    Abstract: Production of a stable vitamin emulsion or dry powder comprises forming an emulsion (A), in the presence of at least 1 protective colloid (C); and optionally (D) at least 1 sugar and/or sugar alcohol and/or other additives (E). When a powder is required, the emulsion is dried, optionally in the presence of a coating material. (A) is (A1)-(A4). (A1) contains vitamin K, vitamin D, vitamin E, and vitamin A or an inert oil, (or a mixture of vitamin A and an inert oil); (A2) contains vitamin K, vitamin D and vitamin A; and (A3) contains vitamin K, vitamin E, and vitamin A; and (A4) contains vitamin D, vitamin E, and vitamin A. The emulsions and powders may also be obtained by separately forming an emulsion of vitamin K and one of (B1), (B2) and (A4) (where both emulsions contain (C) and optionally (D) and (E)) in water, and mixing to give an emulsion (A). (B1) contains a mixture of vitamins A and D; and (B2) contains vitamin A and E. Emulsions containing vitamin D are obtained by dissolving vitamin D in an inert oil and/or vitamin A, and mixing with the other components; or mixing the other components, and mixing with vitamin D. Also claimed are the stable emulsions and powders, and foodstuffs, pharmaceuticals and animal feeds containing the emulsions or powders.
