I forgot to eat the bagged Beijing roast duck sent by my friend. The shelf life on it has passed, but the packaging inside is very good and there is no smell in vacuum. Please. ...

The shelf life of this kind of food is generally the earliest date that will deteriorate according to the packaging conditions, which is also an estimate. The canned food sterilized at high temperature has a long shelf life, and there will be no problem within two months after expiration. This kind of roast duck is fine for a month, but it's best to heat it when eating! !
