Abstract
Canned sardine is widely consumed in Egypt because it is a cheap, delicious, rich source of high quality easily digestible protein, minerals, vitamins and omega-3 fatty acids. Therefore, a total of 30 samples of locally and imported canned sardines (15 each) were collected within their validity date from different markets at new Damietta city, Egypt for chemically evaluation. The mean moisture, protein, fat and ash values for locally canned sardine samples were 61.02, 22.64, 12.64 and 1.49 respectively. The mean moisture, protein, fat and ash values for imported canned sardine samples were 56.72, 18.55, 24.01 and 3.00. Protein content of local canned sardines is significantly higher (P<0.05) than for the imported once due to the locally canned sardine is manufactured from the sardine fillet only. The mean sodium chloride, total volatile nitrogen and histamine content values for locally canned sardine samples were 1.85, 35.65 and 11.89 respectively. The mean sodium chloride, total volatile nitrogen and histamine content values for imported canned sardine samples were 1.23, 31.79 and 11.28 respectively. The mean concentration levels of cadmium in the locally canned sardine were 0.03 and 0.09 ppm respectively. The mean concentration levels of lead in the imported canned sardine were 0.162 and 0.299 ppm respectively. The results of the current study indicated that there are no differences in the chemical quality between locally and imported canned sardine samples under investigation. Both at high range are going to fit the Egyptian Slandered permissible limits in concern to chemical analysis profiles. from that it could be recommend that: Strike monitoring of chemical quality of the canned sardine traded at the markets to control their nutritive values, safety and quality.
