Most of the time, you don’t even need to scrape the spot. Inspecting the appearance lets you decide what it is. It’s easy to differentiate between these two things.

In most cases, there are differences in colors. You’ll notice the mold is dull and dirty white. On the other hand, flour has a bright white color. When you see any greenish-blue hue, it must be moldy.

After a couple of days, the color of the spot will change. It’s just flour if the color does not change over time.

3. Check the odor

Sometimes, bread has a very bad smell. It’s musty and unpleasant. Mold has an odor that makes you clear how bad this bread is for you right now.
