This Symposium on Modern Methods of Food Analysis was the sev enth in a series of basic symposia, begun in 1976, on topics of major importance to food scientists and food technologists. The Symposium, sponsored jointly by the Institute of Food Technologists and the In ternational Union of Food Science and Technology, was held June 17 and 18, 1983, in New Orleans immediately prior to the 43rd annual 1FT meeting. Like the other six basic symposia, the program brought together outstanding speakers, from biochemistry, chemistry, food science, microbiology and nutrition, who are at the cutting edge of their specialty, and provided a setting where they could interact with each other and with the participants. The Symposium and this book are dedicated to the memory of George F. Stewart (1908-1982) who made so many important contributions to the field of food science, including that of food analysis. Bernard S. Schweigert has documented George F. Stewart's contributions in the Dedication of this book.

Techniques in Analytical Chemistry
How to evaluate and validate data from chemical measurements in biological systems—a unique overview

An understanding of chemical measurement processes in biological systems is essential to working in today’s life-science and biotechnology industries. This work provides analysts and laboratory professionals with the fundamental knowledge and basic principles they need to tackle the measurement process in the real world. Rather than rehashing traditional analytical techniques, which can be problematic for biological samples, the book emphasizes the highly complex nature of biological systems through such topics as enzyme measurements, enzymes as reagents, immunochemical assays, and assay validation and quality control. It provides a complete overview of principles and methods proven useful in biological systems—from pH, buffers, and spectrophotometry to basic chromatographic techniques. With Chemical Measurements in Biological Systems as their guide, readers will understand the basic principles needed to:

• Read and evaluate an assay method description
• Choose the appropriate method from the vast array of available techniques
• Modify and evaluate an existing method for specific needs
• Set up and run biochemical assays
• Use multistep problem-solving techniques
• Evaluate the results of a given assay in a given matrix
