Document Summary

Synthetic colors are sometimes known as coal tar dyes because they were extracted from coal tar. Means that its manufacturing process has been checked and it is certified that it will gi(cid:448)e (cid:449)hat it(cid:859)s supposed to gi(cid:448)e. Was used to color the skin of oranges (it had to be mentioned on the label) Some oranges are green because of the high chlorophyll content. People do (cid:374)ot like to see (cid:858)(cid:859)color added(cid:859)(cid:859) o(cid:374) food. American physician, came up with the theory that food dyes and salicylate were associated with hyperactivity in children. --many studies have come up with different conclusions regarding that.
