수산식품가공소재로서 시판 적색육 어류[고등어(Scomber japonicus), 삼치(Scomberomorus niphonius), 청어(Clupea pallasii)]의 화학적 위생특성

Abstract

This study examined chemical characterization in commercial dark-fleshed fish (mackerel Scomber japonicus, Japa nese Spanish mackerel Scomberomorus niphonius, and Pacific herring Clupea pallasii) to determine their suitability for use as raw materials for seafood products. The volatile basic nitrogen (VBN), heavy metal, radioactivity, poly chlorinated biphenyl (PCBs), benzo[a]pyrene, and histamine concentrations were measured. The VBN in all of the dark-fleshed fish was less than 20 mg/100 g, which is the limit for raw materials for seafood processing. Except for mackerel based on the lead (Pb) standards of the European Union (EU), Taiwan, and CODEX, and all fish based on the cadmium (Cd) standards for China and the EU, the commercial dark-fleshed fish were free from total mer cury (Hg), Pb, and Cd based on domestic and foreign standards. The radioactivity, polychlorinated biphenyl (PCB), benzo[a]pyrene, and histamine concentrations of the commercial dark-fleshed fish all adhered to the domestic and foreign standards. The commercial dark-fleshed fish tested could all be used as raw materials for seafood products, except for some exported products.
