Why does vacuum packed chicken smell?
Similarly one may ask, why does vacuum packed meat smell?
Meat that has been deprived of oxygen will become darker. This smell is in no way an indication that there is a problem with the meat. It is known as "confinement odour" and is a result of the vacuum sealing process. After a few minutes, the smell will disappear and the colour will return to normal.
Also to know, should packaged chicken smell?
Smell the chicken. Raw chicken that has gone bad has a very potent odor. Some describe it as a "sour" smell, while others liken it to the scent of ammonia. If the chicken has begun to take on an unpleasant or strong odor of any sort, it is best to discard it.
If you store it in the freezer in a sealed, freezer-safe container or vacuum-sealed package, it should stay safe to thaw and eat for up to 9 months, in pieces, or up to 12 months, for a whole chicken.
