Fresh oil sardine, mackerel and prawn were dipped in 0.1% and 1% solutions of Na sub(2)EDTA, and stored in ice. Their storage-life was assessed by bacteriological, chemical and sensory methods. Even though EDTA treatment controlled the increase in bacterial counts and reduced TMA and TVBN production in oil sardine and mackerel, the consequent beneficial effect was not realised because of the deterioration of fat in these fishes, leading to rancidity. But, for prawn stored in ice, a dip in 1% solution of Na sub(2)EDTA enhanced the shelf-life by at least 8 days over the untreated control. EDTA absorbed by the muscle of fish and prawn during dip in Na sub(2)EDTA solution is not completely removed during their iced storage for 25 days.Journal
