Firstly, CS-stearic acid (SA) and CS-oleic acid (OA) nanogels were prepared. The results of IR spectra showed a successful binding between CS and fatty acids. In addition, the D50 of CS-SA nanogels was lower than that of CS-OA. Then, hempseed oil-in-water Pickering emulsions were stabilized by CS-based particles/maltodextrin (MD) and dried by the spray dryer equipped with the electrostatic collector. The results showed that droplet size of reconstituted emulsion from oil powder with CS-SA/MD coating (886.4±146.4) was significantly (p≤0.05) less than that of emulsion with CS-OA/MD (1415.8±130.0). SEM images also showed that hempseed oil encapsulated with CS-SA/MD had more sphericity, porosity, and crystallinity compared to that encapsulated by CS-OA/MD. Moreover, hempseed oil encapsulated with CS-OA/MD had higher oxidative stability that encapsulated by CS-SA/MD.
