PRELIMINARY STUDIES ON THE EFFECT OF IRRADIATION AS A MEANS OF PRESERVATION OF FISH AND SHELLFISH

Abstract

Preliminary investigations on the effect of irradiation on
commercially important fish and shell fish like silver pomfret.
Bombay duck and prawns were conducted. Irradiated samples had
an extended storage life compared to their respective controls even
though yellowish or brownish discoloration occurred earlier in
irradiated fish. Irradiation enhanced the rate of drip formation.
Brine treatment prior to irradiation retarded this rate. Pre-blanching
was found to further extend the storage life of irradiated fish.
