Many people like the taste of raw – as in unpasteurized – milk. The problem, of course, is that germs may infect raw milk, so food safety regulations require that commercial producers heat-treat their milk. But food scientists at Louisiana State University think they’ve stumbled onto a tastier way to sterilize milk. They bombard it with sound waves.
