A History of the Development of Sensory Methods for the Evaluation of Freshness of Fish

It is well-established in fish technology that freshness should be measured primarily by sensory procedures, though considerable effort has been expended in looking for nonsensory alternatives. A variety of methods for sensory evaluation of freshness has been described and this historical review traces developments of these methods. Much of the source material derives from the research literature such as research journals and reports of research, and the use of sensory methods in commercial quality control has scarcely been documented. There is a brief discussion of possible future developments in sensory evaluation of freshness.
