Abstract

The invention discloses an extraction method of rosa rugosa essential oil, which comprises the steps: cutting up or pulping raw material rosa rugosa to 5-30 meshes, evenly spraying 0.01-0.1% of bio-enzyme solution for enzymolysis reaction, placing the mixture into an extraction kettle, transferring CO2 into the extraction kettle; regulating the temperature of the extraction kettle into be 30-55 DEG C, and the extraction pressure being 20-40 Mpa. After the extract obtained by separation in a three-level decompression separation mode is extracted for 1.0-4.0h, the extract is sent out from the bottom of a secondary separation kettle to obtain the rosa rugosa essential oil. The extraction method uses the supercritical CO2 for extracting the plant essential oil in the raw material rosa rugosa in the condition of approaching the normal temperature, and has simple and convenient operation and high yield. The essential oil extracted from the rosa rugosa can be used for preparing daily necessities, cosmetics, medicines, foods and the like and has wide application range.

Description

technical field [0001] The invention relates to a method for extracting natural plant essential oil, more specifically, the present invention relates to a method for extracting the essential oil of Osmanthus fragrans. Background technique [0002] The extraction of natural spice essential oils is often carried out by water distillation or solvent extraction. Such processing of natural fragrances often causes changes in components, thereby changing the entire fragrance profile, and often loses the top fragrance, the product loses its freshness, and pollution from solvent residues is unavoidable. Supercritical CO 2 Extraction makes up for the deficiencies of the above-mentioned technologies. Supercritical CO 2 Extraction technology is based on CO in a supercritical state 2 New separation techniques on fluids with special solubility effects on organics. This technology has unique advantages for the separation of large molecular weight, heat-sensitive or chemically unstable...
