Microencapsulated fish oil powder by spray drying using combination of wall materials in Kasetsart University, Bangkok

Oil is a source of saturated fatty acids commonly referred as omega-3, in particular EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) and has been recognized major health component, being used in many key ways as body supplements and heart organs in particular. The omega-3 content of fish oil is highly oxidizing due to exposure to oxygen. One way to be treated is to do microcapsule storage using a spray dryer. Applications of materials coated-based fish oil for the microcosulation are generally varied. The purpose of this internship is to figure out the microencapsulated of fish oil by spray dry using combination of wall materials. This internship was held in Department of Fishery Product, Faculty of Fisheries, Kasetsart University, on January 1th until January 30th, 2020. The process is done through of three stages of pretreatmend, spray dry, and testing. Pretreatmend process includes to making fish oil emulsion with gum arabic, maltodextrin, and whey proteins. Spray dry includes microencapsulated preparation using spray dryer machine. The testing process is done by some parameters like yield, color, water content, oil content, and water activity.
