During the last ten years, several new extraction techniques have been developed that are faster, more automated and use less organic solvents compared to classical solvent extraction techniques. Furthermore, there is a clear trend going towards the use of (and research on) environmentally sustainable methods, which is encouraging for the future. Supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE) are two of the most useful techniques for extraction of non-polar and medium polar solutes from solid and semi-solid samples. These techniques commonly use pressurized carbon dioxide or hot liquids such as water as extraction solvents, respectively. For aqueous samples, stir-bar sorptive extraction (SBSE) has recently been developed. These are some of the techniques that will be described in the proposed symposium series book. Focus will be on the extraction of various compounds from food and agricultural samples in either an analytical or a process-scale point-of-view. Several of the book chapters will compare the different techniques, and describe their advantages and disadvantages. Applications discussed in this book include SFE of biopolymers from distillers dried grains, SFE of lipids from oilseeds, PLE of functional ingredients from plants and herbs, tandem SFE/PLE of acrylamide from potato chips, SFE and PLE of cholesterol and fat from hamster liver, and steam distillation-extraction (SDE) and SBSE of flavors from shitake mushrooms.

Extraction is a process that is growing in importance. It is generally more energy efficient than competitive processes such as expression-the pressing of biological feed materials to liberate fluids. The high cost of modern extraction techniques and the increasingly stringent environmental regulations together with the new requirements of the medical and food industries for ultra-pure and high value added products have pointed out the need for the development of new and clean technologies for the processing of food products. The food processing industry uses various techniques to transform food ingredients into different forms for consumers. Separation techniques may be used to remove skins from fruits, water from juices, or whey from cheese. Each separation technique is customized to the amount of waste that needs to be removed, and the resiliency of the food product being processed. This is the fundamental reason for writing this book at the present time, to indicate the wealth of knowledge becoming available on reactions in food processing, and the use of reaction technology to apply this knowledge in food processing.

While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork.
