<<Disclaimer: Verify this information before applying it to your situation.>> Thanks very much for all the responses. The consistent answer to whether modified corn starch is GF is yes. The manufacturer is clearly listing the source of the starch when specifying “modified corn starch” as opposed to listing “modified food starch" when then you would be uncertain as to the original source (wheat, potato, corn, etc...). *Support summarization of posts, reply to the SENDER not the CELIAC List*
