<<Disclaimer: Verify this information before applying it to your situation.>> SUMMARY OF RESPONSES - modified food starch. "In Canada it means 5% wheat starch." "No known law regarding what food starch must be...generally...means wheat starch--corn, the other primary option...is more expensive." "This is a term used for what ever is cheapest at the time...could be anything." BOTTOM LINE - call the company and inquire if their product is something you especially like. Thanks to all who responded - it sure helps. Catherine
