The topic of accurate determination of oil content in oil seeds is of significant
interest to the members of the AOCS and is strongly supported at the organization
level. A symposium entitled “Critical Issues, Current and Emerging Technologies
for Determination of Crude Fat Content in Food, Feed and Seeds” was held at the
AOCS Annual Meeting in Kansas City, MO in May 2003. This book contains represented
papers from this symposium.
The book is divided into five sections: Section 1 deals with the economic significance
of accurate determination of crude fat and the need for harmonization of
procedures among different official agencies around the world. Section 2 describes
in detail the different extraction technologies and their principles that have been
used for crude fat content determination. These technologies can also be extended
to other products. Section 3 provides a comparison of different primary extraction
technologies and identifies the importance of sample preparation and issues related
to crude fat analysis. Sections 4 and 5 depict current and emerging secondary rapid
nondestructive technologies (e.g., NIR and NMR) used for crude fat determination.
