I am wondering if anyone could point me in the right direction. I tried looking in the PMO and couldn't find anything . Is there a shelf life listed for frozen raw sheep milk? Is it 3-6 months, a year.

 

Thanks

Nope.  Typically milk isn't recommended to be frozen.

 

I'm not sure if the PMO has any shelf-life information for fluid milk products, raw or pasteurized, as they leave that up to the state (if the state has specific requirements) or the processor / producer.

 

If it is raw milk, I wouldn't go more than 3 months frozen.  I think the PMO does reference sample handling and freezing milk samples for testing.  If I recall correctly, it is either 3 or 6 months they recommend.  But this is for sampling handling and testing, not product for processing, bottling, etc.

Milk should not really be frozen, it looses some quality characteristics. But typically from 3-6 months.

 

If you want to extend it's shelf like it's recommended to perform UHT.  But then again I am assuming you want to keep it raw?
