✦ Synopsis

A number of analytical detection methods for the irradiation treatment of foods have been developed in recent years. Most of these methods require relatively expensive equipment and/or extended sample preparation time. Therefore, simple and low-cost tests would be of advantage to rapidly screen foodstuffs for evidence of their having been irradiated. Two such rapid approaches are described in this contribution: one promising test is the microgel electrophoresis of single cells ("comet assay") which visualises DNA fragmentation in irradiated foods and the second test is the estimation of radiolytic formed gases such as carbon monoxide and hydrogen in irradiated meat by simple electrochemical gas sensors.

Several methods have been described for the detection and quantification of polygalacturonase (PG) and pectin lyase (PL) activities. The most frequently used tests are the Nelson method using copper(II) and an arsenomolybdate reagent to detect PG activity, and the colorimetric method using thiobarbi
