Abstract

Highlights: Cashew gum is an alternative in the encapsulation process by spray drying. Viscosity of the emulsion containing cashew gum was lower than Arabic gum. Modified starch and cashew gum reached higher encapsulation efficiency. Microparticles produced using cashew gum showed greater water adsorption. Oxidation process were less pronounced in cashew gum microparticles. Abstract: Evaluation of cashew gum compared to conventional materials was conducted regarding properties and oxidative stability of spray-dried fish oil. Emulsions produced with cashew gum showed lower viscosity when compared to Arabic gum. The particle size was larger (29.9 μm) when cashew gum was used, and the encapsulation efficiency reached 76%, similar to that of modified starch but higher than that for Arabic gum (60%). The oxidation process for the surface oil was conducted and a relative lower formation of oxidation compounds was observed for the cashew gum treatment. GAB model was chosen to describe the moisture adsorption isotherm behaviours. Microparticles produced using Arabic and cashew gums showed greater water adsorption when exposed to higher relative humidities. Microparticles produced using cashew gum were more hygroscopic however encapsulation efficiency were higher and surface oil oxidation were less pronounced. Cashew gum can be further explored as an encapuslant material for spray drying processes.
