This glycerol based mixture stops and protects against damage to your organs and tissues by hindering the formation of ice crystals. This process is called “vitrification” and allows cells to live in a sort of suspended animation.
For a tomato to remain a tomato the water would have to be removed in a process similar to the above. And then rehydrated somehow at the thawing stage.
So in essence the tomato would have to be dessicated first, ergo, you are not freezing a tomato really.

Thanks, DP, sort of rules out bringing you back to life, full of antifreeze, doesn't it?
Still, if they could do it you'd make a good Antarctic explorer, wouldn't you? No need for all those warm clothes.
Doesn't explain how they freeze sperm and eggs though. I'm sure they're not full of antifreeze, if they are we're pushing evolution hard!
