Rennet, Aqueos - Frozen, OK To Use?

[tananaBrian]

Does freezing of liquid animal-based (cow) rennet damage it in any way, or reduce its effectiveness?  What if "freezing" means down to -15 F or so?

Thanks,
Brian

You cannot freeze liquid rennet.

Once refrigerated, rennet can last a very long time (1 year?), but gradually looses it's potency or effectiveness over time.

I was afraid of that.  Someone is shipping me some rennet, a gift you might say, and I didn't remember the fact that we'll be out of town as of tomorrow for 2 weeks.  It's 2 below zero right now.  If the package doesn't arrive today, then it'll show up while we're gone and the rennet will freeze solid before we get back.  Ooops?     It's OK though.  I'll get some more...
