Abstract

The aim of this research is to protect the omega-3, omega-6, and omega-6 PUFAs in candlenut oil through microencapsulation by spray-drying method. Cold expeller press machine was used for the candlenut oil extraction to maintain the omega fatty acids content. Four wall materials used were HPMC, Alginate, β-cyclodextrin, and gum arabic with the wall materials to oil ratio were 3:2, 1:1, and 2:3 respectively for the microencapsulation. Initially, viscosity of the microencapsulated candlenut oil emulsion was measured. Then, the emulsions were spray-dried to obtain the microencapsulated candlenut oil powder. Moisture content, wettability, microencapsulation efficiency (ME), and peroxide value (PV) for analysis were evaluated as the powder parameters. The data obtained showed that microencapsulation through spray-drying process was successful in protecting the candlenut oil against oxidation. Higher wall materials concentrations lead to higher viscosity and higher ME, except for alginate formulation with 3:2 ratio (A1). Thus, in terms of ME, β-cyclodextrin formulation with 3:2 ratio (C1) showed the best performance with 80.98%, while in terms of peroxide values, gum arabic formulation with 3:2 ratio (G1) showed the best performance with 0.69 meq/kg.
