Pasting properties were investigated using the Rapid Visco-Analyser (RVA-4D, Newport Scientific Pvt Ltd., Australia) following the approved method 61.02 (AACC, 2008). A 13-min RVA profile was used with 3.0 g ground samples (adjusted to 14% moisture content) in 25mL distilled water. The RVA Thermocline software(ver. 2.6) was used to obtain the pasting temperature, peak, trough,and final viscosities of the samples. Each sample was analysed in duplicate.
