Total mold counts on ambient-dried shelled corn remoistened to 23.6% moisture content were not affected by microwave heating temperatures of 42 and 51 C but were significantly reduced by microwave heating at 62 C. Total mold counts on freshly harvested shelled corn, although not affected by microwave heating temperatures of 55 C and lower, were significantly reduced by microwave heating at 57 C. In three lots of freshly harvested corn kernels (24.0-26.8% initial moisture content), internal molds were reduced from 100 to less than 20% by microwave heating at temperatures of 54-55 C. Germinability of these same lots of corn was significantly reduced at temperatures above 55 C and approached zero at 70 C.
