Abstarct: The main objectives of this study were to encapsulate hempseed oil using different chitosan nanogels and to investigate the morphology, particle size and oxidative stability of the powders produced. In the first stage, chitosan-palmitic acid, chitosan-stearic acid and chitosan-oleic acid nanogels were prepared. The results of the ATR spectra showed a successful binding between chitosan and palmitic, stearic and oleic fatty acids. Also, the particle size and zeta potential of chitosan-palmitic, chitosan-stearic and chitosan-oleic nanogels were 395.2, 462.2 and 475.7 nm and 31.8, 43.4 and 47.8 mV, respectively. These results showed that with increasing the chain length as well as the unsaturation of the fatty acid, the particle size and the zeta potential of the nanogel increased. Then, Hempseed oil was encapsulated with spray drying method using different nanogels baxsed on chitosan and maltodextrin with equal weight ratios. Scanning electron microscopy images showed the size of the dried powders ranged from 139 nm to 455.3 μm. The results of X-ray diffraction analysis revealed that hempseed oil encapsulated with chitosan-palmitic acid nanogel wall material with maltodextrin had better crystallinity compared to other walls. The results of differential scanning calorimetric analysis showed that the oxidative stability of hempseed oil increased with the encapsulation. Also, hempseed oil encapsulated with chitosan-stearic acid nanogel/maltodextrin had the highest oxidative stability. Color characteristics of encapsulated powders were determined by L* values (from 61.89 61±11.62 to 71.46± 11.57), a*(from -1.44±0.80 to 0.08±0.67) and b*(from 3.05 ± 0.65 to 7.54±1.09) which showed that different wall materials were able to cover the greenish color of hemp seed oil acceptably.
