Northeasern looks like a great school, I don't really know much about it, but the reviews and scores of it on princetonreview.com look great. In
undergrad, I was actually a molecular biology major with a minor in English literature. Right now, I'm in my second year of medical school.
As far as the categorization of natural and artificial flavors, the FDA cites is as follows:
"The term artificial flavor or artificial flavoring means any substance, the function of which is to impart flavor, which is not derived from a
spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, fish, poultry,
eggs, dairy products, or fermentation products thereof. Artificial flavor includes the substances listed in 172.515(b) and 582.60 of this chapter
except where these are derived from natural sources."
They define natural flavors as follows:
"The term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any
product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or
vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation
products thereof, whose significant function in food is flavoring rather than nutritional. Natural flavors, include the natural essence or extractives
obtained from plants listed in subpart A of part 582 of this chapter, and the substances listed in 172.510 of this chapter."
