How to keep bread from Molding

In this article, we will teach you everything about how to keep bread from molding. This includes the best practices for storing bread and the different ways to prevent mold from forming. You can learn everything you need by reading on!

Meaning of Mold

The substance that causes food products to spoil quickly. Moldy bread is pretty easy to spot, and can cause serious allergic reactions in those who have an allergy or sensitivity to it: bread that’s no longer fresh and palatable but still looks “okay”.

Mold is a widespread problem affecting almost all food products, such as bread and confections. Bread can get moldy due to the yeast or bacteria getting out of control; this happens mainly because people leave their fresh loaves exposed on prep counters for too long without storing them properly. 

The conditions these foods need – temperature, humidity, cleanliness, and air circulation, among other things – are rarely met in commercial kitchens and homes. Typical methods of preserving bread are ineffective against mold since they contain chemicals (preservatives or acids) that can have the opposite effect: they kill the yeast while creating a hospitable environment for bacteria.

Some Signs Describe That Your Bread Is Moldy

First, here are some basic signs of bread that might be sourdough or not:

  • A strong and strange aroma. This is not a sure sign because some overpowering fragrances can be associated with pasture water instead of sourdough or yeast contamination—but it still warrants further investigation.
  • If you detect a sour smell, moldy look, or black patches on the bread, then it is most likely that you have mold growing on the bread.
  • You can also try to slice the bread and examine the inside for signs of mold.
  • Discard the bread if it is found to be contaminated.
  • It is most likely mold if you find black or green spots on your bread.
  • The spots will also grow in size when the bread is stored in moist conditions.
  • You can identify mold by its slimy texture, foul odor, and brown or green color.

What Causes Mold On Bread

A very popular question is what causes mold on bread. Many factors can cause this contamination:


It is important to remember that moisture accumulates in the bread. Keep your bread in a sealed container or bag away from water sources, like air conditioners and dehumidifiers.


Bread is more vulnerable to heat and humidity at room temperature. So, you need to be careful to keep away your bread from high temperatures and humid areas.

Fungi Spores

The fungus that causes bread mold either grows outside the loaf (in humid environments) or penetrates through a hole and colonizes inner shelves. Microorganisms remain dormant in proper storage conditions but become active when exposed to inappropriate temperatures, moisture, salt, and acidic ingredients.

High Humidity

Mold or yeasts grow most effectively under high humidity conditions, and food products left exposed to these conditions may generate mold growth as a result.

Baking Soda

Baking soda is a common ingredient used in baking. It’s frequently used to replace the manganese found naturally in flour with added benefits such as raising yeast production, stimulating oil production, and keeping bread fresh for longer periods.

How To Keep Bread From Molding

Humidity, warmth and light help to increase the mold of the bread. So bread should be kept in a cool and dry place away from light to prevent mold. You can use some of these tips to help keep the bread from molding:

Keep your bread in an airtight bag

To prevent mold from forming, store your freshly baked bread in an airtight plastic bag overnight. If you are baking a large amount, such as 30-40 loaves of bread or more, it is advisable to let the last loaf rise all day before placing them into storage bags.

Keep away from humidity

Mold will only form where there’s humidity – so make sure none of these things happen: don’t place dirty plates, pots, or pans into the refrigerator with your bread containing spilled food.

Kitchen cabinet

If you leave stray bread crumbs on a surface that is transferred to another surface – say inside a glass door in your kitchen cabinet or next to some cutlery drawer – mold can start forming where it once touched this contaminated item. 

Clean up all spills as soon as possible after baking to avoid unattended exposure to bacteria and bread-borne mold spores.

Keep your bread dry

Bread cannot get wet. Do not leave bread uncovered, even in the oven, especially with a plastic bag. 

Do not reuse plastic bags

Do not reuse plastic bags that have been used for bread or other baked items. The best way is to use new ones since a small amount of leftover dampness is stored in the bag which cannot create moldy conditions.

Use a Bread Box

If you want to keep your bread safe and germs-free, use the bread box. A bread box is one of the best solutions. On the other hand, the bread can be kept in an airtight moisture-proof container. For this reason, they are never touched by any mold, insects, or bacteria. We’ve listed some of the best bread boxes available on the market, you can pick the one you like.

Toast your bread

Another way to keep your bread mold-free is to toast your bread. Toaster ovens have special high heat settings, which will dry the bread and help it last longer. You can also use a basting brush to coat your toast in butter or margarine to prevent mold from forming.

Use bread bag

You can use a bread bag to prevent mold. The inside of your bread bag is naturally antifungal. The cloth bread bag is similar to a bread box but takes up less space. Keeping the bag tightly closed restricts air circulation while allowing just enough air to flow. Bread bags come in many cute designs.

What is the best way to store bread?

  • To keep bread fresher for longer, wrap it in plastic, a reusable zip-top plastic bag, or a bread box.
  • Avoid keeping bread in wet, airy areas since this might hasten mold growth.
  • Bread should be at room temperature (close to 70 degrees Fahrenheit or 20 Celsius) before serving, but the refrigerator is not a suitable place for bread. Like most food prepared in high temperatures, it gets soggy and sometimes moldy quickly.
  • Dry toast on both sides and cool completely before cutting into small pieces that can fit into plastic containers without getting squashed by other foods inside your kitchen cabinet. And always take appropriate steps when transporting bread products to ensure they won’t get crushed inside a bag or cabinet.
  • You should leave the bread uncovered for a few hours after making it. After baking, leave the bread discovered on the counter until ready to store it for the night. The bread will breathe.
  • Place your homemade bread in a bread box and wrap it in foil overnight. To preserve freshness, wrap it in foil and store it overnight in a breadbox. With enough air, you can keep your bread moist and crisp in a breadbox.
