Solid/liquid extraction with a solvent comprising between 5 and 8 carbon atoms and 1 or 2 oxygen atoms

摘要

The present invention relates to a process for the solid/liquid extraction of a natural extract contained in at least one vegetable solid or micro-organism comprising at least the following steps:
solid/liquid extraction of at least one vegetable solid or micro-organism by a first solvent system comprising a solvent content chosen from the solvents comprising between 5 and 8 carbon atoms and one or two oxygen atoms in ether function, or ketone function, or ester function form, of at least 50% by volume in relation to the total volume of the first solvent system,retrieval of a natural extract, notably comprising or consisting of an oil or a butter, particularly enriched with unsaponifiable.

1. A process for solid/liquid extraction of a natural extract contained in at least one vegetable solid or micro-organism, comprising at least the following steps:
solid/liquid extraction of at least one vegetable solid or micro-organism by a first solvent system comprising a solvent content selected from solvents comprising between 5 and 8 carbon atoms and one or two oxygen atoms in ether function, or ketone function, or ester function form, of at least 50% by volume in relation to the total volume of the first solvent system, retrieving a natural extract comprising an oil or a butter,wherein the solvent comprising between 5 and 8 carbon atoms and one or two oxygen atoms is selected from methylketones, propionates, propyl ethers, and mixtures thereof.
