Chocolate can be kept in the refrigerator. Because the melting point of chocolate is generally around 35 degrees Celsius, if the temperature is high in summer, it may melt and deform at room temperature, so it is ok to put it in the refrigerator for cold storage. However, because there is more water in the refrigerator and the environment is humid, if it is left for a long time, the sugar in chocolate may react with water and form a layer of white icing on the surface.
Chocolate can be frozen, but it is not recommended. Because chocolate will become hard and taste worse after long-term freezing, generally speaking, it is not necessary to put it in the freezer as long as it is placed in a cold room or a low-temperature ventilated place.
Chocolate still has requirements for preserving the environment. If the temperature is not high, it can be stored in a dry and ventilated place. If the temperature is high, it can be stored in a cold room to avoid melting.
