Abstract
The measurement of ‘freshness’ has proved to be elusive and there are still no widely agreed objective methods for its determination. We point out that the reasons for this are several: (1) conceptual, (2) measurement of time elapsed since death at a set temperature is insufficient, and (3) no test so far proposed has the correct characteristics.We put forward a system in which ‘freshness’ can be carefully defined and various criteria and methods can be specified and agreed on by all interested parties.This system overcomes the terminological and conceptual difficulties that exist when the term ‘freshness’ is used. Furthermore, we outline the characteristics that a test should possess and discuss the reasons why many proposed measures fail to be used in practiceKeywords
