I tried to do just that, Francois, and I defrosted very slowly per classic cell/tissue preservation protocol, and I still didn't like the cams as much. They were OK, just a little different. Suitable for sale.
With the lactic curds, I couldn't really tell the difference after defrosting.
Another approach used commercially is UF with bactofugation. It makes for retentate that is stable at room temp and this way can be stored until needed, or shipped and made elsewhere.
