Product Details

The authors convey the enormous scope of modern mass spectroscopy as applied to the food industry. They cover the principles of the discipline in the early chapters and applications in food analysis in the later chapters.

Industry Reviews

"... this book has much to interest almost any chemist ..." * Aslib Book Guide, Volume 65, No 9, September 2000 * "... very well-written and useful ..." * Journal of the American Chemical Society, Volume 122, No 42, p 10492 * "... students or graduates of life sciences will find this book very clear and informative ..." * Nahrung-Food, Vol 45, 2001, No 1 * "This book is a useful introduction to the subject for students of food chemistry, nutrition and food safety, and contains much of interest for the specialist." * Journal of the Science of Food and Agriculture, Vol 18, Iss 15, p 1598, December 2001 * "This is an informative volume, which provides a detailed account of the application of MS techniques for food analysis. It is therefore highly recommended for researchers with interests in food compositional analysis, nutrition and food safety." * Carbohydrate Polymers, 50, 2002, 435 *
