Sažetak
Whole Atlantic mackerel (Scomber scombrus), sardine (Sardina pilchardus), and Mediterranean hake (Merluccius merluccius) from the Croatian Adriatic were stored at 22º ; C and changes in histamine, putrescine, tyramine, and cadaverine levels were monitored in relation to bacterial endotoxin. After 12 h, histamine level in sardine was above the legal limit of 50 mg kg-1, set by US Food and Drug Administration, and an increase in putrescine content preceded the increase in histamine. After 24 h, histamine contents in mackerel and sardine reached 1090 ± ; 101 and 577 ± ; 275 mg kg-1, respectively, which exceeded the toxic threshold. At the same time, the putrescine content was also high in both fish (353-420 mg kg-1). The time-course of endotoxin production was similar in all fish species stored at 22º ; C. A high correlation was found between endotoxin and histamine, and between endotoxin and putrescine in mackerel and sardine. On the other hand, high endotoxin level in hake, after 24h, was associated with the low histamine and putrescine content (40-60 mg kg-1).
