Microencapsulation is presented as an alternative to delay the oxidation of polyunsaturated fatty acids and thus increase the shelf life. The literature indicates spray drying as the most widely used method for encapsulating oils. However, it has some disadvantages, such as the use of high temperatures increases the oxidation of polyunsaturated fatty acids. In this context, spray drying makes it possible to convert a liquid food into a solid. The objective of this study was to optimize the spray drying conditions for sacha inchi oil (Plukenetia volubilis L.) using the response surface methodology. The results indicated that the response corresponding to the response surface model was sufficient to describe and predict the encapsulation efficiency (EE). The effect of the inlet air temperature (160-180 °C) and the combination of GA:INU was evaluated. The microparticles obtained under opti...

This study aimed to formulate burgers made from three Amazonian fish species: pacu (Pyaractus brachypomus), boquichico (Prochilodus nigricans), and bujurqui (Chaetobranchus flavescens), focusing on sodium reduction and fortification with fish oil microparticles (FOM) rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The proximal composition, sodium and calcium content, instrumental texture profile, fatty acid profile, sensory profile, and overall liking were evaluated. Differences in proximal composition and fatty acid profiles between the fillets were reflected in the burgers. Fortification with FOM increased EPA and DHA in the burgers; thus, they can be considered “high in omega-3 fatty acids” and reduced the n-6/n-3 ratio below 4. There were sensory attributes that could be related to lipid oxidation but reduced overall liking for less than 10% of consumers. Neve...
