Chocolate is a beloved treat for many, but its delicate nature requires proper storage to maintain its quality and safety. One common concern among chocolate enthusiasts is the risk of mold growth when storing chocolate in the fridge. In this article, we’ll delve into the science behind chocolate mold, explore the factors that contribute to its growth, and provide valuable storage tips to keep your chocolate fresh and mold-free.
What is Chocolate Mold?
Chocolate mold is a type of fungus that grows on the surface of chocolate, typically in the form of white, green, or black patches. The most common types of mold that affect chocolate are:
- Aspergillus: A type of mold that can produce mycotoxins, which can be toxic to humans.
- Penicillium: A type of mold that can produce penicillin, but can also cause spoilage and off-flavors in chocolate.
