Farmed catfish (Clarias batrachus Linnaeus) and red tilapia (Oreochromis sp.) were stored at ambient temperature (28 plus minus 2 degrees C) for a period of 24 h. They were evaluated for acceptability freshness deterioration rancidity development and microbiological changes. Raw catfish was acceptable up to 20 h and that of tilapia up to 15 h. Upon rejection their K1 values were 70.0 and 42.7 percent for tilapia and catfish respectively. Microbiologically catfish samples did not exceed the 10 strength seven cfu/g limit until the end of the storage period; however tilapia was not acceptable by the 20th hour.

Abstract

Farmed catfish (Clarias batrachus Linnaeus) and red tilapia (Oreochromis sp.) were stored at ambient temperature (28 plus minus 2 degrees C) for a period of 24 h. They were evaluated for acceptability freshness deterioration rancidity development and microbiological changes. Raw catfish was acceptable up to 20 h and that of tilapia up to 15 h. Upon rejection their K1 values were 70.0 and 42.7 percent for tilapia and catfish respectively. Microbiologically catfish samples did not exceed the 10 strength seven cfu/g limit until the end of the storage period; however tilapia was not acceptable by the 20th hour.
