The message
from "Brian" --- 'flayb' to respond contains these words:

Many years ago I was at a conference where this question was asked.
Their answer was "We 'flash freeze' at much lower temperatures than you can
achieve and this avoids the need for other treatment".
They demonstrated that their methods could be used for strawberries and
keep them whole~ but actually broke when dropped!.
Best Wishes Brian.

I did a fish handling course at Torrey Research Station and some
professor arrived with a big vacuum flask of liquid nitrogen and a small
cod.

Demonstrating that the cod was quite floppy, he dunked it in the liquid
nitrogen and left it on the desk for a bit. About five minutes later, if
that, he removed the cod and used it as a hammer to knock a six inch
nail into a block of wood.
