【 摘 要 】

Vitamin E from palm fatty acid distillate (PFAD) has been encapsulated using spray drying method with gum acacia (GA) and mixed of galactomannan from Arenga pinnata (GAP) with GA as encapsulating agent. Composite films with thickness vary from 0.542-0.779 mm were prepared by incorporating Vitamin E onto matrix of GA (7 g) with various concentration of GAP (0.1; 0.2; 0.3 and 0.4 g). The film obtained from 0.2 g GAP and 1.3 g Vitamin E showed better compatibility and have viscosity similar with standard (ISO 9001:2008 and ISO 22000:2005). That composition was used for spray drying method rendering micro-particle size 11 m and the particle had spherical shape. Although the increment of GAP decreasing moisture content and the particle size from 16 m to 11 m, the yield of microcapsule, encapsulation efficiency, the amount of Vitamin E absorbed and oxidation stability of Vitamin E were increased.
