Several product developers are switching to LED lights for their long lasting benefits and a clean, bright hue. In most instances, LEDs have become the preferred lighting source over other types, such as fluorescent, but a new study suggests the refrigerator may not be one of those instances.

A recent study found LED lights can actually degrade the taste of milk faster than fluorescent lights. After exposing skim and 2% milk to various lighting sources and having 304 participants taste them, researchers found the majority of participants had a distaste for LED-lit milk. Scientists say the riboflavin, a vitamin found in most dairy products, actually absorbs LED light and gives milk a strange taste.

The quick-fix solution is to keep dairy in opaque containers that block the LED light, says Martin Wiedman, a professor of food safety at Cornell University.
