Supercritical CO2 extraction of natural flavors

In the traditional extraction process of natural flavor, it is still an inevitable processing method that the flavor components are subjected to heat treatment.

Such as water vapor distillation and solvent extraction heating may cause some heat-sensitive or chemically unstable components in natural spices to be destroyed, thus changing the unique fragrance and flavor of natural spices.

The supercritical CO2 fluid extraction method can carry out the entire separation process at room temperature, and the CO2 is non-toxic and has no residual phenomenon, so it is particularly suitable for the separation and purification of unstable natural products and physiologically active substances, which is suitable for the production of fragrances that are closer to natural fragrance. The trend of processed products.

The supercritical CO2 fluid extraction method has attracted much attention because of the possibility of preparing almost perfect “natural” fragrances.

It has become one of the most effective technological methods to obtain high-quality essential oil products.
