Exploding Beef
Research scientists at USDA’s Agricultural Research Service in
Maryland had been requested to explore a theory that came from a
retired nuclear weapons designer. The theory suggested that shock
waves unleashed by an explosive set off in water could tenderize a
piece of meat submerged in water.
To explore the concept, they put steel in the bottom of trashcans.
Then they suspended meat in water inside the trashcans, buried the
trashcans, and detonated explosives.
The shock waves created by the explosion travel through anything
that is an acoustic match with the water, and tear anything that is
not an acoustical match. Beef is about 75% water, and the muscle
tissue and fat are not. Thus, the hydrodynamic pressure tenderizes
the beef.
Along the way, scientists discovered that applying hydrodynamic
pressure to the beef was not only tenderizing the meat, but also
eliminating harmful bacteria by 40 to 60%. This discovery was an
added bonus!
Dr. Solomon — the exploding
beef expert.
Dr. Solomon demonstrates
the experiment.
