Elimination of vibrio cholerae El Tor, in scallops (Argopecten purpuratus) by gamma radiation and product organoleptic evaluation; Eliminacion de vibrio cholerae, El Tor, en conchas de abanico (Argopecten purpuratus) con el uso de radiacion gamma y evaluacion sensorial del producto

Abstract

V. cholerae D{sub 10} value in scallops (Argopecten purpuratus) was determined in vivo. D{sub 10} was found to be 0,143 kGy, requiring therefore the application of 8D in scallops, equivalent to a 1,14 kGy dose, the optimal dose for life span extension of samples kept under refrigeration conditions (0-1{sup o}), and examined periodically under different analytic method criteria. Life span for the appearance characteristic reaches the acceptability limit of 3, after 11 days for control samples, and 16 and 13 days for samples radiated at 1 and 2 kGy. Smell of control samples was accepted only until the 13{sup th} day while samples radiated at 1 and 2 kGy went beyond this level, reaching 19 and 17 days respectively. In the same way, life span for the flavor characteristic was extended to 19 and 20 days for samples radiated at 1 and 2 kGy, respectively, while control samples only reached 15 days. Control sample texture remained within acceptable limits until the 18{sup th} day, whereas samples radiated at 1 and 2 kGy reached 21 and 17 days, respectively. Use of ph and nitrogen volatile bases were also evaluated as quality indicators. (authors) 14 refs., 3 figs., 3 tabs., 1 ill.
