Freezing RTD Protein Shakes

[golfGirl]

Does anyone know why the RTDs say "Do Not Freeze"?

Do you think it's because the consistency won't be good when you thaw it or do you think freezing somehow compromises the protein?

I love to freeze them and eat them like ice cream.

Any thoughts?

Thanks!!

of what I know about protein stability, freezing (and heating) can actually damage/denature proteins. That is why purified proteins are typically stored in glycerol solution when maintained at freezing temps. since glycerol lowers the temp. at which ice crystals enlarge and cause damage.

hope this helps
