Lyofiltterderivatit
Lyofiltterderivatit, a term that appears to be a portmanteau, likely refers to substances or products derived from a lyophilization process that involves filtration. Lyophilization, commonly known as freeze-drying, is a dehydration technique used to preserve perishable materials or make them more convenient for transport. It involves freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase. Filtration is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but not the solid.
Therefore, lyofiltterderivatit would suggest materials that have undergone both a filtration step and a subsequent lyophilization.
