摘要：

Fish oil-origin eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are encapsulated with formulated alginate to prevent biohydrogenation in the rumen. Beads are formulated with 0.3%, 1.0%, and 2.0% of alginate. Bead surface poreformation is characterized by environmental scanning electron microscopy (ESEM). Observed pore sizes according to alginate concentration are 17-33 mu m (0.3%), 1018 mu m (1.0%), and 5-10 mu m (2.0%). Release of EPA and DHA is evaluated during ruminal, abomasal, and intestinal simulated digestion. Beads shows high percentage of encapsulation efficiency (91.39% from EPA and 93.51% from DHA). Beads designed (1.0%) allows to obtain EPA release of 13.65% (ruminal digestion), 29.07% (abomasal digestion), and 28.21% (intestinal digestion); while, DHA releases under the same conditions are: 18.55%, 26.78%, and 43.16%, respectively. Beads with 1.0% of alginate had the best release pattern during ruminal simulated digestion allowing an increased intestinal availability of EPA and DHA. Practical Applications: Fish oil encapsulation into alginate beads is a good alternative for ruminant diets supplementation, which will allow to get animal origin food (milk and meat, mainly) enriched with essential fatty acids such as EPA and DHA.
