A Comprehensive Guide On How To Keep Bread From Molding

how to keep bread from molding

Bread is unquestionably a staple in countless households; it is versatile and simple to prepare food. However, one of the most prevalent issues with storing bread is its inclination to grow mold quickly.

Moldy bread isn’t just bad to look at and eat; it’s also bad for your health. So, how to keep bread from molding and extend its shelf life?

This post will provide practical and effective suggestions on keeping your bread fresh for extended durations, whether you are a passionate bread maker or a basic bread eater.

What Creates Mold?

To prevent mold from forming on bread, you must first understand what causes the mold. This allows us to eliminate the initial causes and extend the bread’s shelf life.

Mold species that grow on bread differ, but they are equally common in other meals.

Mold grows when its spores reach a food item’s surface and begin to consume the organic components on it. This causes them to develop into apparent mold.

Penicillium, Cladosporium, and black bread mold are the three most common kinds of bread mold. They all form and develop identically, regardless of which you have.

Mold growth is heavily influenced by oxygen, a food source (moisture and nutrients), temperature, and time.

  • Food Source

Mold must find a food source that has high levels of moisture to thrive. Moisture exists in all fresh ingredients, regardless of how they are prepared.

Moisture carries nutrients with it. Mold spores prefer sweet ingredients like strawberries over dried pasta, which provides fewer minerals and sugars.

In general, banana bread with a lot of sugar will mold faster than brown bread with less sugar.

  • Oxygen

The second most critical requirement for mold is oxygen. As living entities, spores require oxygen to grow and thrive. By removing it, you will significantly slow their growth!

  • Temperature

When storing any sort of food, temperature is an important factor to consider. Bacteria and mold respond differently to temperature.

The danger zone of temperature is between 40-140°F (4-60°C). Mold will grow on any goods stored at these temps.

Room temperature (68-72°F/20-22°C) is the best temperature for mold growth. This is where bread is most prone and will develop mold the fastest.

The colder it gets, the slower the mold grows, and at freezing temperatures, most molds die.

  • Time

Time is the last thing to consider when it comes to mold growth. If you keep ingredients out in poor conditions for too long, mold will grow.

What Happens When You Consume Moldy Bread?

Mold spores can get up your nose if you even smell mold on bread. Inhaling spores is especially risky for people who have a mold allergy or a weakened immune system.

Some molds create dangerous yet imperceptible poisons known as mycotoxins. These poisons may cause an upset stomach, change gut microorganisms, and potentially increase cancer risk in the long run.

How To Keep Bread From Molding?

Here are the best ways to how to keep bread from molding celery.

  • Use Bread Bags

They are cloth bags that look like tea towels and are an incredible way to prevent bread from molding. They are obtainable in an array of shapes and sizes and can be utilized on any sort of bread.

The bread bag is an easy and inexpensive way to keep bread fresh. It can also be reused numerous times, making it more eco-friendly than conventional storage techniques.

  • Use Paper Bags

The brown paper bag will absorb any water that drips off the bread and keep it dry. They allow for sufficient airflow and are not as restricting as plastic bags or an airtight container.

This is due to the ability of paper bags to absorb moisture and prevent mold from forming on the outside of the bread.

  • Use Linen Bag

A linen bag, like paper bags, inhibits mold by wicking away excess moisture. This is done because linen is breathable, allowing air to circulate around the bread, keeping it crusty and dry on the outside.

While plastic can cause bread to get soft or even soggy, the linen bag allows just enough circulation to keep the bread from becoming stale too quickly.

  • Store In Freezer

Bread can be safely kept in the freezer. You can do this by securely covering the bread in plastic wrap and then placing it in a freezer bag. This procedure can help your bread stay mold-free for up to six months.

Of course, you can freeze bread and bread slices, but don’t leave the bread in the freezer for a long time, or it will have freezer burn.

While this method does keep mold spores at bay, defrosting the bread may cause it to become soggy. And who likes stale, mushy bread?

Bread should be properly packed and placed on a shelf away from the refrigerator or freezer’s door. It must also be placed on a baking sheet or other flat surface to allow any condensation to drain.

