Sumario:[EN] The objective of this research was to microencapsulating the pumpkin seed oil (PSO) by the spray dryer and also investigating the effects of some process conditions on physicochemical properties of PSO microparticles. Inlet drying air temperature (140-180 ͦC), aspirator rate (55-75%), and peristaltic pump rate (5-15%) effects were studied. Moisture content (%W.b.), Microencapsulation Efficiency (MEE, %) and Peroxide value (POV, meq/kg sample) considered as model responses. Consequently, the ideal drying state for microencapsulation of PSO as a result of optimizing by Response Surface Methodology (RSM) determined with the aim of minimizing the Moisture content and POV and maximizing the MEE.
