A method of ice-crystal wall-breaking extraction of the pomelo peel essencial oil, including: first selecting a fresh pomelo, peeling off the outmost oil cell layer with a peeler, and collecting the cortex that is 1.5-2.5 mm thick; slowly freezing the pomelo peel oil cell layer at 15 C. to 30 C. to form ice crystal; breaking the pomelo peel ice crystal with a breaker; thawing the broken ice crystal, and then squeezing with a screw squeezer to obtain a squeezed mixed liquid; adding 3-4% by mass of the table salt to the squeezed mixed liquid, and standing to stratify at reduced pressure, thereby obtaining an oil-water mixture; distilling the mixed liquid at reduced pressure, and collecting the distillate to obtain an oil-water mixture that undergoes natural stratification; discarding the water layer, thereby obtaining the pomelo peel essential oil.
