Total lipid content of 20 species of canned meats available in Australia ranged from 2% in chicken (Hormel, USA) to 41% in stewed pork (Ma Ling, China). Total n-3 polyunsaturated fatty acids (PUFA) ranged from 30 in canned chicken (Hormel) to 659 mg/100 g in chicken hot dog (Tulip, Denmark). The 18:2n-6 was the predominant PUFA, ranging from 187 in corned beef (Hamper, Australia) to 2832 mg/100 g in chicken luncheon meat (Tulip). Other main PUFA, in order of concentration, were 18:3n-3, ranging from 14 in canned chicken (Hormel) to 590 mg/100 g in chicken hot dog (Tulip); conjugated 18:2n-6 (CLA) from 1 in chicken (Hormel) to 135 mg/100 g in corned mutton (Colonial, Australia); 20:4n- 6 from 11 in camp pie (Tom Piper, Australia) to 73 mg/100 g in spiced ham (Hormel); and 22:5n-3 from 5 in chicken (Hormel) and chicken luncheon (Almaraai, Jordan) to 45 mg/100 g in stewed pork (Ma Ling). Total saturated fatty acids (SFA) ranged from 598 to 14 660 mg/100 g, with 16:0 predominant followed by 18:0. Total monounsaturated fatty acid concentration ranged between 813 to 20 218 mg/100 g with 18:1 the major fatty acid. Trans 18:1 ranged from 10 to 698 mg/100 g. The canned meats contained 20 and 22-carbon long chain n-3 PUFA at levels comparable with or greater than those in fresh lean meat.
