Freeze Dried Cultures - Past Expiry Date
« on: May 01, 2012, 06:58:03 PM »
The time has come to again begin making cheese. Looking into the freezer... I have the following (opened) cultures and I am wondering if I should toss them, use them, or somehow test them.

Expiring Dec 2010 (yikes!)
MA11

Expiring March 2011
MM100

Expiring May 2011
TA61
LM57

any feedback appreciated. I would love to not have to toss these, but I dont want to take much of a gamble and end up wasting time and milk...

Make up sealed jars of sterilized milk, add a little culture to each, and leave in a water bath at the appropriate temps (75F for lm, 85F for meso 100F for thermo). If they set, you're good. Might need to add just a little more or do a longer ripening

Most of mine have expired and they still work, then again they are probably degraded which might be my problem, cheese making that is.
