Frank, when I blanch my tomatoes I find the entire tomato gets warm. To be safe, I would recommend saving seeds from tomatoes that you aren't going to blanch. A single tomato has a good amount of seeds so unless you're lucky enough to have a huge tomato garden, I'd think a few un-blanched tomatoes would be all you need.
