sec and thereafter the resultant solution is immediately mixed with an aqueous medium at 0-90 deg.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
