Abrégé
(EN)
The present invention relates to a antisolvent solidification process wherein a liquid medium comprising at least one organic or inorganic compound which is to be solidified is forced through a membrane into one or more antisolvents, or wherein one or more antisolvents are forced through a membrane into a liquid medium comprising at least one organic or inorganic compound which is to be solidified, yielding a composition comprising solid particles comprising said organic and/or inorganic compound(s).
