摘要

Fishes are suitable for sun drying and smoking. But their high contains of unsaturated fatty acids mak</span><span style="font-family:Verdana;">e</span><span style="font-family:Verdana;"> them very prone to lipid oxidation. However, some plants are rich in natural antioxidants and have been shown to be potent inhibitors of lipid oxidation during processing of meat. The effect of three aqueous plants extracts on lipid stability of </span><span style="font-family:Verdana;"><i></span><i><span style="font-family:Verdana;">Oreochromis niloticus</span></i><i><span style="font-family:Verdana;"></i></span></i><span style="font-family:Verdana;"> collected in Far-North Cameroon during processing was evaluated. Results show the high nutritious of these fish with high levels of proteins, lipid and ash (71.02</span><span style="font-family:Verdana;">%</span><span style="font-family:Verdana;">, 13.71</span><span style="font-family:Verdana;">%</span><span style="font-family:Verdana;"> and 10.65%, respectively). It has been observed that oleic acid (C18:1), followed by palmitic acid (C16:0) and linoleic acid (C18:2) are the most dominant fatty acids present in </span><span style="font-family:Verdana;"><i></span><i><span style="font-family:Verdana;">Oreochromis niloticus</span></i><i><span style="font-family:Verdana;"></i></span></i><i><span style="font-family:""> </span></i><span style="font-family:Verdana;">lipids. Their lipid also showed a much higher content of omega-3 polyunsaturated fatty acids (PUFA) compared to omega 6 PUFA. The total phenolic contents (TPC) of the three plants ranged from 12</span><span style="font-family:Verdana;">,</span><span style="font-family:Verdana;">150 to 16</span><span style="font-family:Verdana;">,</span><span style="font-family:Verdana;">050 mg/100</span><span style="font-family:""> </span><span style="font-family:Verdana;">g.
