Evaluation of sea bream (Sparus aurata) shelf life using an optoelectronic nose

► A new nose for the shelf-life assessment of fresh sea bream has been developed. ► Colour changes of the sensor array were characteristic of sea bream spoilage. ► The data of days 4, 7, 9 and 11 were clustered well in four separate sets. ► Chromogenic data correlate with counts of mesophilic and Enterobacteriaceae.
