Abstract :

Protein components of living body are affected by environmental factors such as temperature, salinity and pH. This study was carried out to measure and compare drip and drip protein in four fishes Pomadasys kaakan, Caranx ignobilis, Nemipterus japonicas and Ctenopharyngodon idella holding condition without and with 2 and 5 percent salt in house refrigerators with -19, 2010. 108 samples of fishes were investigated. Drip was measured using Spectrometer T80 uv/lis PG Instruments and percent of drip protein was done by kjeldahl method. In this study data were analyzed with SPSS17 software in terms of oneaway (ANOVA). According to the results, highest of drip 50.43±14.56 g and drip protein 3.40±1.17 % was in Pomadasys kaakan in5 percent salt and lowest of drip 1.32±0.36 g was in Pomadasys kaakan without salt, respectively. Also, the lowest of drip protein was 2.75±0.46 % in Pomadasys kaakan in 2 percent salt. Salting caused an increase in drip loss (P<0.05) but had no significant effect on drip protein content (P≥0.05).
