Yield, protein content, and viscosity of starch from wet-milled corn hybrids as influenced by environmentally induced changes in test weight

Forty-three yellow dent corn samples of five different hybrids varying in t est weight and moisture content were obtained from 14 different locations i n 1993. The locations for acquired samples were selected randomly to cover a wide range of test weights based on preliminary data from eight states of the corn belt where 94% of the U.S. corn crop was produced in 1993. Sample s were wet-milled using a 100-g standard laboratory-scale wet-milling proce dure. Protein content in starch and starch viscosity were determined. Starc h yield, protein content in starch, and starch viscosity were not affected significantly by test weight.
