When reaching for a loaf of bread to make a sandwich, you might notice some odd white patches. So, what is white stuff on bread? If you notice any white stuff on bread, be sure to check it out because depending on closer inspection it could be mold or flour.

While spots of flour on bread are safe to eat, mold is not. Eating mold can make you sick and can even cause health problems. It is important to be able to properly identify the white stuff on bread to ensure that it is safe to eat.

What Is The White Stuff On Bread?

The white stuff you see on bread could be two different things: flour or mold. While flour on bread is safe to eat, mold, on the other hand, is not. It is important to be able to safely distinguish the two so you know whether you can eat your bread or if you should throw it out.

Mold

Though many people associate mold with being green, it can also be white. Mold may start out as small white spots that grow into larger spots that are fuzzy with hints of green and blue.

You will also notice that mold will have an unpleasant smell. The white is often a dirty white that may include splotches of green, blue, or even gray. Though some mold may have a smooth texture, it is common for it to have a fuzzy appearance.

Within a couple of days, the mold will continue to grow and spread on your bread. It will likely begin to change colors over time as well.

Flour

Oftentimes, artisan bread will have flour dusted on it. The flour on your bread is completely safe to eat and is nothing to worry about.

Flour has a smooth texture and is a brighter white than mold is. It will not have any other colors throughout it, it will only be white. Flour on bread will simply just smell like bread, it doesn’t have a distinct smell like mold that will set it apart from the smell of bread.

Flour may be on both the top and bottom of the bread. Though not all bread will have flour sprinkled on it, there are many loaves of bread that do. It is particularly common on bread that comes from bakeries.

Why Does Bread Have Flour On It?

There are a few reasons your bread may have floured sprinkled on it. Though most name-brand varieties of bread will not have flour sprinkled on them, a lot of freshly baked bakery bread will.

Prevents sticking

It is not uncommon to use flour when making and baking bread to prevent sticking. Bakers will also often coat their hands with flour while working with the dough to prevent sticking. The flour that is sprinkled on the bread during this process sometimes will remain on after packaging.

Gives a rustic appearance

Artisan bread often has flour sprinkled on it to give it a rustic appearance. Though sprinkling flour on bread doesn’t necessarily do anything for flavor or texture, it gives bread an aesthetically pleasing look.

Can be used to distinguish different loaves

In some bakeries, bakers may sprinkle flour on bread to create different shapes and patterns. This can be done to help distinguish different types of loaves from each other.

What Causes Mold on Bread?

There are a few different reasons why mold may grow on your bread. The most common reason that cause it to happen is that bread was exposed to a warm, moist environment. Warm temperatures and moisture with limited airflow will often result in moldy conditions.

Moisture

Bread naturally contains moisture and when not properly stored, the moisture in the bread can cause mold. In addition, exposure to excess moisture, especially from humidity, mold growth can happen sooner and spread faster.

Be sure to store your bread in a cool, dry environment to prevent the growth of mold. Store your bread in a paper bag, a bread box or an airtight container.

Temperature

Temperature is another big factor in the cause of mold growth. Mold strives in temperatures between 77 to 86 degrees Fahrenheit.

For best results, store your bread in temperatures 70 degrees and below. If the temperatures are too warm and humid, you can store your bread in the fridge or freezer.

To store your bread in the freezer, wrap it in a layer of plastic wrap and a layer of aluminum foil. For storebought bread, you can put it in the freezer in a bag that it came in.

To defrost, you can place your bread on the countertop for around one to two hours or you can thaw it overnight in the fridge. In addition, you can also defrost it by heating up slices for around 15-30 seconds in the fridge.

Making Sure Your Bread Is Safe To Eat
