Abstract
Animal or plant derived materials are prepared for extraction of desired substances therefrom by grinding said materials at or below their Brittleness Temperature. This treatment allows fracture of the materials into small particles with high surface area to volume, as well as high volume to mass ratios, and disrupts membranes of tissues, organs, cells or organelles which would otherwise prevent or limit separation of desired biomolecules.
Claims22
Method for obtaining a desired substance from animal material comprising freezing said animal material to its Brittleness Temperature with liquified inert gas, cryogrinding said material into a cryopowder, wherein the temperature at which grinding takes place is or is maintained at no higher than said Brittleness Temperature, and extracting said substance from said cryopowdered animal material by means of a process selected from the group consisting of aqueous solvent extraction, organic solvent extraction, supercritical extraction and thermal extraction.
