Why does food mold

Mold spreads quickly in fruits and vegetables. To save the product, cut off at least 1 inch around and below the mold spot, keeping the knife out of the mold to prevent cross-contaminating other parts. After trimming off the mold, re-cover in fresh wrap. Molds on Food: Are They Dangerous? All rights reserved. The University of Minnesota is an equal opportunity educator and employer. It's not super dangerous though you don't want to eat it!

So, you really want to toss any moldy food to be safe. You also tend to see it on fruits, vegetables, cheese, yogurt, and sour cream," says Amidor. And foods that contain any kind of water or fluid are susceptible to mold growth, as molds and fungi thrive in a dark, moist environments.

Mold can start developing in as soon as 24 hours, especially if the food is a few days old," explains Michalczyk. Foods like cheeses, mushrooms, breads, meat or fish, and milk are very susceptible to mold, she adds.

It depends on the type of food and where the mold is. For instance, "when mold is on harder fruits and vegetables, those roots of the mold cannot get deep into the food. That is why you can cut around it," says Amidor.

Unlike plants, molds and other fungi have no chlorophyll and can't make their own food. The molds that grow in your mold terrarium feed on the bread, cheese, and other foods. A mold produces chemicals that make the food break down and start to rot. As the food is broken down into small, simple parts, the mold absorbs them and grows. It can be annoying to find moldy food in your refrigerator. But in nature, mold is a very useful thing. Mold helps food and other materials rot, which is an icky but necessary thing.

In a natural environment, rotting things return to the soil, providing nutrients for other living things. Mold is a natural recycler. There are thousands of different kinds of molds. One mold that grows on lemons looks like a blue-green powder. A mold that grows on strawberries is a grayish-white fuzz. A common mold that grows on bread looks like white cottony fuzz at first. If you watch that mold for a few days, it will turn black.

The tiny black dots are its spores, which can grow to produce more mold. Why didn't some foods get moldy? If you used foods that contain preservatives, mold may not have grown very well on them. If you want to experiment more with mold, you can make one mold terrarium using food with preservatives like a packaged cupcake and another using food that doesn't have preservatives like a slice of homemade cake. Eating moldy food can cause serious health problems and should therefore be thrown away as soon as possible.

Mold spores lie dormant on almost all surfaces. When they land on a surface with the necessary environment, however, they will germinate and produce more spores.

Food is a perfect breeding ground for mold as it is inherently high in nutrients. Even fresh food hosts mold spores. These do not become visible until the food is a little older and the mold spores have had a chance to germinate. Once they germinate, mold will start to appear.
