Na2EDTA is a heat resistant compound and can be easily binding minerals dissolved in the stomach and intestines. The objectives of this research was to assess changes in bioavailability of zinc (Zn) caused by the addition of Na2EDTA and fortified wheat flour processing. Bioavailability of zinc (Zn) was tested by using in vitro method that made a simulation of human digestion using pepsin and pancreatin-bile. Test results of bioavailability of zinc (Zn) showed that there were no significant differences (p> 0.05) in the bioavailability of zinc (Zn) on wheat flour processed by frying (donuts), steaming (Steamed Bun), or baking (bread). However, there was a tendency to increase the bioavailability of wheat flour processed by frying (donuts) and baking (bread) when compared to the raw dough. Raw dough had bioavailability of zinc (Zn) by 13.29%, after frying (donut) increase to 14.72%, and after baking (bread) increase to 17.06%. The addition of Na2EDTA also did not increase bioavailability of zinc (Zn) significantly (p> 0.05) for the three types of processing, despite increased bioavailability of zinc (Zn) on the donuts by 4.67%.