  • Don’t Store In Plastic

This applies to both plastic bags and airtight plastic containers, as well as other plastics. A loaf of bread will lack the necessary conditions, and the limited airflow will allow mold to grow and stale.

Plastic bags are a serious environmental threat because they are neither biodegradable nor recyclable. They also encourage mold growth on bread, which can be extremely dangerous for folks who suffer from allergies or asthma.

  • Store In Kitchen Drawer or Cabinet

Obviously, this will not keep it mold-free because bread has a shorter shelf life when left at room temperature. It may become stale, but it is far preferable than leaving it in full sunlight and at high temperatures.

This is still a dry place, but it may create its own climate. It has the necessary humidity for mold growth.

The countertop is one of the finest places to store bread since it allows for better air circulation and is less expected to become moldy.

Wrap bread tightly in plastic wrap, aluminum foil, or wax paper before storing it in a cabinet or drawer.

  • Use Bread Box

The bread box is another fantastic invention that will help keep moldy bread at bay. They come in several colors, shapes, and sizes, and are an easy method to how to keep bread from molding.

It is a simple invention that is used to prevent bread from molding. Bread boxes are built of a variety of materials, including plastic and metal, but wood is the most preferred because it does not rust or corrode like metal.

  • Keep Bread Out of the Fridge

It is a frequent misperception that storing bread in the refrigerator would keep it fresher. In reality, the chilly temperature of the fridge promotes mold formation on bread.

Bread should be kept in a dry, cool place at room temperature. This applies to both homemade and store-bought bread, including French bread, whole wheat bread, and darker bread varieties.

  • Don’t Expose To Water

When bread is exposed to air and moisture, it swiftly goes stale. Keeping bread in a sealed container is the best way to prevent it from molding.

The container should be almost airtight as well as opaque or colored so that light does not enter and cause the bread to mold.

  • The Appropriate Amount Of Air Circulation

If you store bread in the refrigerator and keep it in its original plastic bag, it will go bad. Why? No air. The proper amount of air circulation is what keeps bread from molding and allows us to enjoy it for a prolonged period.

You should also guarantee that the containers are properly sealed so that only a small amount of air gets inside and that you check on them regularly to witness if there are any mold symptoms.

  • Use Preservatives

Bread can be preserved with a variety of preservatives, including sodium benzoate, potassium sorbate, and calcium propionate. These ingredients are added in smaller amounts and assist in inhibiting food spoilage and deterioration.

Ground ginger, cinnamon, or the finest option – garlic – can all be used as natural preservatives. They keep bacteria at bay. To keep them fresh, you can also use additives.

  • Bread Type Matters

White bread contains less water and is less prone to mold growth. Bread made from grains and seeds, such as rye, barley, and spelt, are even less likely to develop mold because their natural oils function as a preservative.

Numerous bread types are popular in various parts of the world. Baguette, pita bread, naan bread, and pastries such as croissants are all examples of bread with varying shelf life. However, you can always freeze them like cornbread or pita bread.

  • Avoid Pre-Sliced Bread

When purchasing bread, buying it whole rather than pre-sliced is recommended. Cut off what you need every time you make a sandwich or toast.

As pre-sliced bread is more exposed to air, it gets moldy significantly faster than unsliced bread. And with unsliced loaves, you may choose how thick you want your slices to be!

  • Cut The Bread In The Middle

Another method for keeping unsliced loaves of bread fresh and mold-free is to cut into the middle rather than from the end. Just continue pushing the bread together again before storing it.

The end crusts will keep the loaf fresher longer by retaining just enough moisture to keep it soft without becoming moldy.

  • Reviving Stale Bread

Keeping bread from molding does not prevent it from becoming stale. There’s no reason to waste the last few slices of bread because they’re stale.

There is a technique for reviving stale bread so that it can be used; simply place it in a warm oven for a little while. Place the entire loaf, or a few slices, on a parchment-lined cookie sheet.

Heating for 3 to 5 minutes can soften the bread and make it almost as fresh as new.

