摘要：
A pomelo peel essential oil extraction method by peel icing and breaking. The method comprises: first selecting fresh pomelos, using a peeling machine to peel outermost cell layers of the fresh pomelos, and collecting the outer peel which is 1.5 mm to 2.5 mm thick； slowly icing the pomelo peel cell layers at -15°C to -30°C to form ice； using a breaker to break the pomelo peel ice； thawing the broken ice, and then using a screw extrusion press for pressing to obtain a pressed mixed liquid； adding 3 to 4 mass% of salt into the pressed mixed liquid, allowing the liquid to stand and layer under reduced pressure to obtain an oil-water mixed liquid； and distilling the mixed liquid under reduced pressure, collecting distillate to obtain the oil-water mixed liquid, allowing the oil-water mixed liquid to layer naturally, and removing the water layer to obtain the pomelo peel essential oil.
