Utilización del aceite de hígado de tiburón obtenido en Cuba en el desarrollo de productos nutricionalmente mejorados

摘要: During the last few years, there has been great interest in study of marine lipids because their composition, and especially omega-3 polyunsaturated fatty acids as they form part basic cellular structures intervene metabolic processes mammals. The lipid composition acid profile neutral polar fraction was determined by TLC-Iatroscan, Gas Chromatography, shark oil obtained from a pool livers following species: Ginglimostoma cirratun, Carcharhinus longimanus, C. falciformis captured Cuban waters. Two processes, emulsification, microencapsulation were applied to increase stability. for emulsion microencapsulated effect treatments evaluated. Shark mainly Triglycerides (97.2 %) small concentration phospholipids (0.3 %). Twenty one identified fraction, 18 ones represented 26.5 % total liver oil. Emulsification do not significantly affect composition; contrast reduce oxidation, stability 150 days. milky drinks enriched with microencapsulate They evaluated good acceptance group consumers cover 4-12% daily requirement EPA 15-51% DHA. incidence on patient high blood pressure, triglyceride fenilcetonuric supplementation its diet. economic evaluation showed feasibility productions at industrial scale.
