Biogenic amines formation in seer fish (Scomberomorus commerson) steaks packed with O2 scavenger during chilled storage

A comparative study of the effect of O2 scavenger on the formation of biogenic amines during chilled storage of seer fish (Scomberomorus commerson) was carried out. O2 scavenger was effective in reducing the O2 content of the pack up to 99.95% within 24 h and it extended shelf-life up to 20 days compared to only 12 days for air packs. The biogenic amine content increased significantly (P < 0.05) in air packs compared to O2 scavenger packs. Histamine, putrescine and cadaverine reached maximum levels of 6.8, 14.6 and 14.7 μg/g, respectively, in air packed samples at the end of 15th day. Spermidine and spermine levels increased slightly and did not change much throughout the storage period. Agmatine was absent in the O2 scavenger packs throughout the storage period, whereas tyramine was observed only towards the end of storage study.
