Adicionar Tag | Resumo: | In the food field, the aquaculture industry has maintained its development in the use of raw materials from the processing of fish species of marine origin being flour and fish oil cornerstones of this industry for its nutritional value. In the case of fish oil has a high content of polyunsaturated fatty acids (omega 3 PUFA) and also used as food for human consumption. Paradoxically, the high content of n-3 PUFA from fish oil makes a raw material highly susceptible to autoxidation processes which promote the conversion of fatty acid peroxides, aldehydes, ketones and polymers responsible for oxidative cell damage in aquatic organisms for that reason, it is necessary to establish certain quality standards and to do this work aims to compare qualitatively the profile of fatty acids present in three trademarks of fish oil used as a food supplement for growing white shrimp L. vannamei .Puerto Hualtaco, Puerto Jelí, and Puerto Bolivar: To perform this research fish oil samples three trademarks used in several major producing centers of the Province of El Oro was taken. These samples were subjected to analysis of the profile of fatty acids, moisture, iodine, peroxide and total lipids along with purity. The results of the three samples analyzed in this study indicate that present good quality for aquaculture use, regardless of site preparation. |
