Oil Fortification: Technology

The technology of fortification is simple and easily achievable by producers.3 As these are fat-soluble vitamins, they permit easy and cost-effective addition without the need for elaborate equipment and can be uniformly distributed in oil. Dosing technology for adding anti-oxidants and other micro ingredients to oil is routine. While for many oils, a temperature of 40-50 C is required to assure uniform mixing, the threshold to ensure uniform liquid state for oils like soybean oil is less than about 25 C. Producers generally report minimal adjustments to add vitamin A, D, E. Since other additives are often used, personnel and technology are already in place. The additional cost due to fortification is 7 paise per litre of oil with Vitamin A and D.
