The hydrothermal treatment is based on placing the crude residual plant material in contact with hot water in a closed reactor, comprising the following steps: a) placing the material to be treated in contact with water in a closed reactor, and adjusting the solid/liquid ratio so that it ranges from 1/5 to 1/15 (w/v): b) stirring; c) heating to a temperature between 180 and 240° C., and at a pressure so that the water is maintained in liquid phase; d) constantly stirring the mixture for a time period between 4 and 30 minutes; and e) cooling the reactor to approximately 40° C., unloading the mixture, filtering and recovering the liquid fraction.
Process to extract phenolic compounds from a crude residual plant material using a hydrothermal treatment, characterized in that it places said crude residual plant material in contact with hot water in a closed reactor, at a temperature between 180° C. and 240° C., and a pressure so that the water is maintained in liquid phase.
