Here is a pretty good way to buy vanilla I just googled it rather than mislead. Hope it helps.
"How do you know if it's pure vanilla? There are a few tip-offs:
* Is it amber colored, dark and murky, or clear? Clear is pure, synthetic vanillin. It's often called "crystal vanilla." Dark and murky is synthetic vanillin, most likely ethyl vanillin derived from coal tar. It may also be dark because it contains red dye that we've banned in the U.S. or it may contain caramel coloring. If it's truly amber-colored it may be natural vanilla.
* What is the alcohol content? Usually the synthetics range from no alcohol to about 2% alcohol (which acts as a stabilizer). There are some vanilla-vanillin blends and some cheap-quality vanillas that have 25% alcohol, but they aren't worth buying either.
* How much did you pay for it? This is the biggest tip-off. If it's in a big bottle and you paid $20.00 or less, it's absolutely not vanilla extract. Pure vanilla extract usually costs more in Mexico because only one company makes quality extract, and only in small quantities."
Also, beware of courmarin!
Coumarin is a the bad guy of the vanilla industry. It is derived from the Brazilian tonka bean from Dipteryx ordorata, a tree. The bean can be used to make flavoring very similar to vanilla. Sadly the concoction is dreadfully toxic and can cause liver damage and is a know carcinogen.
Coumarin is used extensively in synthetic vanillas manufactured in Mexico. The U.S. banned imports of the coumarin laced products back in the 1950's. Unfortunately the products still make their way into the U.S.
If you purchase any Mexican vanilla make sure it is clearly labeled "courmarin free".
