2012 Corn Harvest Smaller, But Test Weight and Protein Up

 
Despite a drought-stressed dent in yields and production and reports of higher levels of mycotoxins, the overall quality of the 2012 U.S. corn crop was high, according to the U.S. Grains Council’s Corn Harvest Quality Report 2012/13. This year’s crop showed a year-over-year improvement in average text weight, protein levels and density, as well as lower moisture and broken corn and foreign material (BCFM) than the 2011 crop.
Tests conducted on corn samples in 12 states revealed:
• average test weight for the 2012/13 crop was 58.8 lbs./bushel.
• protein content averaged 9.4%, up from 8.7% in 2011.
• starch content averaged 73.0% in 2012, close to the 73.4% found in 2011.
• 78.0% of samples had no detectable levels of aflatoxins (above 2.5 parts per billion, or ppb, down from 97.9% in 2011; 14.1% of the samples tested above the FDA action level of 20 ppb.
• 94.9% of samples, had no detectable levels of DON (less than the 0.2 parts per million, or ppm); 100% tested below or equal to the FDA advisory level of 5 ppm.
The report assess the quality of the U.S. crop as it is delivered from farms to local elevators, the first step in entering international marketing channels. Visit www.grains.org.
