Claims20
A process for preparing a stable vitamin emulsion or a stable vitamin dry powder which comprises emulsifying in each case separately in water:
- a) vitamin K and
- b) a mixture of vitamin D, vitamin E and vitamin A or an inert oil or a mixture of vitamin A and an inert oil, obtainable by
- b1) dissolving vitamin D in an inert oil and/or vitamin A, and mixing with vitamin E, or
- b2) adding vitamin D to a mixture of vitamin E and vitamin A and/or an inert oil,
- carrying out the emulsification of components a) and b) in each case in the presence
- c) of one or more protective colloids,
- d) where appropriate of one or more sugars and/or sugar alcohols and
- e) where appropriate other additives,
- subsequently mixing the emulsions and drying the mixture to prepare a stable vitamin dry powder, where appropriate in the presence of a coating material.
