polyunsaturated fatty acids, storage stability, appropriate ratio, hydrogen bonds


Our study deals with the protective effect of gelatin-acacia as a wall material on Elaeagnus mollis oil (EMO), the core material with over 45% polyunsaturated fatty acids. We found that 2.0% of the gelatin-acacia complex was an ideal concentration for facilitating the microencapsulation of EMO. The ideal ratio of EMO/wall materials would be 1:1. As a result, the microencapsulated EMO successfully underwent the spray-drying treatment because of close hydrogen bonding between EMO and the gelatin-acacia complex. Moreover, no spoilage was observed for the heated EMO microcapsules during storage.
