Therefore, nutritional factors such as a higher oil and protein contents were emphasized as was a softer kernel texture for improved energy utilization. In addition, corn good for wet milling uses typically has good carbohydrate energy utilization. In addition, indirect tests relating to kernel hardness were also used in the overall evaluation of dry milling quality. Wet Milling Assessment of the amount of starch yield from wet milling was determined using data obtained from laboratory wet milling. Cob color or grain color was not a factor in this ranking.
Some processors consider corn that is good for dry milling also good for alkaline processing.
Yellow Pigmentation Color, using the Hunter L, a, b color scale, using a Minolta photoelectric chromameter, was measured on both ground and unground samples. Yellow pigmentation can be both a positive or negative attribute depending upon the specific needs of the end-use processor. None of the samples tested in 1994 were positive for aflatoxin. Shipping Quality Shipping quality was assessed using the Wisconsin Breakage Tester. All of the samples tested had acceptable shipping quality.
