Mold - A living organism

Bread is an ideal place for mold to grow because it provides the food and conditions that they need. But, it’s still important to keep an eye on your bread so that you don’t have any mold growing on it!

Types of Mold

Breads that are enriched and sold at the supermarket are prone to molding because they have additives to make them last longer. If you want to reduce the risk of your bread growing mold, you should store it in an airtight container or wrap it up in a plastic bag when not in use.

If you're storing your bread in a pantry, you'll want to keep it out of the sun and off the countertop. You should also try to store it in a cool, dry place instead of a warm and humid one, as this will help prevent mold from growing.

Preservatives and Salt

The amount of preservatives in your bread will have an effect on how quickly it molds. Commercially distributed and enriched breads tend to have more preservatives than homemade or organic breads.

Moisture levels

Moist and wet breads will grow mold faster than dry and hard breads. The reason for this is because mold loves damp environments and needs moisture to survive.

Light level

You can test this by placing different bags of bread in a variety of temperatures and different light levels to see how mold grows under these conditions. You can also experiment with different types of bread, such as whole wheat, rye or white bread.
