One of the ingredients (IIRC) is sulfuric acid.
Uh....no.
Like I said, "IIRC". Instead, read the following:
Source:http://en.wikipedia.org/wiki/High-fructose_corn_syrupA pilot study reported that some high-fructose corn syrup manufactured in the U.S. in 2005 contained trace amounts of mercury. The mercury appeared to come from sodium hydroxide and hydrochloric acid, two chemicals used in the manufacture of high-fructose corn syrup. The caustic soda used by HFCS may be produced in industrial chlorine chlor-alkali plants using the mercury cell Castner-Kellner process, and may contain traces of mercury if this specific process is utilized. Mercury concentrations in the samples testing positive ranged from 0.012 μg/g to 0.570 μg/g (micrograms per gram). Nine of the twenty samples tested did contain measurable amounts of mercury.[53]
The only thing that's particularly noteworthy there is the mercury levels. If you follow the articles for both sodium hydroxide and hydrochloric acid, you'll see that they're both used in the preparation of many food products.
