Cooking oil is plant, animal, or synthetic fat used in cooking and food preparation and is therefore more accurately termed edible oil. Edible oil is very suitable food for fortification with vitamin A since it is in widespread private and commercial use. BASF is a leading vitamin A producer offering special products for the fortification of vegetable oil, ghee, vanaspati, margarine and spread.
The fortification process requires only few special equipment, as vitamin A itself is an oil in its natural state and is readily miscible with other oils and fats. Blends with other oil-soluble vitamins like vitamin D and vitamin E are available on request.
Edible oil fortification is generally considered safe. No incidents of intoxication have been reported so far. However, vitamin A in its pure form as nutritional ingredient is only suitable for food production, never for direct consumption. Properly applied to high-calorie dense foods such as oil, even high edible oil consumption will keep consumers within the safety limits. Nevertheless, accurate dosage and application must be subject to continuous or batch-wise quality assurance among producers and by regulatory authorities.
BASF developed a calculator for the amount of vitamin A needed to fortify a given amount of vegetable oil to meet a specific fortification level
