摘要: Whole (deheaded and eviscerated) channel catfish were dipped in 1 or 2% lactic acid sodium percarbonate (Pergenox ®). fillets also washed with high-pressure water 8% tripolyphosphate (STPP). Impedance detection time (IDT) was recorded for rinsates of the products. Fish had higher initial IDT than those % acid. Regardless concentration, same products held more one day at 4C. Similar results achieved Pergenox®. Fillets spray-washed STPP water; difference being pronounced after six days For whole fish, a very significant reduction microbial counts (higher IDT). Exposing product to spray wash short did not have effect on IDT, but addition increase thus shelf-life.
