METHOD AND APPARATUS OF PROCESSING A FUNGAL MYCELIUM PRECURSOR MATERIAL INTO A MYCELIUM PRODUCT BY UTILISING SUPERCRITICAL FLUID

The invention relates to a method and apparatus of processing a mycelium object (30) into a mycelium product (MYP) by using a processing fluid in supercritical conditions, the mycelium object comprising hyphae cells, said hyphae cells having cell walls, the cell walls of said hyphae cells comprising natural polymer including chitin/chitosan polymer, the method of processing the mycelium object (30) including at least one of the following processes: a deacetylation process (DEP) a plastification process (PP) a dyeing process (DYP), a fat liquoring process (FLP) and a compacting process (COP), wherein at least one of the processes, the deacetylation process (DEP) the plastification process (PP) the dyeing process (DYP), the fat liquoring process (FLP) and the compacting process (COP), is performed by subjecting the mycelium object to an exposure of a reactive chemical agent (RCA) and a pressurized processing fluid (PF) in supercritical conditions.
