FREITAS PIRES, Caroline Roberta, et al. Lipid profile and nutritional quality of canned fish species in vegetable oil: matrinxã (Brycon amazonicus) and freshwater sardine (Hemiodus unicamculatus).

Given the need to satisfy the demand for fish consumption, canned native fish has emerged as a market alternative, but it is necessary to determine the nutritional aspects of this product. The aim of this study was to characterise the lipid profile and evaluate the nutritional quality of matrinxã preserved in vegetable oil and compare these results with freshwater sardines obtained from the same type of processing and canning. Matrinxã species had higher protein content than sardines, but sardines had higher levels of moisture, lipids and total minerals. The predominant fatty acid in the canned fish samples was linoleic acid, followed by oleic acid and palmitic acid. In terms of nutritional quality, matrinxã showed higher indices of atherogenicity and thrombogenicity and lower values of the following ratios: hypocholesterolemic and hypercholesterolemic fatty acids; polyunsaturated/saturated and omega 6/omega 3 ratio in relation to sardines. In view of the results, it can be affirmed that Matrinxã, from a nutritional point of view, presents itself as a good alternative for the canned fish industry.
