Abstract
Whole-kernel processed sweet corn has to be harvested at a precise stage of maturity. In general, when the moisture content of the kernels is 74% ± 1%, the ears are ready for harvesting and rapid processing. Several methods of determining sweet corn maturity were evaluated to determine their suitability for use in the processing industry. The refractive index of the kernel juice was an accurate, simple, and rapid method of determining maturity, and was considered superior to all other methods studied. Moisture content, alcohol-insoluble solids content, and trimetric rating were adequate indices of maturity, but were too time-consuming. Pericarp content was neither reliable nor rapid. Shear-press ratings did not give accurate or consistent results.
