Effects of Oven Drying Temperature and Drying Time on Rough Rice Moisture Content Determination

ABSTRACT THE effects of oven drying temperature and drying time on whole-kernel, long-grain rough rice moisture content determination were investigated for different moisture content levels ranging from approximately 9 to 22% (w.b.). The results showed that a simplified oven method can be used for rapid moisture measurement with accuracy comparable to that of a standard Association of Official Analytical Chemists (AOAC) method. An equation was developed that relates the apparent moisture content determined using a given drying time and temperature to the moisture content determined by the standard AOAC method.
