Generally you can freeze any meat that hasn't been previously frozen (freezing twice destroys the cell structure resulting in pour texture and flavor.) Vacuum packing simple removes any air from inside the package, which generally allows meat to keep for longer. If you plan to freeze meat, it is best to leave it in the vacuum pack, but not necessary. Re-wrap meat in a freezer bag and remove as much air as possible before sealing.
No. Not unless it was shelf stable without the vacuum packaging. You cannot put raw hamburger or a cooked steak into vacuum packaging and not refrigerate it. The vacuum might discourage some bacteria, but others - like Clostridium botulinum - love to grow and form toxins under anaerobic conditions.
If you have a sharp enough knife, sure. It will probably be extremely difficult to cut beef while it was frozen with your household knives.
Vacuum packed beef should be good for 4 to 5 days.
With a knife.
None, Discard beef not frozen at expiry date. From 0 to 3 days or more depending on the conditions of storage (the entire chain from slaughterhouse to store to your storage: Temperature, humidity, contaminants, covered, open, etc...
yes, but don't freeze it in the jar.
If you don't keep it open then, yes it will still be fresh. But if its been open for a year then it won't be fresh...
With a can opener
Out of doors, something out in the open would freeze first. That's why people cover delicate plants when a freeze is expected.
It's a valve that can open an hydraulic circuit befor the water inside freeze.
Chicken eggs do freeze in the shell. Freezing will cause the egg to expand and crack open. Frozen eggs in the shell change consistency and will not cook, taste or have the same texture as a fresh egg. Special preparation before freezing will render the eggs useable when they need to be frozen.
That all depends. If the broth is packed in a ziplock bag it probably won't last anymore than 3 days, but if it is packed into an air tight container it will probably last about 5 or 6 days.
No
Yes you can I steam them a little first to open shells Then shuck them and freeze them in the broth (cooled) If quahog is open before steaming Throw it away If you can't open it easy after steaming throw it away
Open tubular columns provide greater resolution than packed columns in gas chromatography because of their large retention time.
