Evaluation of the Food Sniffer electronic nose for assessing the shelf life of fresh pork meat compared to physicochemical measurements of meat quality

摘要

In food technology applications, electronic noses have been used on the on-line control of different processes. In this study, assessment of shelf life of fresh pork meat that had been stored under refrigeration in aerobic conditions using an electronic nose pocket device was tried. The physicochemical, sensory, and microbiological parameters of white female pork tenderloin, stored at 4 A degrees C for 7 days, were related to the response obtained with an electronic nose device (Food Sniffer(A (R))) (FS) to validate its possible use as a rapid method of determining the shelf life of meat. The response of the electronic nose device, qualitatively validated, was significantly correlated with some parameters as microbiological counts or sensory parameters; unfortunately, tight quantitative limits between FS response and some analytical results as biogenic amine content could not be related.
