Conteúdo: | The objective of this work was to evaluate the influence of the homogenization method, ultrasound or rotorstator, on the properties of emulsions formed with chia oil (Salvia hispanica L.) and on the stability of this powder oil. Microencapsulation was performed by spray drying, using as a wall material a mixture of maltodextrin 10DE, maltodextrin 20DE, whey protein isolate and gum arabic (40/40/15/5). The characterization of the microparticles was performed by moisture, particle size, surface oil, encapsulated oil, encapsulation efficiency, morphology, lipid oxidation and oxidative stability. The use of ultrasound promoted a significant reduction in droplet size (4.62 to 0.48 ?m) and a considerable increase in encapsulation efficiency (42 to 96%). In this way, it was possible to obtain a microparticle of chia oil with concentration of oil of industrial interest (30% w/w) with high encapsulation efficiency and good oxidative stability, using the green ultrasonic technology for the oil homogenization stage.
