For more than three decades, the CAIS has conducted innovative research in radiocarbon and stable isotope analytical techniques for the authentication of natural products in foods, flavors and beverages. Over the last ten years, these analytical techniques have been applied to the emerging field of biobase products and biofuels. Biobased products are defined as commercial or industrial products not used for food and feed.
The CAIS were leaders in the development of radiocarbon and stable isotope techniques applied to the “Federal Biobased Products Preferred Procurement Program” in collaboration with the Center for Sustainable Environmental Technologies at Iowa State University. Mandated by the 2002 Farm Security and Rural Investment Act to require federal agencies to preferentially purchase biobased products, those made from renewable-carbon, instead of their petroleum or fossil-carbon equivalent, the USDA published its final ruling on guidelines to identify and evaluate biobased products. From this, the ASTM D6866-05 method for biobased content was developed.
The CAIS continues its development of biobase product research and is instrumental in the continuance of the ASTM D6866 method, now in its D6866-16 (2016) version.
