The present disclosure employs two principles:The first principle consists of producing a great and sudden decompression which causes a great and sudden expansion of the gases present in the cytoplasmic and organelle liquids of the contaminative organisms, thereby causing the death of the contaminative organisms. This process can be accomplished at low temperatures near the freezing points of the liquids to be treated, thereby preserving all the molecules of the nutrients that get lost with the higher temperature used in the pasteurization process.The second principle consists of subjecting the liquids to be treated, conformed in droplets or fine sprays, to great linear or rotatory accelerations, or both, which can reach up to 1,000 times the gravitational acceleration on Earths surface, through frontal, tangential or oblique shocks. These shocks have lethal effects on the cell membranes, organelles and, mainly, cytoskeleton and organelle architecture of the contaminative organism cells.
