point of use testing (2)

This e-book (purchase required) covers the most common non-destructive methods used in food quality and authenticity analysis, including machine vision, Spectroscopy, E-nose/tongue, Ultrasonics, and hyperspectral imaging.. While these methods have been in practice for some time, the technological advancements of the last decade have improved the precision and reliability of these tools, making them more popular. 

The book intends to be a research volume giving an overview of the dominant non-destructive methods, including the more novel technologies such as biosensors and terahertz application.  It brings together detailed information on all these most current advances in technology and elucidates their application in food processing. It covers theory, principle, recent advances and practical applications in food analysis.  The book is aimed at students, researchers, food trainers and industry personnel.
