Stable and bioactive W/O/W emulsion loaded with “Pitanga” (Eugenia uniflora L.) leaf hydroethanolic extract

“Pitanga” leaf hydroethanolic extract (PLHE) presents high antioxidant and antimicrobial activities. The encapsulation of this in W/O/W double emulsions could protect its bioactive properties. objective research was to encapsulate PLHE the inner W phase a emulsion analyze emulsifiers concentrations ratios effects on droplet size physical stability. Moreover, rheological behavior, activities their more stable formulation investigated. For comparison purpose, also determined. Overall, stability were affected by concentration ratios. presented heterogeneous size, good non-Newtonian behavior. activities, which maintained after processing into emulsion. In conclusion, it possible produce active loaded with PLHE.
