Abstract

The traditional method of measuring grain moisture, involving air oven drying, is time-consuming. Electric moisture meters are widely used in the rice industry but often require calibration using the air oven drying method. Therefore, an alternative, faster, and reliable approach is essential, especially for grain marketing. This study utilized rice samples of varying sizes: Bg 300 (medium fat), Bg 358 (short round), and At 405 (long thin). Five humidity levels (12-20% wet basis) were achieved by adding known water amounts. The correlation between moisture values in a microwave oven and hot-air oven was assessed using Pearson, Spearman, and Kendall coefficients. A linear regression relationship was established between the methods. The findings revealed a significant correlation (r > 0.55, P < 0.01) between the temperature values of the air furnace and the MW furnace for three rice samples, except at 870 watts. However, using 550 watts for 7 minutes showed a notably higher regression coefficient (r = 0.94, P < 0.01) for temperature values in the air furnace. In conclusion, household microwave ovens can effectively determine moisture content in various rice varieties, serving as an alternative to traditional air oven drying. This research aims to compare the efficacy of the two methods for moisture determination.
