CO2 extraction method of tea seed oil

CO2 extraction method of tea seed oil

Wash the tea seeds to be extracted clean; dry the tea seeds to reduce the water content below 10%, then use a peeler to peel the shells to remove the tea seed shells;

Crush the hulled tea seeds and sieve through a 40-60 mesh sieve;

CO2 supercritical extraction, fluid extraction pressure is 35 M P a, extraction temperature is 40 ° C, CO 2 fluid flow is 700 ~ 800 L / h, extraction time is 3h, tea seed oil is obtained;

Extraction pressure is the main factor affecting the extraction efficiency of fats and oils. The solubility of fats and oils in CO2 increases with increasing pressure, but the increase in pressure will lead to a substantial increase in equipment investment. In addition, when the operating pressure is high, the color of the extracted fat becomes deeper, which has a certain effect on the quality of the oil.

When the pressure is 35 MPa, the extraction rate of tea seed oil is close to 90%, and the color of the fat is yellow, which meets the standards of edible oil.


The extraction temperature affects the solubility of fats in CO2. At low pressure, an increase in temperature will greatly reduce the density of the fluid, thereby reducing the solubility of the solute.

Under high pressure, the change in fluid density caused by temperature increase is small. At this time, the influence of the saturated vapor pressure of the solute with the increase of temperature plays a leading role, and the solubility of the solute increases. However, the high temperature hinders the diffusion process, squalene is easily decomposed or converted into other substances, and energy consumption is increased.

Extraction time is a parameter that has a lot to do with cost. Under certain conditions, as the extraction time increases, the oil content of the extract gradually decreases. When it is lower than a certain value, extending the extraction time will only increase the cost. It is necessary to choose a suitable extraction time.

Tea seed oil

Tea seeds contain many active substances, such as squalene, VE, phytosterols, etc., where the content of squalene in tea seed oil reaches 1% to 2%, but the angle of tea seed oil obtained by conventional refining methods The squalene content is only 30 ~ 40mg / kg.


CO2 Extraction Machine Buyer’s Guide

As you can imagine, not all supercritical CO2 extractors are made the same.
For more than 30 years, we have customized many CO2 extraction machines (Tabletop CO2 Extractor) for many companies and university laboratories (1 lb CO2 extractor). Because each customer’s CO2 extraction process requirements are different, there are almost no identical machines.

How many liters of CO2 extraction vessels are needed?

The first factor that determines the size of the CO2 extraction vessel is the daily working hours of the plant, which determines the daily extraction batch. The vessel size of the CO2 extractor depends on the biomass to be processed per day.

How many pressure is best for your CO2 extraction process requirements?

The choice of CO2 extraction pressure is a changing factor. If the extraction pressure is too high, the useless substances in the plant will be extracted, such as wax and chlorophyll. If the extraction pressure is too low, the extraction time will be increased.
