2.4 Wide-angle X-ray Diffraction
Wide-angle X-ray diffraction (WAXD) analysis of the
used rice flours was performed using a nickel-filtered Cu
Ka radiation source (RINT RAPID-S; Rigaku-Denki Co.,
Ltd., Tokyo, Japan) generated at 40 kv and 30 mA. The rice
flour samples were scanned at room temperature through
the 2q region from 5º to 35º at a scanning rate of 1 º/ min.
The intensity distribution curves were measured using a
goniometer.
