The possibility of using a micro-wave oven as a rapid method for moisture determination of corn grain was verified, as well as the effects of different potencies on the moisture content of the grains. In this study corn samples with moisture contents in the range of 7,33 to 22,28% were used. Linear regression lines were determined by the relation of the values of percentage of water taken out after drying in the microwave and the moisture contents determinated by the oven official method (105°± 3°C/24 hours). The drying time of the product was fixed at 45seconds. In the conditions of this experiment, the microwave oven has shown to be a feasible alternative for a rapid determination of the corn moisture content.
