Gelatine for vitamin coatings.
Gelatine plays a special role in the formulation of stable and administration-friendly forms of vitamins based on oil (A + E) for humans and for animal fodder. Finely distributed vitamin A or E drops in an aqueous gelatine solution can be converted to a free-flowing powder using a special setting and drying process. The powder then remains easily dispersible in aqueous solution. In addition, by providing the vitamins with a coating of special gelatine, they remain stable and are protected from the effects of light and atmospheric oxygen. The coating is also soluble in hot and cold water. Effervescent vitamin tablets are a good example.
