Now, the market demand for dry plant extracts is further increasing, and many manufacturers are also widely exporting them overseas. Due to the increase in demand, the development of this entire industry chain has been driven. With the research on plant extract extraction technology, many common extraction methods have been discovered. Sea buckthorn fruit oil is a pure natural nutritious plant essential oil extracted from the whole fruit of sea buckthorn by CO2 supercritical extraction. It has the unique aroma of sea buckthorn fruit. So, what is the principle of supercritical extraction of sea buckthorn fruit oil?

The principle of the separation process of supercritical CO2 flow and kohlrabi (SFE) is based on the relationship between the dissolving ability of supercritical fluid and its density, that is, the effect of pressure and temperature on the dissolving ability of the supercritical fluid. In the supercritical state, the supercritical fluid is contacted with the substance to be separated, so that it can selectively extract the components of polarity, boiling point, and molecular weight in turn.

Of course, the extract obtained corresponding to each pressure range cannot be single, but the conditions can be controlled to obtain a proportion of mixed components, and then the supercritical fluid can be turned into ordinary gas by means of decompression and temperature rise, and the substance to be extracted is The whole case or its original precipitation is to achieve the purpose of separation and purification, so the supercritical CO2 stream distillation process is composed of extraction and separation processes.

Sea buckthorn fruit oil is rich in unsaturated fatty acids, which can lower blood cholesterol, prevent atherosclerosis, and improve angina pectoris. In addition, sea buckthorn contains a lot of nutrients such as vitamin A and vitamin E, which can resist oxidation. Therefore, the relevant demand for sea buckthorn fruit oil in the market continues to rise.

As CO2 supercritical extraction is the extraction technology of sea buckthorn fruit oil, the market demand for its related mechanical equipment, such as CO2 supercritical extraction machines, naturally also grows.
