PO Box 4800 Fullerton, CA 92634-4800 There have been some postings lately about their products such as the soy sauce and their booklet which shows it as not being gluten free. I want to share my information about their booklet which I received last year. After receiving the booklet which is a chart form and it has letters which stand for hvp, distilled vinegar from wheat or corn, corn etc. The booklet has AD for the soy sauce which states hydrolyzed vegetable protein: may contain trace amounts of gluten and contains carmel color made from corn. I wrote to the company questioning the AD because the label of the ingredients is clearly labeled hydrolyzed soy protein. I received a response which was a letter stating that there are errors in the booklet. They sent a booklet with yellow sticky notes of the corrections on all the pages with errors. The soy sauce should read only a D which stands for carmel color made from corn and therfore is Gluten free. My doctor who is Celiac uses it with no problems. It does have a preservative and that may be what bothered the list member or the soy. I'm sorry to hear that the company hasn't revised the booklet yet and that they failed to notify with a note about the errors to someone who was asking about gluten. Hope this helps. Diane
