Abstract

This study was investigated to obtain basic data which can be applied to processing of retort pouched seasoned sea mussel. Shell was washed and steamed before shucking. Sea mussel meat was seasoned in boiled and mixed seasoning sauce(soy sauce 23%, monosodiun glutamate 2%, sorbitol 2%, sesame oil 1%, vinegar 2%, starch syrup 15%, water 55%) for 30 min. The seasoned sea mussel was vacuum packed in plastic film bag and sterilized for various Fo values(Fo 7~13 min.) in a hot water circulation system retort at 121℃. The chemical composition such as pH, VBN, amino-N, total amino acid, free amino acid, color value (L, a, b), texture profile, TBA value, mineral, sensory evaluation and viable cells count of the retort pouched seasoned sea mussels sterilized with various conditions(Fo 7~13 min.) were measured.
