In every country in the world we all have our own bread variations, with different tastes, shapes, colors, textures, sometimes savory and sometimessweet like American bread. Oftentimes, bread can be topped with delicious toppings to add that extra flavor.

Sometimes it may have cheese melted on it, sometimes seeds or fruit, but most commonly you'll find savory loaves of bread dusted with flour. That can be the case in small bakeries with their fresh bread, but can also be found on your bagged and sliced ​​breads at the grocery store.

Often people see this as white mold on bread or vice versa and mistake mold for flour. Today I'm going to look at how to tell if it's bread mold or flour on the bread, why both are there, and if either one is bad to eat.

Why is there flour on my bread?

Very often bread, especially fresh loaves, is dusted on top with flour. This can have several reasons:

Makes love distinguishable

Often bakers produce large batches of multiple loaves throughout the day and so using a specific flour on specific loaves can help them differentiate the loaves.

Prevents sticking during baking

However, the main reason for this is that the dough is dusted with flour before baking. This is to help prevent the dough from sticking to the baker's hands while he is working with it, but also to the tray or basket when it goes into the oven to bake.

Most of the time, the bread is left with excess flour, which remains on the surface of the loaf and results in a white powder on the bread.

Gives it a rustic look

With flour often left on freshly baked bread, it's now associated with classic, traditional bread made in a small, local bakery - which people love! For this reason, the bread is often dusted with flour after baking to give it a rustic, freshly baked appearance.

Therefore manySour Dough Bread, including bread packaged in supermarkets, can also be dusted with flour simply for aesthetic reasons.

Why is my bread moldy?

Believe it or not, mold is actually a type of fungus and belongs to the fungus family. As I'm sure you know, there are hundreds of different types and species in the fungi family, as well as mold. When mold develops, it turns into a colony of spores and so the fungus continues to grow.

Mold often starts out as small white spots and then over time grows larger, fluffier and slightly bluer or lighter green in colour.

Mold can form on artisanal bread when bread is stored in humid conditions, especially when stored in a plastic bag or container as these retain moisture. Spores develop and live on the moisture on the bread, and bread mold slowly breaks down the nutrients in the food and can grow from there.

Spores can travel through the air within the wrapper, meaning mold can spread from one part of the bread to another part of the bread, leaving the mold in random spots.

Heat, humidity and light are bad for bread and will help the spores to grow faster. To prevent white mold from growing on bread, it's best to store it in a cool, dark place.

How do I know what the white stuff on my bread is?

It can be a difficult challenge to tell if the white spots on the bread are flour, to emphasize how fresh and delicious the bread is, or if the white stuff on the bread is mold, to emphasize how old and ready for the bin is the bread.

Sometimes distinguishing between the two can be fairly easy, and other times it can be a bit more difficult. There are a few ways to check what the white stuff on the bread is:


Flour, since it's fresh, tends to be a bright, clean white color. On the other hand, mold is usually a duller, dirtier shade of white and can appear slightly grayer. Eventually that white color turns to a light green color and at that point it's much easier to determine that those white spots on your bread are mold.

Appearance over a Few Days: As mold grows, it is easier to tell the difference between mold and flour if you examine it over a few days. Mold will continue to grow and slowly discolor while flour stays the same. If you notice changes in the white spots on your bread, then stay away!

location on the bread

Not only does the mold grow and the flour stays the same, but where the stains are on the bread can help you distinguish between the two. Bread mold can appear almost anywhere on your bread, and with sliced ​​bread you may find it in the crust as well.

Mold will happen to be everywhere, and sometimes it will form in multiple places. Flour is always primarily on the top of the load and if it is a freshly baked load there may be flour dust around the edges as well. When you cut the bread, you shouldn't actually find any flour anywhere except in the crust of the bread.


Like any moldy or moist food or object, moldy bread has a fairly musky, musty odor. The fresh, fluffy smell of bread is masked by a mustier smell. It's important to remember that smelling the white stuff on bread will help you figure out what it is, but if it's mold then inhaling the spores can be dangerous.

Is It Safe to Eat the White Stuff on Bread?

Of course, the answer to whether the white stuff is mold or one of the molds variestypes of flour. After using the method above to try to distinguish what's on your bread, it's useful to know if you can then eat that.

As expected, flour is perfectly fine to eat. Bakers wouldn't dust their sourdough bread with it and use it as a base ingredient in their dough if we couldn't eat it. While inhaling raw flour might seem strange, you actually don't really notice it on the bread. If the white stuff turns out to be flour, don't hesitate to eat it up!

Whilecertain molds are perfectly safeto eat and may actually be the staple of certain foods such as blue cheese, but this is not always the case. Both health experts and scientists have warned that eating moldy bread can be very dangerous.

It's not possible to know what type of bread mold will grow on your bread, so the safest option would be to assume the mold is inedible.

Because bread is a soft food, the spores can easily develop and the roots of the fungus can grow deep into the bread, so even if you cut off and discard the visible white spots, you won't be able to eat the rest of the loaf should whole thing.

The Dangers of Mold

Mold can cause allergic reactions that result in sneezing, nasal congestion, sore throat and coughing. It can also cause people to have breathing problems, which can get worse with more exposure to mold or in people who already have allergic reactions to mold.

Final Thoughts

The white spots on your bread can really make or break the loaf. If the white stuff is flour, it probably means you have nice, fresh bread that smells and tastes wonderful. However, if the white spots on your bread turn out to be mold, you should keep your hands off it.

You can tell the two apart by color and watch out for possible developments. Inhaling or eating mold on bread can be very hazardous to your health, so once moldy bread dispose of it as soon as possible.

To avoid this and keep your bread fresh, store it in a cool and dark environment and hopefully you never have to worry about the question "what is the white powder on bread?".
