Vending machine patrons that pay close attention to the ingredients of their favorite confections may have noticed that treats with natural coloring are not available in blue or green. The reason for this, is that until recently, the FDA had not approved a natural color additive that created these desired shades. Now, the FDA has approved spirulina extract as a source of blue color in candy and gum.
This is big news for gum and candy manufacturers who until now had to use FD&C Blue #1 ("brilliant blue") which is an artificial ingredient for blue coloring. US manufacturers had been left behind as spirulina extract has been previously approved in other markets. The benefit to this is that there is now a history of spirulina use and testing that the FDA and manufacturers can take advantage of.
If you have been looking for a vending machine for sale, you will most likely know what kinds of snacks and candies are popular in vending machines. Vending.com's machines are very frequently stocked with chewing gum, and blue and green coloring will be a very popular choice for manufacturers.
