Ah dreaded chemicals!  They have made their way into so many product, including food and these scientists have come up with a potential new way to preserve food…using light!

Scientists from the National University of Singapore (NUS) have discovered that blue light emitting diodes (LEDs) have strong antibacterial effect on major foodborne pathogens which paves the way to use blue LEDs as a chemical-free food preservation method

Acidic foods such as fresh-cut fruits and ready-to-eat meat can be preserved under blue LEDs in combination with chilling temperatures without requiring further chemical treatments that are commonly needed for food preservation.

The findings have been published in the Food Microbiology journal.

Let’s find out more on how this actually works and check out a cool video on page 2
