<<Disclaimer: Verify this information before applying it to your situation.>> Two responses I received regarding dextrin: See the excellent site www.celiac.com, specifically the "Safe and Forbidden Lists" page: http://www.celiac.com/forbiden.html Dextrin appears on the forbidden list because depending on the source, it _may_ be derived from a gluten-containing grain. See the extensive footnote there. The following quote is from Scott Adams website, which I have found particularly trustworthy: http://www.celiac.com/forbiden.html My best. -vance "Dextrin is an incompletely hydrolyzed starch. It is prepared by dry heating corn, waxy maize, waxy milo, potato, arrowroot, WHEAT, rice, tapioca, or sago starches, or by dry heating the starches after: (1) Treatment with safe and suitable alkalis, acids, or pH control agents and (2) drying the acid or alkali treated starch. (1) Therefore, unless you know the source, you must avoid dextrin. " FOOTNOTE: I'll be contacting Burger King to ask their source. However, I also received an email from a gal in Tennessee that said she checked the ingredients at her local BK and the fries there contain dairy products and dextrin! Not so in NJ. I guess only an inquiry directly to BK will tell the whole story.
