Abstract
The results of investigations to develop an equipment for testing frying fa ts based on an "electronic nose" are presented. A practical approach was found for a handheld test instrument by means of h eadspace-gas chromatography (GC)-measurements of frying fats. Some sensors with the appropriate characteristics and selectivity were selected from a w ide range of metal oxide sensors manufactured by different companies. First measurements with prototype probes resulted in a good correlation wit h the Food Oil Sensor as a reference. The influence of the water in the oil could be compensated. Different types of food did not influence the result s.
