Lack of DDGS guidelines prompts study

By | July 08, 2009
In response to a lack of industry guidelines and recommendations on analytical test methods for the testing of distillers dried grains with solubles (DDGS), a study was conducted to evaluate the efficacy, applicability and the inter-laboratory variation of a number of methods for moisture, crude protein, crude fat and crude fiber in DDGS. The study was sponsored in part by the Renewable Fuels Association, the National Corn Growers Association and the American Feed Industry Association. A report on the study's findings, titled "Evaluation of Analytical Methods for the Determination of Moisture, Crude Protein, Crude Fat, and Crude Fiber in Distillers" by Nancy Thiex has been published in the Journal of AOAC International, Vol. 92, No. 1.
