Skittles and Apple Concentrate

Hi!

The ingredients in Skittles only lists "natural and artificial flavors," but nothing specific to that. I emailed them asking about apple concentrate, however they told me it was confidential information.

I have an apple allergy that started as an oral allergy, but is now a full-blown allergy. Eating apples makes me very sick and my throat swell, apple concentrate and pectin tend to make my throat extremely sore, and has gotten progressively worse over the years. It's been annoying finding out how many items have some form of apple, and loosing the ability to eat certain foods is frustrating.

Skittles make my throat crazy sore, and I just want to know if it has apple concentrate in the "natural and artificial flavors," or if I should pay attention to something else in the ingredients. Does anyone have any advice?
