High-amylose corn with starch containing 49 and 57% amylose can be wet-milled, with some modification in processing conditions, to produce a starch of slightly higher protein content, and in somewhat lesser yield, than is usually obtained from ordinary corn. A 64.4% yield of starch containing 0.51% protein was recovered from ordinary corn, as compared with a 43.5% yield of starch containing 0.7% protein from high-amylose corn (57%). An unusually large swelling of the corn kernels was observed during the steeping of high-amylose corn (57%). These kernels exhibited an increase of 128% of their original dry volume, as compared with a 63% increase in volume observed during the steeping of ordinary corn.
