Problems solved by technology

However, the steam distillation method is easy to cause the thermal decomposition of heat-sensitive compounds and the hydrolysis of easily hydrolyzed components due to the high operating temperature, which causes the aroma of essential oils to be unrealistic, and has low extraction rate of essential oils, poor quality of essential oils, and long distillation time. Defects such as high consumption
The pressing method has the disadvantages of low oil yield and short storage time of the finished product. Although the solvent extraction method has a high yield of essential oil, it has the disadvantages of residual organic solvents, toxicity, and long extraction time, which affect the quality of the essential oil and the subsequent cumbersome and complicated separation and drying operations.
Other ultrasonic-assisted extraction methods have problems such as high operation requirements, high cost, and limited production capacity.

Abstract

The invention belongs to the technical field of plant oil extraction, and in particular relates to plant extract oil as well as an extracting method and application of the plant extract oil. The extracting method of the plant extract oil comprises the following steps: crushing a raw material, and mixing the crushed raw material, water and plant oil according to a certain ratio so as to obtain mixed feed liquid; carrying out supercritical CO2 extraction on the mixed feed liquid to obtain extract liquor; carrying out oil-water separation on the extract liquor by using a high-speed centrifuge soas to obtain the plant extract oil. The extracting method of the plant extract oil has the characteristics of being free from pollution, mild in conditions, free from residue during extraction and high in separation efficiency, and can effectively improve the production efficiency and the product quality.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil extraction, and in particular relates to a plant extract oil, a method for extracting plant extract oil and an application thereof. Background technique [0002] Spice plants contain volatile aroma components, which can be extracted by chemical and physical methods, and are widely used in chemical industry, medicine, health care, cosmetics, food additives, detergents and other fields. Plant essential oil (or plant extract oil) is a kind of oily substance with volatile aroma produced in spice plants, which can be obtained from flowers, leaves, branches, roots, bark, gums, whole grass and fruits of spice plants. get. In addition to the pleasant aroma components, most of the plant essential oils have strong penetration, anti-oxidation, soothing nerves, scavenging free radicals, and softening the skin; some plant essential oils also have expectorant, cough, asthma, It has the functions of invi...
