l‐Lactic acid, sodium bisulfite, and 4‐hexylresorcinol were evaluated, alone and in combination, as melanosis and microbial spoilage inhibitors on brown shrimp (Penaeus aztecus). No effect on the microbiological shelf life of treated shrimp was observed. 4‐Hexylresorcinol functioned exceptionally well as a melanosis inhibitor, alone and in combination with. l‐lactic acid. However, extensive bacterial growth was demonstrated in the 4‐hexylresorcinol dip solution during normal storage on deck, creating the potential for a heavy bacterial inoculation of shrimp during a typical dipping process. Addition of l‐lactic acid to the 4‐hexylresorcinol dip solution prevented bacterial growth in the dip solution and did not diminish melanosis inhibition. Copyright © 1994, Wiley Blackwell.
