Abstract

The invention relates to a method for extracting jasmine essential oil. The method comprises the following steps: (1) flower picking, picking fresh jasmine in an air-conditioned room, uniformly spreading, culturing the flowers to 22:00 to 24:00 in order that the jasmine is in early puberty for later use; (2) fragrance pumping, placing the jasmine which is in the early puberty into a jasmine fragrance extraction device, adsorbing the jasmine fragrance through an active carbon adsorbent in the jasmine fragrance extraction device for later use; (3) extracting, placing the active carbon adsorbentby which the jasmine fragrance is adsorbed into an extraction tank, inflating the CO2 into the extraction tank for performing CO2 ultra-critical extraction to obtain the jasmine essential oil for later use; (4) heating the jasmine essential oil prepared in the step (3) to the temperature of 100 DEG C or more, evaporating water vapor to obtain the jasmine essential oil. The jasmine essential oil has the characteristics of good effect, high yield, high purity and the like.

Description

technical field [0001] The invention relates to the technical field of flower aroma extraction, in particular to a method for extracting jasmine essential oil. Background technique [0002] The country's largest jasmine base is located in Heng County, Nanning City, Guangxi.
