Food Risk Assessment: Malachite Green

Biomedical Engineering and Chemical Engineering Professors Bob Tilton and Todd Przybycien recently co-authored a paper with Ph.D. students Brittany Nordmark and Toni Bechtel, and alumnus John Riley, further refining a process that could soon help provide clean water to many in water-scarce regions. The process, created by Tilton’s former student and co-author Stephanie Velegol, uses sand and plant materials readily available in many developing nations to create a cheap and effective water filtration medium, termed “f-sand.”

Waste oil from orange, tea tree and eucalyptus essential oil production mixed with diesel provides a sweet-smelling biofuel blend with comparable performance to diesel-only fuel.

From vine to wine, grapes undergo a remarkable transformation. But sometimes this makeover results in vino that doesn’t taste quite right. In a new study scientists report that they have found a way to use tiny magnetic particles to remove off-tasting substances in cabernet sauvignon without altering its desired bouquet.
