Evaluation of some quality indices in farmed fish from Kafr Elshiekh governorate

Abstract

Evaluation of some quality indices was carried out to determine the nutritional value of the most cultured freshwater fishes and to estimate the tolerance of these items to remain in good condition against damage. Quality indices were evaluated in 90 samples from three different fish species (Mugil cephalus, Oreochromis niloticus and Clarias gariepinus) 30 of each were collected at different times from different farms in Kafr Elshiekh Governorate, Egypt. Results of pH, total volatile nitrogen (TVN) "mg N /100g", trimethylamine (TMA)" mg /100g", thiobarbituric acid (TBA)" mg/kg" and peroxide value (PV)" meqO2/kg" were 6.

“…(2023) for determining the extent that a fat has degraded to non-metabolizable aldehydes, such as malondialdehyde (MDA). As fat content increases, the peroxide number or value in the TBARS test increases (Elsherief et al, 2019). Samples of fish fillets were weighed, and a solution of 2 M orthophosphoric acid was combined with 25ml of 20% trichloroacetic acid.…”
