Biochemical aspects of the spoilage of prawns
1965
Velankar, N.K.
Certain features characterise spoilage of sea foods, as distinct from spoilage of protein foods in general. Among sea foods spoilage differs in the crustaceans, teleosts, or elasmobranchs respectively. High levels of free amino acids concentrations are characteristic of prawns and other crustacean muscle. Changes occurring in these influence pattern of spoilage. Differences also exist in the sea prawns and prawns taken from the backwaters. Melanosis is a characteristic feature of spoilage in prawns. Observations have shown that prawns are very susceptible to spoilage at ordinary temperature, the period of absolute freshness not exceeding 4 hours, while prompt icing extends the period to 3-5 days.
