Consumers sour on milk exposed to LED light | Cornell Chronicle

Got LED light? Display cases and grocery stores increasingly do, and that’s bad news for milk drinkers.

Cornell researchers in the Department of Food Science found exposure to light-emitting diode (LED) sources for even a few hours degrades the perceived quality of milk more so than the microbial content that naturally accumulates over time. Their study determined milk remained at high-quality for two weeks when shielded from LED exposure, and consumers overwhelmingly preferred the older, shielded milk over fresh milk stored in a typical container that had been exposed to LED light for as little as four hours.
