Measurement of Sensory Thresholds

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


This chapter discusses the concept of threshold and contrasts the conceptual notion with the idea of threshold as a statistically derived quantity. A simple method for determining detection thresholds based on ASTM method E-679 is illustrated with a worked example. Other methods for determining thresholds are discussed as well as alternative analyses.
