  • Patent number: 9238009
    Abstract: A method for preparing fat-soluble active ingredients, including the steps of preparing an oil-in-water emulsion including 8 to 20% of at least one protein, 5 to 15% of at least one sugar, 0.5 to 3% of at least one inorganic salt, 10 to 22% of at least one fat-soluble active ingredient in an oily form and/or dissolved in an edible oil, and qsp % of water, shaping of particles in a substantially spherical shape by the dispersing the oil-in-water emulsion obtained at the end of step a) in a fluid, adding at least one agent for cross-linking of the at least one protein to the dispersion obtained at the end of step b), and the active ingredients are recovered with the substantially spherical shape.

  • Patent number: 8652547
    Abstract: The present invention relates to a process for preparing cores of granules intended for animal nutrition, the said cores comprising: a hydrophilic active principle present in an active content of greater than or equal to 60% by weight, at least one meltable binder, at least one plasticizer, the said process comprising (a) a first step of mixing of the ingredients, (b) a second step of extrusion of the mixture through an extruder, especially a single-screw or twin-screw extruder, equipped with one or more dies, so as to obtain rods, and (c) a third step of spheronization of the rods, the said process being characterized in that a preliminary dry co-grinding of the ingredients is performed before extruding the mixture, the said co-grinding being performed at a temperature of not more than 50° C. The present invention also relates to a process for preparing granules of hydrophilic active principle comprising the said cores.

  • Publication number: 20060051479
    Abstract: The homogeneous solid granules of the invention comprise at least 5% (w/w) of carotenoid, gelatine and a sugar, they have a size distribution of from 100 ?m to 2000 gm and are solvent-free. The process for producing such granules comprises the following steps: (a) preparing an aqueous solution of at least gelatine and a sugar, (b) adding at least said carotenoid in said aqueous solution, (c) adding the preparation obtained in (b) to an oil to obtain an emulsion of granules, (d) cooling said emulsion to solidify the granules, and (e) recovering and drying the granules.

  • Patent number: 5500415
    Abstract: A process for the preparation of spherules and emulsions containing such spherules. A primary oil-in-water emulsion is formed containing particles comprising one or more active principles in oily form suspended in water, the water optionally containing at least one protein. Controlled division of the primary emulsion is achieved by combining the primary emulsion with a water-immiscible solvent to create a second emulsion containing spherules of the primary emulsion. Preferably, the particles of the primary emulsion have mean diameters of about 1 .mu.m, and preferably, the spherules contained in the second emulsion have a diameter ranging from 100 .mu.m to 500 .mu.m. If protein is contained in the primary emulsion, the protein can be cross-linked. Further, the spherules can be separated from the water-immiscible solvent.
