Extraction of Oil from Rosehip Seed: Kinetics, Thermodynamics, and Optimization
Rosehip (Rosa caninaL.) oil (RSO) was recovered from waste rosehip seeds by cold pressing as well as maceration and Soxhlet extraction usingn-hexane. The influence of the extraction temperature, the solvent-to-seed ratio (SSR), and the extraction time on RSO yield was examined for the maceration process. The extraction technique did not influence the fatty acid profile of the RSO. All process factors had a significant effect on the oil yield. The kinetics was described using the model involving instantaneous washing followed by diffusion. The RSO maceration was spontaneous, endothermic, and irreversible.
