What is a meaning of glow food?

Bioluminescence is the production and emission of light by a living organism. Some examples of bioluminescent organisms are fireflies, deep sea fish, and fungi. Glow food is food that has been genetically modified to produce light. Researchers at the University of Wisconsin-Madison have developed a line of genetically engineered mice that produce a protein that emits light when it is exposed to certain chemicals. The researchers have used this protein to create glow food, including cheese, pickles, and ice cream. Glow food has the potential to be used for a variety of applications, such as detecting food spoilage or creating more visually appealing food products.
