Here is an email response which was sent to an inquiring mind from this site...
You can contact any Avidin / Biotin Antibody Laboratory in the country to verify this for yourself. Avidin is neutralized at a very low heat of only about 110 degrees. I don't know where your would have gotten 185 Degrees. This is hotter than normal pasteurization would be. The Egg would be cooked by then.
We do a low heat pasteurization of only 134 degrees for 3 1/2 minutes. This process keeps the Egg Whites moving through a series of tubes to keep them from cooking. By using this low moving heat process, we can keep the integrity of the protein intact, yet still kill all Salmonella and Listeria, and Neutralize the Avidin.
See our Website for more info if needed.
Feel free to contact me with any other concerns.
Sincerely,
Ray "Mac" McCabe
