A justification for using a whole-grain oven method to determine soybean moisture content

Three air-oven moisture methods, AOCS Ac 2-41, AACC 44-18 and the official USDA method, were compared on 20 samples of 1987 crop soybeans. The AOCS method is a whole-grain method, the other two are two-stage, ground-grain methods. The average difference between the AOCS and USDA methods was 0.04 percentage points with a standard deviation of 0.18 points. The AOCS method can be used interchangeably with the USDA method for calibration of moisture devices. The AACC method averaged 0.15 and 0.19 points higher than the AOCS and USDA methods, respectively.
