It absorbs odours
Chocolate easily absorbs odours of whatever is in the fridge. Think, when you want that rich chocolate taste and you get garlic or onion smell! Store in an airtight box to avoid this!
Moisture leads to sugar bloom
The sugar rises on the surface and discolors the chocolate if kept for long in the fridge. You must have seen a white layer on it if you take them out after a long time.
Makes it dull
Chilling chocolates makes it dull as after freezing for long they lose the real flavour.
Store in airtight container
It is recommended to store them in an airtight container as it saves its taste from ruining.
Freezing reduces its life
If you are freezing your chocolates do not keep them in the fridge for long. Keep only for a shorter time and eat them as soon as possible.
