| Crustaceans are harmed rapidly due to the post mortem different processes, specially the dark spot knew as melanosis or enzymatic darkening. Those spots are controlled by the sulfite treatments, but the potential dangers associated with the use of these compounds oblige to develope rigorous control methods. Besides, in these species are observed texture affectations during the storage time, changing to pasty mass and reducing its commercial quality. For these reasons, it was realized a durability study, analizing chemical, microbiological and sensorial parameters to the frozen products raw lobster tails and tail mass. The results indicated a shelf life of 21 months for the lobster tails and 18 months for the tails mass. |
