Corn Processing Module
This module is designed to help understand how corn is processed into food, feed, and industrial products and where potential food and feed safety problems may occur, and how corn processing fits into feed manufacturing. This grain module is brought to you by the Iowa Grain Quality Initiative, and was produced by the Crop Advisor Institute.

Click here to access the Corn Processing Module



Learning objective: Identify types of corn processing, types of corn by-products used as feed ingredients, equipment used during corn processing, and any associated quality or feed safety concerns.

Introduction: Corn and corn by-products represent the largest single source of feed ingredients. Eighty percent of the United States corn crop is processed domestically into feed, food, or fuel. Each process has its own unique set of products and by-products, but all processors sell products into primary feed channels.

Corn by-products: Processing by-products - for example distillers grains, corn germ meal, corn gluten feed, and hominy feed — become ingredients in feed operations. Corn by-products that are used as livestock feed ingredients include dried distillers grains with solubles, syrup, and feed grade oil from the ethanol fermentation process. Other by-products that are commonly sold as feed ingredients are hominy feed from dry-milling and gluten meal and gluten feed from wet-milling.

Quality and feed safety: Physical hazards that could come in with grain during harvest are largely diminished by magnets and good management practices. Chemical hazards might be found in pesticide-treated seed that has been blended with field corn and delivered to the feed mill, or grain by-products might contain antibiotic residues from processing. Mycotoxins are also a significant hazard in grains and by-products. Feed ingredient quality is usually defined by USDA Grade factors or by contract specifications based on nutrient value.

Bacterial Leaf Streak of Corn
Bacterial leaf streak, caused by Xanthomonas vasicola pv. Vasculorum, was recently identified in Iowa. The disease has been found in field corn, seed corn, popcorn and sweet corn. Based on what we know about other bacterial diseases, the pathogen that causes bacterial leaf streak likely survives in corn residue and is spread by wind and rain/irrigation. The impacts on corn yield production are yet to be determined.

Nitrogen Use in Iowa Corn Production
Nitrogen is essential for growth and reproduction of crops and is involved in many important plant biochemical processes. Nitrogen management is critical for optimal yields for corn production systems. This publication discusses long-term research done in Iowa and shows corn yields average about 60 bu/acre for continuous corn and 115 bu/acre for corn following soybean when corn is not fertilized. However, corn fertilized with N will easily yield 200 bu/acre or more. This means soil management and nitrogen fertilization practices, such as using economical optimum N rates, should be used to help optimize crop yields, use N efficiently, and enhance water quality.

The regional Corn Nitrogen Rate Calculator website, which has been helping farmers determine profitable nitrogen rates since 2005, can be found at: cnrc.agron.iastate.edu. This tool provides a process to calculate economic return to N application with different nitrogen and corn prices and to find profitable N rates directly from recent N rate research data. Using the Maximum Return to Nitrogen concept within the calculator helps farmers implement the most economical nitrogen rate inputs, which helps moderate water quality issues.
