Time–Intensity Methods

Part of the Food Science Text Series book series (FSTS)


Time–intensity methods represent a special form of intensity scaling that is either repeated at short intervals or continuous. It offers some advantages over a single intensity estimate, giving more detailed information on changes in flavor and texture over time. This chapter reviews the history of these methods, various current techniques, issues, and approaches to data analysis and provides examples of various applications.
