  • Stable vitamin and/or carotenoid products in powder form, and the preparation thereof
    Patent number: 5356636
    Abstract: A process for preparing stable dry powders which are insoluble in hot water and which contain fat-soluble vitamins and/or carotenoids, which comprises the following steps:a) preparing an aqueous dispersion containing essentially these fat-soluble active substances, film-forming colloids and reducing sugars,b) converting this dispersion into dry vitamin and/or carotenoid products in powder form andc) thermally curing the powder at from 60.degree. to 180.degree. C.,wherein gelatin in combination with one or more organic amino compounds which are free or bonded in the manner of a salt and which contain a basic primary amino group and, in addition, either another amino group, a hydroxyl group, an alkoxy group or a carboxyl group, and/or in combination with sufficient basic alkali metal or alkaline earth metal compound for the dispersion to have a pH of from 7.5 to 10, is used as film-forming colloid, and the dry powders obtainable via this process are described.

  • Pulverulent products composed of a water-insoluble core substance and of a protective covering
    Patent number: 5290567
    Abstract: Pulverulent products composed of a water-insoluble core substance and of a protective covering, are obtainable bydispersing the core substance in an aqueous solution of amylose or a starch with an amylose content of more than 40% by weight as film-forming polymer for the protective covering,spraying this dispersion using hydrophobic silica as auxiliary andsubsequently drying the sprayed particles.

  • Stable injectable .beta.-carotene micellar solutions and their preparation
    Patent number: 4435427
    Abstract: A process for the preparation of .beta.-carotene micellar solutions, wherein a non-ionic emulsifier which is suitable for the preparation of micellar solutions is heated at from 160.degree. to 180.degree. C. and a total of from 20 to 30% by weight, based on the emulsifier, of .beta.-carotene is introduced in the presence of a conventional antioxidant, the hot homogeneous mixture is cooled rapidly to below 100.degree. C. by adding water, and the formulation is brought to the desired concentration of from 3 to 6% by weight by adding further water, and the .beta.-carotene micellar solutions obtained by this process. The non-ionic emulsifiers used in this process have an HLB value of from 12 to 16, and are in particular oxyethylated triglycerides of fatty acids of 12 to 18 carbon atoms containing 20-60 oxyethylene units. Parenteral admininstration of the stable .beta.-carotene micellar solutions according to the invention to cattle relieves the disturbed estrus cycle and impaired fertility caused by .beta.
