Effect of freezing period on chemical composition, microbial load and some pathogenic bacteria of Nile tilapia (Oreochromis niloticus)
This study evaluated the effects of freezing periods on nutritional values, microbial loads, and some pathogenic bacteria in Nile Tilapia (Oreochromis niloticus). 8 kg. Samples were collected from El-mawourda Fish Market in Khartoum State, for four experimental treatments. The treatments were conducted on the period 0 day, 7 days, 15 days and 21 days. It is noticed that the freezing period effect on the nutritional value, microbial load and some pathogenic bacteria of Nile tilapia (Oreochromis niloticus) revealed that the lowest average nutritional assessment of Nile tilapia (Oreochromis niloticus) observed for protein 20% at the third period of freezing (21 days), and minerals were calcium, phosphorus, magnesium, iron, sodium and potassium (5.6 – 2.7%, 4.8 – 2.9%, 2.6 – 2.9%, 1.1 – 0.71%, 4.5 – 2.8%) respectively. The result of this study clarified that the freezing period has a considerable consequence (p ≤ 0.05) on the chemical composition, microbial load and same pathogenic bacteria (E. coli and Salmonella) of Nile tilapia (Oreochromis niloticus).
