Answered by Chaim Yisrael Abadi

It is corn usually. CYA...” Would the following quote from fda.gov take modified food starch out of the category of “usually” corn into a more definitive halachicly accepted status? “the term "starch" is considered the common or usual name for starch made from corn; alternatively, the name "cornstarch" may be used. Starches from other sources should be designated by some non-misleading term that indicates the source of such starch, for example, "potato starch," "wheat starch," or "tapioca starch." “ http://www.fda.gov/ora/compliance_ref/cpg/cpgfod/cpg578-100.html Thanks
