Comparison of amylogram characteristics of milled rice between two instruments

This study was conducted to screen the effective method of amylogram analysis for the selection of high-quality rice variety. A comparison of amylogram characteristics was undertaken betwen Brabender visco analyzer (BVA) and Rapid visco analyzer (RVA). The screening efficiency of amylogram characteristics by RVA was nine times faster in analysis speed and 1/13 less in sample weight compared with BVA. Amylogram characteristics analysed by RVA such as peak viscosity, breakdown and setback viscosity were significantly correlated with those by BVA. Amylogram characteristics analysed by RVA were correlated with translucency and alkali spreading value in milled rice and hardness in cooked rice. RVA was more effecient than BVA to determine the amylogram characteristics for the selection of high-palatable rice.
