Abstract
Electronic nose may provide a novel tool for the quality control
purposes of various perishable food products. The aim of this study was to
test the applicability of electronic nose (NST 3320, Applied Sensor, Sweden)
for the quality control of modified atmosphere (MA) packed broiler chicken
cuts stored at different temperature conditions. Microbiological and sensory
analyses as well as headspace gas chromatographic measurements were used as
the reference methods. Fresh broiler chicken cuts packed in the gas mixture
of 80% CO2 + 20% N2 were stored for 14 days at three different temperature
profiles one of which was constant (+6°C) and the others were variable. The
variable temperatures simulated an ideal distribution chain with constant cold
chain and a distribution chain with unfavourable temperature variations.
During the shelf-life study, electronic nose, microbiological and sensory
analyses were used to evaluate the quality of the samples. In addition
concentrations of hydrogen sulphide and dimethyl sulphide in the packages were
determined using gas chromatographic techniques. The results obtained with
the electronic nose and the reference methods were highly consistent.
Electronic nose appeared to be capable of detecting even the early signals of
spoilage in poultry meat.
