Bioaccessibility and total content of iron, zinc, copper, and manganese in rice varieties (Oryza sativa L.) : A probabilistic assessment to evaluate their contribution to dietary reference intake

Background and objectives: Fe, Zn, Cu, and Mn contents as well as bioaccessi- ble fractions of eight rice varieties were analyzed in order to evaluate them nutri- tionally. Findings: Total trace element concentrations ranged between 5.90 and 15.3 mg/ kg for Fe, 8.82–12.9 mg/kg for Zn, 1.45–5.5...

Findings: Total trace element concentrations ranged between 5.90 and 15.3 mg/ kg for Fe, 8.82–12.9 mg/kg for Zn, 1.45–5.59 mg/kg for Cu, and 2.45–13.6 mg/ kg for Mn.
