Micronutrients: selection and suitability
It is important to stress that the selection of
micronutrients depends not only on their legal status,
price, expected bioavailability, stability, and sensory
acceptability but also on the product forms
fitting the applied fortification technology. In some
applications, water-soluble forms might be suitable,
and in others water insoluble or even oily forms
might be preferred.

Zinc deficiency is often an important public health
issue. As in flour fortification, zinc oxide in rice fortification
is doubtless the product formof choice unless
a highly water-soluble product form is needed.
Zinc oxide does not cause taste issues, has a good
bioavailability, is cheap, and has no effect on color.
