Abstract
ABSTRACT: Ascorbic acid, citric acid, sodium benzoate, kojic acid, and 4‐hexylresorcinol were evaluated alone and in combination as inhibitors of melanosis and microbial spoilage in prawns (Penaeus japonicus) under non‐pressure and high‐pressure conditions. Sodium benzoate and kojic acid was an effective combination for the inhibition of prawn melanosis. Alone and in combination with ascorbic or citric acid, 4‐hexylresorcinol proved the most effective as inhibitors of melanosis and microbial spoilage in prawns. High‐pressure treatment appeared to increase the melanosis process, but it did not alter the effect performed by inhibitors. Lower total count of microorganisms seemed to be obtained with the presence of ascorbic and citric acids under high‐pressure treatment.
