1. The cleaning effect on jack mackerel (Trachurus trachurus) was examined with different surface active agents, such as sodium linear alkylbenzene sulfonate (LAS), sucrose fatty acid ester (SE), and polyoxyethylene (9) fatty alcohol (C16-18) ether (PEFA). The surface active agents were dissolved in phosphate-citric acid buffer of different pH values.
2. Cleaning of fish with PEFA and LAS at pH 5.0 resulted in a clean surface appearance and the removal of unpleasant fishy odour. But the skin surface treated with LAS turned buff colour within 1-2 days after cleaning.
3. Viable bacterial counts on the skin surface decreased to 1/100-1/1000 after cleaning with PEFA solution at pH 5.0. No other surface active agents tested showed similar effect.
