X-ray diffraction (XRD) patterns of the F. thunbergii flours were analyzed using Rigaku D/max 2500 X-ray powder diffraction(Rigaku, Tokyo, Japan) with nickel-filtered Cu K radiation( = 1.54056˚A) running at 40 kV and 200 mA. The scattered radiation was detected in the angular range of 4–45◦2, with as canning speed of 5◦(2)/min and a step size of 0.06◦2. The degreewas weighed.
