<<Disclaimer: Verify this information before applying it to your situation.>> I remember reading that corn syrup had vanilla in it . Sure enough my bottle of Karo brand corn syrup lists vanilla. I will contact the manufacturer to see in what form it is added. My question is...Is the ingredient corn syrup listed on many labels pure corn syrup or does it usually have vanilla in it. I never had considered it a possible source of gluten when I saw it listed as an ingredient. I just rejected some apple sauce because corn syrup was listed. I am also wondering about glycerine. I found a brand of vanilla that was in glycerine not alcohol, but I am unfamiliar with glycerine as an ingredient. Thanks to all in advance. Irma in Massachusetts
