Titanium can sometimes be detected by metal detectors. Whether a particular metal detector can detect titanium depends on the sensitivity and discrimination factors of that metal detector.

An inorganic chemical, titanium dioxide is used as a dye to help products achieve a certain appearance, including whitening a product. Some experts and publications have described it as being akin to a paint primer that's used before the color is added to food in order to give products a uniform shine. Its presence is common in many items beyond Skittles including coffee creamers, cake mixes, and chewing gum. It's also used for pigment and in cosmetics manufacturing.

So if you’re worried about titanium dioxide, don’t be! With current research and industry recommendations, titanium dioxide is a safe food additive. And if you want to avoid it, that’s ok too! Just don’t expect certain foods to be so white, smooth, and bright.
