<<Disclaimer: Verify this information before applying it to your situation.>> Several of you have asked about the reference source I cited for the question about bentonite. I just bought this book, and it's amazingly complete: 8,000 food additives are described in detail. I just wish that there was an edition later than 1994. At least it's still in print and should be readily available, but probably by special order. ------------------- A Consumer's Dictionary of Food Additives by Ruth Winter 4th edition, Crown, 1994, list price $15.00 ISBN: 0517881950 ------------------- Nancy
