N2 - The resistance of polymeric capsules in sheep ruminal fluid was evaluated for possible application as a vehicle of bioactive agents to be released in the stage post-ruminal. Capsules were made by ionic gelation, using sodium alginate as wall material in combination with biopolymers and chlorophyll as a bioactive agent. Chlorophyll release and digestibility of biomaterials were evaluated in vitro conditions using sheep-ruminal fluid and digestibility in situ in a sheep with a fistula. The highest resistance at the rumen digestibility (46.60 ±3% in vitro and 46.30± 3% in situ) was observed in deposit-type capsules, being the alginate-guar gum formulation the most resistant to the release of the bioactive. It was evidenced that it is possible to use deposit-type capsules, formulated with biopolymers (alginate-xanthan gum and alginate-guar gum) to serve as a possible vehicle for bioactive agents and promoting the post-ruminal release in an ovine model for improvement in the quality of meat for the human consumption.
