ne of the most pervasive problems in chemistry is the separation of complex materials into component parts, either to characterize a mixture or natural product or to remove a particular component from the matrix. This new book chronicles the exciting developments in supercritical fluid extraction and chromatography, particularly as applied to food systems. You'll gain in-depth knowledge on the history, current research, instrumentation, applications, and trends in this rapidly evolving field. You'll benefit from the expertise of some of the most prominent researchers working in supercritical fluids. Supercritical Fluid Extraction and Chromatography offers viewpoints from academia, government, and industry. Anyone working in the foods and flavors industries will find this volume a musthave resource. Bonnie A. Charpentier and Michael R.
