Re-freezing is generally not advised because each freeze-thaw cycle negatively impacts the quality of the food. The cell walls become damaged and leak, so the food either becomes mushy or dry and tough.
There are also microbiological concerns if the food has not been thawed or held properly.
No, never refreeze anything.
Yes. But, any damage is done during the thawing. If you thaw in the refrigerator at 5C you can refreeze. if you cook the beef after thawing once you refreeze it, but if you thaw the beef the first time at room temperature you are risking food poisoning when you thaw the beef a second time
No, it would not be safe to refreeze bacon, or any food, without cooking it first.
Yes. When you thaw them they be mushy but you can still use them.
no you can't because it will go off and if you reheat it,it will explode and will not be eatable.
The term 'unthaw' is used interchangeably with 'thaw'. They mean the same thing. It does not mean 'refreeze'.
No, it is not safe to thaw and refreeze breast milk. Once breast milk has been thawed, it should be used within 24 hours and should not be refrozen. Refreezing can lead to a loss of nutrients and potential bacterial growth, which can be harmful to the baby.
The general rule for refreezing foods that have been thawed, is that you should only refreeze if there are still ice crystals present in it, or after it has been cooked. If you do refreeze, you should also reduce the amount of time before you use the food as well, since the partial thaw may have allowed spoilage to progress slightly.
The refreeze warning is focused on defrosting, rather than cooking or even slow-thawing them. If you thaw open at room temperature, with warm water, or in the microwave, the edges and surface, which is where bacteria are probably dormant, warm up first and start to grow. Refreezing does not kill them, so you have greatly increased risk if you refreeze and thaw the same way, which most people would do. If you thaw and immediately cook the food, that basically starts you over with a fresh product (cooked <whatever>) that you can safely freeze afterward. Once frozen, the same cautions should apply to this food as well. If you thaw in the refridgerator, you have less risk, but the food ages(and bacteria etc grow) at the same rate as if it was refridgerated from the start. Most people don't realize this, and treat once-frozen food like it will last longer than not frozen, not realizing it was probably refridgerated before it was frozen and is effectively already older than their fresh food. Since this age is generally unknown, not eating right away is not recommended.
That would depend on how long it has been thawed I have done so without any bad effect however I did make sure that the meat was well cooked when I did eventualy use it,just in case.
Yes, you can thaw, cook, and refreeze chicken.
Yes, of course you can if it has been handled sensibly. The safety will depend on proper handling. See a USDA or agricultural extension service site for proper food handling instructions. The quality will suffer. it will tend to dryness more after the second thawing and will benefit from a brine soak and marinade before roasting. If you can use it in a sauce you will have better results.
