Why Do Biscuits Turn Mouldy?

Biscuits can turn mouldy if they are exposed to moisture, which creates an ideal environment for mould growth. Mould spores are present in the air around us, and when they land on a surface that is moist and has nutrients (such as the sugar and flour in biscuits), they can start to grow and multiply.

There are several reasons why biscuits might become moist and promote mould growth:

Exposure to humidity: If biscuits are stored in a humid environment, such as a damp kitchen or a pantry without proper ventilation, they can absorb moisture from the air and become moist. This can lead to mould growth.

Improper storage: If biscuits are not stored in an airtight container, they can be exposed to moisture from the air and other sources, such as spills or splashes.

Contamination: Biscuits can also become contaminated with mould spores if they are stored near other mouldy food items, or if they are handled by someone who has touched a mouldy surface.

To prevent biscuits from turning mouldy, it’s important to store them in a cool, dry place in an airtight container. Avoid storing biscuits in a humid environment, and try to keep them away from other mouldy food items. If you notice any signs of mould growth on biscuits, it’s best to discard them to avoid the risk of consuming mouldy food.
