Ethanol Protein – Importance of Co-Product Quality

Why is the importance of ethanol protein co-product quality? At least eight ethanol plants have recently installed new process technology that separates higher value corn fermentation protein from whole stillage. This ethanol protein is a combination of corn protein and yeast protein from the ethanol fermentation process. This protein product is destined for growing animal…
