Encapsulation is the process of protecting the active ingredients that is susceptible to environmental influences by using a coating. Red ginger oleoresin contains bioactive components that can be used as natural antioxidants, but sensitive to environmental influences. Chitosan-alginate nanoparticle is used as the coating, because it is safe for consumption and also stable. The purpose of this research was to determine the effect of the Tripolyphosphate (TPP) concentration against the emulsion droplet size and determine the encapsulation efficiency of red ginger oleoresin. Encapsulation method was done by mixing 2% chitosan solution with 1% acetic acid, 1% sodium alginate and 8 g of red ginger oleoresin. The mixture was stirred and added sodium tripolyphosphate (3.5, 4.5 and 5.5%, respectively), emulsion preparation process was done by adding tween 80 (3, 4 and 5%, respectively) and then stirred using homogenizer with a speed of 22,000 rpm, emulsions formed were analyzed using nano-particle analyzer. Emulsion formed was flowed on to the spray dryer inlet temperature of 180°C to form a powder encapsulation. Powder products were analyzed for determining encapsulation efficiency and morphology of red ginger oleoresin powder using Scanning Electron Microscopy (SEM). Based on the research results, the smallest droplet size of the emulsion was obtained at 481.5 nm and the largest encapsulation efficiency was as high as 70.59%.
