New approach in process intensification based on subcritical water, as green solvent, in propolis oil in water nanoemulsion preparation

Subcritical water was used to provide propolis oil in water (O/W) nanoemulsions. To monitor and detect the main bioactive compounds of the prepared propolis extract, gas chromatography demonstrated that there were 47 bioactive materials in the propolis extract, among which pinostrobin chalcone and p...
