Overview

Fortification of flour and maize meal is a relatively straightforward process, used in many mills across the world. This website draws on this world-wide experience to provide up to date information and guidelines to facilitate the process for companies starting the process, or wishing to improve their operation. It draws on a number of publications, listed below, particularly the Fortification Handbook, prepared by the Micronutrient Initiative, and the WHO/FAO Guidelines to Fortification with Micronutrients.

The Table summarizes the distinguishing features of large, medium and small-scale milling. Mill size is determined by its production capacity, either in the amount of grain it can process or in the volume of product (flour, meal, bran, etc.) it can produce, both per unit time. Capacity is often larger than what a mill actually produces. Ideally, a mill should run over 90% of capacity but many mills in the world run at much less than that.

This website focuses on fortification methods used in large and medium-sized mills. Fortification in smaller mills requires adaptations to this approach. Click here for a comprehensive overview of Fortification in Small Mills.