  • Toast Your Bread

Toasting bread is one of the best and tastiest methods to eat stale bread that you’re concerned will mold soon! Toasted bread with butter is delicious in the morning, noon, and night.

How Long Does It Take For Mold To Grow On Bread

  • Play With The Recipe

Are you creating your own bread? Nothing beats a freshly baked loaf right out of the oven. Due to the lack of preservatives, homemade bread simply does not survive as long as store-bought bread. But that doesn’t mean you’re out of luck.

While many of the above guidelines will help you how to keep bread from molding, there is one specific secret I’d like to share with you: experiment with the recipe to discourage mold.

How? There are three options for doing so:

  • Add more flour to make denser bread that makes mold growth difficult.
  • To completely eliminate mold, use more acidic ingredients.
  • Consider using a natural preservative like lecithin or lactic acid in your bread (cinnamon, garlic, and honey also work, but they will change the flavor of your bread).

Besides, once your bread has cooled and you’re ready to start slicing it, start in the center and work your way outwards.

Push the halves together once you’ve sliced out portion of the bread. This keeps the bread “intact” and prevents mold from growing on it.

How Long Does It Take For Mold To Grow On Bread?

Mold on bread can develop in as little as 24 hours, but it can also take up to ten days to grow. Mold spores emerge in most breads after 5 days.

The rate of mold growth on bread is also affected by the type of bread used. Rye bread, for example, will grow mold faster than whole wheat bread because rye has more sugar than whole wheat.

The temperature also influences how rapidly mold grows on bread. If it’s too chilly outside, the growth rate will be slower than if it’s too warm.

Another element that influences how quickly mold forms on a loaf of bread is humidity. If the humidity is high, the growth rate will be faster since there is more moisture in the air for mold to feed on.

Does Refrigerating Bread Prevent Mold?

The fact is that storing bread in the refrigerator prevents mold from forming on it. However, I would not recommend storing your bread in the refrigerator.

To understand why refrigerating bread is a bad idea, we must first understand why bread goes bad in the first place. Bread stales faster when refrigerated because the starch molecules inside quickly solidify.

This technique generates an ideal environment for mold growth, which can then form on top of or inside the bread. To avoid mold, keep your bread in an airtight box at room temperature, away from moisture or humidity.

Why Does Bread Mold So Fast In My House?

If you reside in a humid region or have high humidity levels in your home, your bread will mold faster than if you reside in a dry environment with lower humidity levels.

This is because moisture promotes yeast development and accelerates the fermentation of sugars into alcohols and acids, which subsequently decompose into carbon dioxide gas bubbles, causing the dough to rise even faster than before.

Bread mold is a common issue for many people. It can be caused by an assortment of circumstances, including bread type, home temperature, and humidity.

How To Prevent Mold On Store-Bought Bread

Now that we’ve learned how to keep bread from molding, here are a few pointers on how to do it accurately when you need to know how to prevent mold on store-bought bread:

  • Storage is key

One method is to keep the bread in a cold, dry place. Another method is to keep the bread away from moisture and humidity.

  • Moisture

You should also avoid storing your bread near other foods that may have moisture on them, such as vegetables or fruits.

  • Air Circulation

Put it in a bread box or container. Avoid wrapping the entire loaf of bread in plastic wrap or foil.

  • Don’t Use Plastic Bags

Remove it from the plastic bag and, if possible, avoid purchasing pre-cut bread.

  • Expiration Date

If you’re unsure how long your bread will last, look at the expiration date on the packaging.

If you don’t plan on consuming it within a few days, store-bought bread should be kept in the freezer. If you wish to retain your bread for a longer period, freeze it and defrost it as needed.

Does Refrigerating Bread Prevent Mold


There are numerous methods for preventing bread from growing mold so quickly.

Keep the fresh loaf dry and at a low humidity and temperature. Mold can be avoided by storing bread in cloth bags, a clean tea towel, brown paper bags, or the freezer.

Darker bread, such as whole wheat, sourdough, and rye, keeps mold at bay longer than lighter bread, such as white French bread.
