Abstract
The enzyme, polyphenoloxidase, is responsible for the black spot formation in prawn.
Sulphiting agents such as sodium metabisulphite and sodium bisulphite are widely used
in prawn processing factories to control black spot, but sensitive persons are allergic to these
chemicals. Repeated washing with optimum volume of potable water helped to leach out
polyphenoloxidase from prawn considerably. 92% of the enzyme was leached out in the
first two washing in the case of headless shell-on prawn and 53% was leached out in case
of shell on whole prawn
