Luthria3 Kirk Noel6 and Dutt Vinjamooric aUSDA ARS FCL Beltsville MD 20705 6Monsanto Company Ankeny IA 50021 cMonsanto St. Louis MO 63167 Abstract Conventional breeding as well as transgenic approaches constantly strives to make improvements to quality traits such as increasing the percentage of oil and or modifying the oil composition. One of the key challenges faced by the industry is obtaining accurate cost-effective and rapid analysis of oilseeds grains with enhanced quality traits such as total crude fat oil content or a modified oil composition. Reliable crude fat analysis is of paramount importance to oilseed businesses because monetary assessment in the trade of such seeds is based on total oil values. Although several different primary and secondary technologies are available to determine crude fat content in oilseeds there are significant variations in the results reported by different procedures. A comparative evaluation of different grinders Mega-grinder Knifetec Cyclotec Cemotec Mikro mill UDY grinder Brinkmann-Retsch grinding mill and commonly performed crude fat extraction methodologies accelerated solvent extractor ASE supercritical fluid extraction SFE Ankom batch extraction automated Soxtec extraction and classical Butt-tube on the determination of total crude fat content in soybean seeds is presented. The results clearly suggest a need for harmonization of official primary reference methods across different organizations e.g. AOCS AOAC AACC ISO DGF . This is vital for the development of rugged calibrations for nondestructive high-throughput secondary procedures involving near infrared transmittance near infrared reflectance imaging and nuclear magnetic resonance spectroscopy. Strategies aimed at harmonization of methods will aid in the development of successful business opportunities and obtaining fair trade value for the quality-enhanced .
