HarvestPlus sets micronutrient target levels for biofortified crops by accounting for the physiological requirement of the micronutrient, the per capita consumption of each crop, nutrient losses (during storage, processing, or cooking), and the fractional absorption of the total micronutrient content. This data is used to estimate the percent of the estimated average requirement (EAR) for women and children provided by the total micronutrient content in biofortified crops.
