An accelerated system for screening of process variables and freshness indices of irradiated fishery products

Abstract
Summary: Incubation of fish homogenates at 30°C led to enhancement of microbial growth and other freshness indices like TMA and TVBN values enabling rapid screening of process variables. This accelerated test system was found to be successful when applied to shrimps and four species of locally available fish, viz. Indian Salmon (Eleutheronesma tetradactylum), Surmai (Scomberomorus gettatus), Pomfret (Stomateus cinereus) and Bombay duck (Harpodon nehereus); which were either untreated or subjected to gamma radiation with or without combination of sodium nitrite and benzoic acid.
