Analysis of Foods and Beverages: Modern Techniques covers the principles and practical applications of selected analytical methodologies in the field of food and beverages. It also gives an informed forecast of developments in this field. The book focuses on developed fields of scanning electron microscopy, X-ray microanalysis, differential laser light scattering, near-infrared reflectance and Fourier transformations, and continuous-flow and flow-injection analyses. It also includes mass spectrometry, nuclear magnetic resonance, and bioassay. This text also describes traditional techniques, such as the various forms of chromatography. Furthermore, the book presents an introduction of molecular analysis of synthetic flavors and the automation of food analysis by use of computers, robotics, and other on-line methods. Students, teachers, researchers, and all food analysts will find this book valuable, as it can provide information on the various modern analytical techniques in the food industry.
