Background: Stevia leaves a residual flavor at moment of being consumed, and its sweet taste remains little time, whereby, encapsulation is an option to mitigate these problems.Objective: Evaluate the double emulsion system followed by complex coacervation in stevia encapsulation.Methods: The effect of the concentration of the sweetener was determined (3.5; 5; 7.5 and 10% p/p) as well as the concentration of the wall material (2.5 and 5% p/p), on the morphology, capsules size, and encapsulation capacity.The double emulsion was prepared, the coacervate was formed, and then capsules were lyophilized.The morphology and capsule size were measured before and after lyophilization by optical microscopy.From Fourier´s infrared transformed spectrometry, encapsulation capacity was analyzed.Water activity and solubility were measured in lyophilized capsules.Results: Micro and nanocapsules (minimum size of 19.39 ± 0.74μm and 62.33 ± 6.65μm maximum) were obtained.Micrographs showed that the encapsulation technique used, allows obtaining dispersed stevia capsules and those of round and homogeneous morphology.The encapsulation capacity was 84.37 ± 4.04%.The minimum value of water activity was 0.49 ± 0.01 and 17.65 ± 0.91% of solubility.Conclusions: An increased in encapsulation capacity was obtained when the highest concentration of the wall material was used.The capsule diameter increased as the sweetener concentrations increased.The formulation to 5% (p/p) of stevia and 5% (p/p) in wall material was associated with better controlled release of the sweetener, which allows establishing subsequent applications in which the sweet taste is prolonged and the stevia bitter taste concealed.
