Display Case LED Lighting Negatively Impacts Milk Quality

Researchers have found that LED lights now being used in more display cases may have a negative impact on milk quality.  As the industry moves to LED lighting for energy savings, milk producers will need to look at packaging materials that will prevent the specific wavelengths that can cause deterioration.

In the release it states that "Riboflavin and other photosensitive components in milk are activated when struck by light energy, releasing a cascade of electrons that can degrade proteins and oxidize fats........LED lighting produces a pattern of wavelength that differs from the fluorescent bulbs that have been used to illuminate display cases. LEDs typically emit in the blue spectrum, around 460 nanometers, and produces a broader emission peak than fluorescents. That peak in LED light is near the narrow band where riboflavin absorbs light, a fact the researchers surmise could be selectively destroying the nutrient and damaging the perceived quality of the milk."

So is LED lighting having an impact on other food products?
