I hope it is not too late to comment on your post. I have just stumbled over your blog, and have been reading “backwards” through your posts. I am toying with the idea of going raw, but want to wait a bit until I am better informed, and summer is here so it will be cheaper. Anyway, I work in the Food Industry, and IQF means they harvest the berries at their ripest, and after washing etc they go onto a conveyor belt, spread out so they are separate, and then go into a chamber where they are sprayed with a very cold liquid, sometimes liquid nitrogen, at -20 degrees or so, so the berries freeze instantly and don’t suffer any celular damage. Nitrogen is an inert gas, so I doubt it is interfering with your healing, but would switch to fresh when they start to be available (British strawberries are in season now!)

Anyway I found this online. I hope it helps! http://www.encyclopedia.com/doc/1O39-quickfreezing.html
