Interpretive Summary: During the past two decades there has been remarkable advancement in the filed of Biotechnology. The first phase of genetic engineering in crops was centered on agronomic traits whereas the current trend focuses on value added traits such as oil or protein content modifications or yield enhancement. This biotech advancement in conjunction with the globalization in trade has resulted in development of new opportunities and challenges that are faced by the industry and society. Appropriate valuation and differentiation of these value added quality products across the globe pose a major challenge faced by large number of industries and other grading organizations in different regions of the world. This is caused by differences in the technologies and procedures approved by various official agencies for the assay of value added traits. Accurate determination and proper assessment of the value-enhanced products is critical for the success of the biotech industry in global market place. There is a crucial need for harmonization of assay procedures across different official agencies around the globe. This books attempts to address these issues by taking crude fat as an example, this approach can be extended to other value added products.
Technical Abstract: The topic of 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 AOCS Annual Meeting in Kansas City, MO in May 2003. This book contains represented paper from this symposium. This book is divided into five sections: Section 1 deals with the economic significance of accurate determination of crude fat and a need for harmonization of procedures across different official agencies. Section 2 describes in detail the different extraction technologies and their principles that have been used for crude fat content determination. These technologies can be used extended to other products too. Section 3 compares different extraction technologies and identifies the importance of sample prep and issues related to crude fat analysis. Sections 4 and 5 depicts current and emerging secondary rapid non-destructive technologies (NIR and NMR) used for crude fat determination.
