Abstract

The invention discloses a preparation method of a high-purity citrus peel essential oil. The method comprises selecting fresh citrus peel as the raw material, cutting the citrus peel into pieces at room temperature, and then soaking the citrus peel pieces into soaking fluid; taking the soaked citrus peel out of the soaking fluid and draining off liquid; squeezing the soaked citrus peel through a screw type squeezer obtain an oil-water mixture containing pigments, pectin and citrus scraps; centrifugally separating the oil-water mixture through a centrifugal separator, extracting an upper oil layer, and filtering the upper oil layer after wexes settle to obtain coarse citrus peel essential oil; refining the coarse citrus peel essential oil through a molecular distillation stepwise method, and collecting distillation residues II which are mainly composed of D-limonene and gamma-terpinolene. By means of the squeezing method and the molecular distillation technology, the preparation method of the high-purity citrus peel essential oil can effective protect thermosensitive components in the essential oil and produce the citrus peel essential oil, which is clear in color, pure and rich in fragrance and prominent in characteristic flavor, under the condition of low temperature and no organic solvent.
