No, it hasn't. Freezing may kill some bacteria, but what it mainly does is keep bacteria from growing due to the low temperature.
Nevertheless, I do not pasteurize my fruit for fruit beers. I wash and sanitize it, then freeze it in a sanitized container, discarding any pieces that are obviously not fresh. Most of the wild yeasts (and other germs) you get from fruit are sitting around on the outside of the fruit, so washing the fruit thoroughly will usually take care of it. For whatever remains I just trust the alcohol in the beer to help out with.
Pasteurizing the fruit does denature the germs, but it also dramatically changes the flavor and texture. You just don't end up with as "crisp" a flavor IMO.
