I know, that's the wiki I read before I started this. It's STILL the ingredient in TFA "SWEETNER", maybe a better way to pose the question is what are the differences, as it's an ingredient NOT listed in the product description. Sorry, I'm not a chemist.
FROM THE WIKI:
Maltol is a naturally occurring
organic compound that is used primarily as a
flavor enhancer. It is found in the bark of
larch tree, in
pine needles, and in roasted
malt (from which it gets its name). It is a white crystalline powder that is soluble in hot water, chloroform, and other polar solvents. Because it has the odor of cotton candy and caramel, maltol is used to impart a sweet aroma to fragrances. Maltol's sweetness adds to the odor of freshly baked bread, and is used as a flavor enhancer (INS Number 636) in breads and cakes. It is not registered as a food additive in the EU and thus has no E-number.
[1] Instead, maltol is registered as a flavor component in the EU.

Maltol, like related 3-hydroxy-4-
pyrones such as
kojic acid, binds to
hardmetal centers such as Fe3+, Ga3+, Al3+, and VO2+.
[3] Related to this property, maltol has been reported to greatly increase
aluminum uptake in the body
[4] and to increase the oral bioavailability of
gallium[5] and iron.
