果汁的use by date过了也是能够喝的,条件是保留妥当,合适饮用,如楼主这类状况
4. It is out of date – is it alright?
The juice does not become spoiled on the use by date. The juice will last past this date as long as it has been stored properly. The quality may not be as good as when first made. It should be assessed if it is ‘fit to drink’. If in doubt throw it out. FRom fruitjuiceaustralia.org
