Determination of Anions in Dried Distillers Grains with Solubles

Distillers grains are used as livestock feed because they are an excellent source of energy, protein, and essential minerals that provide three times the amount of nutrients available from grain alone. Because the nutritional composition of Dried Distillers Grains with Solubles (DDGS) can vary from batch to batch, the distillery industry is interested in determining DDGS composition to properly formulate a nutritionally balanced diet for the animal feed industry. This application note demonstrates a new method developed by Thermo Fisher Scientific which is a simple and accurate process to determine inorganic anions (e.g., chloride, sulfate, and phosphate) that contribute to the nutritional composition of DDGS in less than 10 minutes.
