Fuente: WIPO "essential oil or extracts" The present disclosure provides a flower essential oil extraction method. The flower essential oil extraction method includes (a) placing flowers in a high-pressure treatment tank; (b) introducing pressurized liquid medium into the high-pressure-treatment tank so as to reach a predetermined pressure, wherein the pressure is maintained for a predetermined period of time at a predetermined temperature, then the pressure is reduced to atmospheric pressure; and (c) placing the flowers subjected to high-pressure treatment in an extraction tank, wherein flowers are extracted with a low-polarity solvent to obtain an extract. By using the flower essential oil extraction method of the present disclosure, the flowers do not need to be subjected to a dehydration process, thus the energy cost is reduced, and more ingredients can be retained. Additionally, the flower essential oil extraction method of the present disclosure can reduce the energy consumption of drying and extraction so as to effectively reduce the manufacturing costs, thereby improving the industry competitiveness.
