Vegetables can still be eaten after freezing if they are not spoiled, but they cannot be eaten if they have a sour odor or other conditions.
Generally speaking, to determine whether vegetables can continue to be eaten after freezing depends mainly on whether there is a change in the appearance of the vegetables as well as an abnormal odor. If no deterioration occurs after the vegetables are frozen, such as rotting, turning yellow, etc., this situation can continue to be consumed.
