    摘要: 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.-carotene deficiency.

    摘要: A process for the continusous preparation of Beta-carotene together with an emulsifier by briefly heating Beta-carotene together with an emulsifier to give a homogeneous solution, rapidly cooling the latter to below 100.degree. C. by adding water, and subsequently adjusting to the required final concentration of Beta-carotene, comprises pumping a suspension, which has been preheated from 20.degree. to 80.degree. C., of 1 to 40% by weight of Beta-carotene in an emulsifier through a heating coil located in a heat transfer oil, where the solubilization mixture is at from 120.degree. to 180.degree. C. and the residence time is from 10 to 300 seconds, and subjecting the homogenous solution to turbulent mixing in a mixing chamber with an amount of water at from 10.degree. to 80.degree. C. to result in a solubilizate which contains from 0.5 to 6% by weight of Beta-carotene and is, if necessary, diluted to the required final concentration.
