GRAS Food Dyes

The industry of processed foods and food additives has grown immensely. The FDA regulates these additives in order to deem them safe or unsafe. Those additives surpassing regulations are entitled "GRAS" by the FDA. Gras is an acronym for "generally regarded as safe." "Under sections 201 and 409 of the Federal Food, Drug, and Cosmetic Act any substance that is intentionally added to food is a food additive…generally recognized among qualified experts as having been shown to be adequately safe…" There are currently 7 synthetic food dyes approved and recognized by the Food, Drug, and Cosmetic Act. These food dyes serve no purpose but to be aesthetically pleasing. More specifically these food dyes are used for; coloring loss, "making food more fun", and enhancing natural color. At what cost are these foods made "more fun?"

3 questions!!!

*This was saved in my drafts but not published* -_-
Lately we have done the usual. Online homework, notes, lab…… I have learned about much about electron configuration and light emission! We've also learned a new concept called PES. I plan to do much work in reviewing and trying hard in order to understand the multitude of concepts being thrown at us. :)
