Evolución de aminas volátiles en dos tipos de merluza (Merluccius australis y Merluccius capensis) y en rosada (Xiphiurus capensis) durante el almacenamiento a -18ºC

Abstract

[ES] Se realiza un estudio de la evolución de aminas volátiles en dos tipos de merluza (Merluccius austraiis y Merluccius capensis) yen rosada (Xiphiurus capensis) durante 4 meses de almacenamiento a -18"C. Se han observado diferencias significativas (p =5 0'05) para la dimetilamina, mientras que para las bases volátiles totales no se observaron diferencias entre Merluccius australis y Xiphiurus capensis. Las diferencias del contenido en bases volátiles totales (rente al tiempo de almacenamiento solo son significativas (p =0'05) para Merluccius capensis y las.correspondientes a la dimetilamina (rente al tiempo, en todas las especies (p=5 0'01). El aumento detectado en el contenido en bases volátiles totales se explica, en cierta medida, por la variación en el contenido de dimetilamina. Se concluye que la dimetilamina es un compuesto químico que refleja los cambios que se producen en las tres especies durante el almacenamiento congelado y se sugiere su utilización en el control de calidad

[EN] The evolution of volatile amines was determined in frozen hake (Merluccius australis and Merluccius capensis) and kinglip (Xiphiurus capensis) stored for 4 months at -18°C. Significant differences for dimethylamine (p =5 0.05) but not for total volatile bases were found between Merluccius australis .md Merluccius capensis. Differences of total volatile bases as a function of storage time were signifKant (p =5 0.05) for Merluccius capensis, and differences for dimeehylamine as a function of time were significant for all species (p =5 0.01). The increase in total volatile bases may be explained by the variation in dimethylamine. It is concluded the dimethylamine reflects chemical changes in the three species during frozen storage, and its use in quality control is suggested
