Food Analysis Theory & Practice (Paperback)

In preparation of the manuscript, we followed the recommendations for subject coverage in a textbook of food analysis for students of food science and technology.

Basic principles are stressed, rather than details of analytical methods. Although the emphasis has been on modern and sophisticated instruments and methods, we have described also the classical procedures that have been in use for many years. In chapters devoted to instrumentation, we have attempted to provide the background theory that is required for understanding the principles of each instrumental assay. Included are diagrams and descriptions of typical instruments, information on their application and precision, and sample problems with detailed solutions.

In the sections devoted to applications, qualitative and quantitative aspects of the basic instruments and procedures are discussed in terms of their numerous analytical and instrumental procedures.

This book has been designed for use as a text by undergraduate students majoring in food science and technology, and as a survey of modern analytical techniques and instruments for the worker and researcher in the field of food analysis.
