Abstract
About 18% of the corn produced in the United States is wet milled there. However, this corn can be detrimentallyaffected by artificial drying conditions that provide too much heat on corn that is very wet. Tests for 100g extractable starchwere performed on laboratorydried and commercial crossflowdried corn at different temperatures. Nearinfraredtransmittance calibrations were developed based on the 100g laboratory test for extractable starch. Each percentage pointgain in extractable starch is estimated to be worth a minimum of 4 to 6 cents per bushel. The NIT calibration may be usedas a rapid method for checking dried corn quality for extractable starch for wet milling.
