Target Fortification Level (TFL)

  • Planning
  • Fortification


TFL is the average micronutrient concentration of a fortified food product measured at the factory. Food factories should aim to produce products that contain this target level. It is calculated by adding the natural intrinsic concentration of each micronutrient in the unfortified food vehicle to the FFL.
