I might add powered milk and complete pancake mix.
We bought both at Sam's Club a few weeks ago to repackage and seal in gallon mylar bags with oxygen absorbers.
One night we repackaged 2 mylar bags of powdered milk and several bags of beans. We put oxygen absorbers from the same pack in all the bags. Everyone of the bags of beans vacuum sealed down very tight, but both bags of powdered milk never shrunk down a bit. I know it should not be a problem with the oxygen absorbers or the seal, so I'm stumped why the mylar bags full of powdered milk didn't create a vacuum like the bags of beans.
bjorn14~: “ I might add powered milk and complete pancake mix.”
powered milk : Yup !
complete pancake mix : with reservation !
Check the ingredients ~ Long term storage of pancake WITH EGG , may lead to samonella .
Pancake with egg ingredients ~ store for no longer than 6 - 8 months (in zip-lock baggie for moisture protection )
Pancake mix is pretty risky in long term storage.
