[Technological innovation applicable to marine oils rich in n-3 fatty acids to allow their nutritional and pharmacological use: a challenge for the present decade].
The important physiological properties described for marine oils rich in n-3 polyunsaturated fatty acids have give rise to increasing efforts to develop procedures for obtaining, preserve and concentrate these oils aiming its nutritional and pharmacological use. The fish meal industry provides high quantities of fish oil, however this oil being not suitable for human consumption must be subjected to different refining procedures to allow its use for feeding purposes. This review describes the current research about the employment of different procedures to incorporate n-3 polyunsaturated fatty acid to our feeding. The feasibility for the application of chemical methods and stereospecific enzyme-transesterification procedures for obtaining oil concentrates, and the use of natural substances for stabilizing the oil against oxidation are discussed. The possibility that some birds such as the chicken, feeding a diet rich in n-3 polyunsaturated fatty acids, as a healthy, safe and suitable vehicle to provide these fatty acid for human nutrition is also discussed.
