Title (EN) PROCESS FOR THE REMOVAL OF CONTAMINATION FROM A RAW MATERIAL
(FR) PROCÉDÉ DE DÉCONTAMINATION D'UNE MATIÈRE PREMIÈRE
Abstract:
(EN) The present invention relates to a process for the removal of contamination from a raw material comprising a desirable material, such as chitin and/or chitosan. The process comprises mixing a raw material with a liquid, wherein the raw material comprises at least one contaminant and at least one desirable material, and wherein the at least one desirable material is capable of absorbing the liquid; and allowing the at least one contaminant and at least one desirable material to separate in a separation container.
(FR) La présente invention concerne un procédé de décontamination d'une matière première comportant un matériau recherché, comme la chitine et/ou le chitosane. Ledit procédé comprend les étapes consistant à mélanger une matière première avec un liquide, ladite matière première comprenant au moins un contaminant et au moins un matériau recherché et ledit ou lesdits matériaux recherchés étant capables d'absorber le liquide ; et à laisser ledit ou lesdits contaminants et ledit ou lesdits matériaux recherchés se séparer dans une cuve de séparation.
