However, if chocolate is left in a high temperature environment for a long time, it may melt and deteriorate, and it is not suitable for eating at this time. Besides, don't eat chocolate when it's expired.
Therefore, it is suggested that when you buy chocolate, you should pay attention to the shelf life and preservation methods on the packaging, and properly preserve the chocolate to avoid its deterioration. Chocolate with frosted flowers or white spots is edible if it has not expired and is properly preserved.
