The yield of crude carrot oil extracted with TSE and SFE (SC-CO2 without canola oil addition) under different conditions was presented in Fig. 1. The crude oil yields of SFE were 1.83–2.69 g/100 g dry carrot, which were similar to that obtained with TSE (2.46 g/100 g dry carrot). Theoretically, the solubility of carotenoids in SC-CO2 increases with pressure at constant temperature. Because of the cross-over of solubility isotherms, in general, the solubility decreases with temperature at pressures below the cross-over pressure and increases with temperature at higher pressures. However, the values reported in Fig. 1 were the total amount of extract collected after 4 h, which may not correspond to solubility depending on the shape of the extraction curve, since it may have already reached the diffusion-controlled region.
