Abstract
The incidence of black spot in frozen prawns was observed in many cases
during thawing at tropical ambient temperatures. A dip in 0.5% (100% purity basis)
sodium metabisulphite solution for 30 seconds controlled black spot in frozen
Metapenaeus monoceros upto 10 months. Phenoloxidase activity in the shell extract
of prawn showed a decreasing trend during frozen storage (-180C). The activity
was lower in the sulphite treated sample when compared with the untreated sample.
Residual sulphur dioxide in thawed meat was within permitted limits.
