1. Cold dishes should usually be eaten as soon as possible, but if they cannot be eaten at once, they should be kept in the refrigerator to keep them fresh. Usually cold dishes have a shelf life of 1-3 days.

2. It should be noted that the longer the shelf life is not the better, because to keep it from deteriorating, preservatives must be added to it. Therefore, the longer the shelf life of cold dishes, the more preservatives may be added, so Buy as much as you can.
