Camellia essential oil extracting method

Abstract

The extraction method of camellia essential oil is characterized in that the method comprises the following steps: (1) adding edible salt by an amount of 5 to 15% weight of fresh camellias, kneading, adding into a container, compressing, fixing fragrance at room temperature for 1 to 7 days, adding No.4 solvent (butane or mixture of butane and propane) into the camellias after fragrance fixation at normal temperature and under a certain pressure, extracting to obtain camellia liquid, and distilling by conventional method to obtain the camellia essential oil; or (2) drying the fresh camellias under the sun or in an oven, extracting the dried camellias with carbon dioxide and methanol or ethanol at a weight ratio of 1:(30 to 50):(10 to 40) under a pressure of 30 to 50 MPa, and separating the extractive liquid to obtain the camellia essential oil. The invention provides the method for extracting the camellia essential oil from the camellias by using simple process and less production equipment to fill the blank in camellia utilization, and develops a path for deep development and utilization of the camellias.

Description

technical field [0001] The invention belongs to the field of biochemistry, and in particular relates to a method for extracting camellia essential oil by using camellia as raw material. Background technique [0002] Camellia, also known as Camellia, is a plant of the genus Camellia in the family Theaceae. Camellia is the essence of the camellia tree.
