FIELD: fat and oil industry.
SUBSTANCE: invention relates to oil extraction from vegetable sources, in particular, palm oil. Method of extracting oil from a premacerated oil-bearing material comprises following steps: a) subjecting premacerated oil-bearing material to at least one sonication step, wherein at least one plate transducer emitting a frequency of at least 400 kHz is employed to create a standing wave in macerated material; b) separating components to form a first oil phase and a retained material phase; c) removing first oil phase; d) optionally subjecting retained material phase to at least a second sonication step and removing a second oil phase. Oil obtained by this method.
EFFECT: invention increases output of oil.
