Flour, a widely consumed staple food in many cultures, is a good source of dietary fiber, and is also an excellent source of other essential nutrients including magnesium, zinc and selenium. Fortifying flour with essential vitamins and minerals is a commonly used and cost-effective method to ensure a sufficient supply of micronutrients. It is prudent to consider other vitamins and minerals in addition to adding vitamin A as part of the overall flour fortification program.
Vitamin A for flour fortification is in powder form and has been specially developed for the purpose of fortification. It possesses the unique characteristics like high stability during storage and the final products, high purity, easy application, excellent flowability and low dusting.
The principle of flour fortification is to blend some amount of flour/carrier with vitamin and mineral premix before mixing it with the remaining flour in a continuous mixer.
