Abstract

Whole frozen-thawed shrimp (Pandaleus borealis K.) was dipped into 1.25% of sodium metabisulphite solution and stored in ice and ice slurry for 7 days at 2-3°C. The effect of sodium metabisulphite on melanosis development was assayed by sensory analyses and bacterial counts. Spoilage bacterial growth, pH, TVB-N, TMA and sulphite were monitored for comparison. Sodium metabisulphite showed strong properties of delaying melanosis development and its antimicrobial effect was demonstrated when the shrimp was held in ice. However no effect on microbial reduction was observed when sodium metabisulphite treated shrimp was kept in ice slurry.
