This book contains papers from the symposium "Critical Issues, Current and Emerging Technologies for Determination of Crude Fat Content in Food, Feed and Seeds," held in 2003 at the AOCS Annual Meeting in Kansas City, Missouri. The topics covered give a broad perspective of the challenges and issues of the value-added enhanced products. This book will be of interest to biotechnology professionals, processors, scientists, nutritionists, economists, new product development and business professionals, official agencies, and others actively engaged in the development and marketing of value-added products.
