Sensory analysis of different aquaculture gilthead sea bream (Sparus aurata L.) commercial presentations
Abstract
The analysis or sensory test may be defined as an analysis of food by means of the senses. Such sensory evaluations have been used from ancient times to accept or reject food, as well as to designate its commercial value. Sensory analysis provides two important advantages: it is quick and it is simple. However, the senses which give rise to acceptance or rejection do vary over time and at the moment of perception. This depends as much on the person as on the environment. A reliable measure requires objectivity and normative regulation of terms and conditions that can influence specific evaluations. The current study has carried out sensory analysis of four different githhead sea bream presentations (whole, fillets, vacuum packed fillets, and marinated in lemon juice and vacuum packed fillets). The study was done as a quality test in order to determine the moment in which the fish is organoleptically rejected. In the four presentations, the scores given for freshness, decreased linearly according to time spent in ice. The taste panel members found the whole, the filleted and the vacuum filleted sea bream organoleptically unacceptable by the 22nd day on ice. Nevertheless, marinated sea bream were not so considered by the 22nd day.Downloads
