Processing process of Chinese prickly ash oil

Abstract

The invention provides a processing process of Chinese prickly ash oil. The process includes the three steps of raw material preparing, Chinese prickly ash oil extracting and finished product packaging. The raw material preparing step includes the substep of drying fresh Chinese prickly ash in the sun. The Chinese prickly ash oil extracting step includes the substeps of heating vegetable oil, cooling the vegetable oil, soaking the Chinese prickly ash in the vegetable oil, and conducting quick cooling and centrifugal filtering. The Chinese prickly ash oil prepared through the steps is golden yellow in color and luster and pleasant in fragrance; through the improvement of the process, peculiar smell in finished product oil is eliminated, and meanwhile the volatilization or loss of volatile oil, xanthoxylin and other volatile substances or easy-to-loss substances in Chinese prickly ash is avoided to the maximum extent. The process is simple in process structure and suitable for large-scale production.
