Abstract

The purpose of this study was to collect basic data that could be used in the manufacture of two kinds of canned oyster Crassostrea gigas. The steamed oyster was prepared by shucking after boiling for 6 min at 105℃ and then washing and dewatering. The roasted oyster was prepared by baking steamed oyster at 140℃ for 20 min. The manufacturing methods of canned seasoned boiled oyster and canned seasoned roasted oyster were as follows. The boiled or roasted oyster (50 g) was added to a can (RR-90) along with a mixture of seasoning sauce 40 and then seamed using a vacuum seamer under 20 cm Hg after pre-exhausting at 90℃ for 20 min. The two kinds of canned oyster products produced under sterilization of Fo 12 min were tested for cultured bacteria, external appearance, proximate composition, pH, VBN (Volatile basic nitrogen), TBA (Thiobarbiuric aicd) value, amino-N, salinity, color value sensory evaluation, etc. Results showed that the canned seasoned roasted oyster had higher overall acceptability than the canned seasoned boiled oyster. The reason for this was judged to be that the process of roasting at 140℃ for 20 min influenced the sensory evaluation.
