To be as fair as possible, I'll conduct a bread/mold tests as well and post my results along with some of my previous test data for your review. In addition to this, I'll be sure to include other brands in the experiment so as to promote a fair and balanced review - after which, I'll follow-up with a link to the documented experiment and results afterwards.
NB. While searching for the Utopia-silver bread /mold test in the forums, I discovered that over 93% of the 640 results relating to Utopia-Silver came from yourself and your wife. All of which appear subject to the promotion or soliciting of Utopia-Silver products over the course of 10 years. And while I can appreciate your commitment to your partners product or business, I'd remind you that affiliates will always be subject to protecting their own interests(see).
