Light, Another Enemy of Food Storage

Light is the least understood enemy of food storage.  Exposure to light can cause foods to spoil faster.  Both natural and artificial light can cause photodegradation, according to the Department of Food Science and Human Nutrition at Clemson University.  Exposure to sunlight, fluorescent light or incandescent light can cause photodegradation.

The light sensitivity of a food depends on many factors including the:

  • light source strength and type of light that it emits;
  • distance of the light source from the food;
  • length of exposure;
