Distillers dried grains is a co-product of ethanol production. The significant residue of cooked and fermented grain that remains after distillation of the alcohol has a high content of protein, fat, fiber, vitamins, and minerals. It is widely used as animal feed and in other applications.
Assessing the quality of dried distillers grains with solubles (DDGS) is important for bioethanol producers and distillers, poultry and livestock feed manufacturers, for end users in aquaculture and microbial fermentation, and for laboratories involved with sales or regulation at all stages in the value chain.
Laboratories that participate in the AOCS Laboratory Proficiency Program DDGS series demonstrate their ability to assess ash, crude fat, crude fiber, moisture and protein using a number of AOCS, AOAC and NFTA methods in the world’s the world's most extensive and respected collaborative proficiency testing program, providing assurance to internal and external stakeholders.
Analysts who participate in all quarters of the series can apply to be an Approved Chemist. Approval is earned by superior performance during the previous LPP year. Labs with Approved Chemists for the 2020-2021 DDGS series include: Amspec LLC., Cumberland Valley Analytical Services, Eurofins Central Analytical Laboratory Inc. (New Orleans, LA), Eurofins Scientific Inc. (Des Moines, IA), Hahn Laboratories, Inc., Imperial Western Products, Intertek Agri Services, Isotek Laboratories, Inc., SDK Laboratories, Inc., and Thionville Laboratories LLC.
Labs with Approved Chemists are featured in the AOCS Recommended Lab Directory.
