1) It can be extracted at near normal temperature without destroying biological active substances, especially suitable for the separation, extraction of heat-sensitive and easily oxidized substances.
2) The extract has no residual solvent, so it is called "100% natural".
3) Extraction process parameters are easy to adjust and control, and the products have high yield.
4) Little extraction procedure, simple process, high efficiency and low energy consumption.
5) CO2 is cheap and easy to use, non-toxic and tasteless, not producing "three wastes", pollution-free and "environmentally friendly".
6) Well selectivity. Can extract out requested component according to control pressure and temperature.
7) Low operating temperature. Operation often happen under room temperature, which is much better for Heat-sensitive Materials. Because during extraction process, it has avoid “when oxygen oxygenation” and “when light reaction”, product can keep its natural tastes.
8) Finish within one step, CO2 won’t be left on the products.
9) CO2 is a kind gas of non-poisonous, tasteless, inflammable, cheap and can be cycle use.
