Ever heard of Senomyx?

I hadn't heard of Senomyx until I saw it mentioned on Natural Health News blog. Senomyx is a food additive that got approved very quickly. It can enhance flavors and even block bitter flavors. I looked up Senomyx on Wikipedia and found no comfort there. Companies can include put it in food without saying so!

"Senomyx has identified the receptors in the mouth responsible for sensing bitter taste (nature’s way of warning us against ingesting poison) and developed a chemical additive to knock out these receptors..." How's that for a bad idea?

As a person with food allergies and sensitivities, I object to any additive being allowed without being identified. If I should be have a reaction to the additive, how could I identify it and later avoid it?

Could Senomyx be one the secret "natural flavors" in Truvia? Could it be the one that has caused gastric distress in the dozens of people who have complained about Truvia here?
