refreezing slightly unthawed meat?
if you freeze food in a no frost freezer, that is where you lose moisture... the no frost feature cause moisture to be removed from the freezer, and eventually the items inside... for example, if you have ice cube trays that have been in there for an extended period of time, notice how the cubes shrink? That because of the no frost
best for long term storage is a freezer that isn't frost free... yea, you will have to defrost the whole thing once a year or so... I do this in the winter, put frozen goods in coolers, and set them outside in the snow... then let the freeze defrost/drain
makes a big difference
I personally prefer plastic wrap over vacuum sealers for meat. Tightly wrapping with plastic wrap will keep air off the meat no matter what. It's cheaper and does (IMO) work much better. Vacuum bags frequently lose the seal at some point in my experience and ruin whatever is inside. Plastic wrap just stays where it was when it started. I'm sure there are some commercial grade air suckers that work great. But plastic wrap is way cheaper and still has 100% chance of keeping air off meat from day one. I don't like to keep any meat frozen very long but I have thawed meat over 1 year old that was wrapped in plastic and was still like it was before I froze it.
For those of you that continue to use the vacuum sealer, if the vacuum held, break the vacuum (cut the bag) before thawing so that the vacuum doesn't suck the moisture out of whatever is inside.
