This study aimed to use refined sardine oil as a covering juice in canned Sardina pilchardus. The oil's fatty acid profile, acidity, peroxide value, and p-anisidine value were analyzed. The biochemical composition, histamine content, and bacteriological stability of the canned sardines were determined. The results showed that canned sardines contained 51.40 g of moisture, 27.87 g of fat, 17.91 g of protein, and 1.03 g of salt per 100 g net weight. The fatty acid composition included 10.35% polyunsaturated fatty acids, 8.86% saturated fatty acids, and 6.27% monounsaturated fatty acids, with the most abundant fatty acids being eicosapentaenoic acid (EPA), palmitic acid, oleic acid, myristic acid, and docosahexaenoic acid (DHA). This recipe provided 8.88 g/100 g (net weight) of EPA and DHA. These findings support the interest in using refined fish oil to enrich foods with essential marine fatty acids, highly recommended for their health benefits and leading to encouraging prospects for sardine canneries to develop new and nutritious value products.
