Iron (Fe) content
The iron contents in rice were determined
using atomic absorption spectrophotometer-AAS
(100 Analyzer, Perkin Elmer, Germany). The iron
detection limit of AAS used in this study was 0.039
mg/kg. Dehusked rice flour samples (2–4 g) were
wet-acid digested with nitric acid and solubilized
with 10 mL
