Effect of iron and folic acid fortification on in vitro bioavailability and starch hydrolysis in ready-to-eat parboiled rice.

Iron (Fe) and folic acid (FA) fortified parboiled rice was produced by applying 'brown rice parboiling' method. The effect of milling and the effectiveness of fortification were tested in relation to the amount of bioaccessible and bioavailable form of Fe and FA. An in vitro starch hydrolysis assay was employed to assess the effect on simulated glycaemic index (GI).
