Molds in bread and baked goods can produce toxins that cause illness, according to Foodsafety.gov. Such foods should be discarded immediately at the sight of mold, as porous foods may be contaminated below the surface.Continue Reading
While some molds cause minor allergic reactions and respiratory issues, others produce harmful substances known as "mycotoxins" that result in more severe sickness, explains the USDA Food Safety and Inspection Service.
In contrast, foods like hard salami and dry-cured country hams, hard cheese and firm fruits and vegetables with surface mold are safe, though the moldy parts should be cut off completely prior to consumption.Learn more about Food Spoilage
In many cases, white bread goes moldy faster than whole wheat bread does. However, storage, preservatives and brand can play a role in how long it takes for mold to form on bread.Full Answer >
According to the MadSci Network at Washington University, the type of bread that grows mold the fastest depends on the “water activity” present in the bread. The water activity is what helps scientists to determine the shelf life of a product.Full Answer >
Bread with high moisture content grows mold the fastest. Thus, dark bread like rye, bran, oat and Boston loaves develop mold much faster than dense and dry variants. Moisture in the environment also plays a critical role in how quickly mold spots develop on any type of loaf.Full Answer >
Because mold spores occur naturally, all one has to do to make a piece of bread turn moldy in theory is to simply wait for it to grow mold, though it is possible to use bottled mold spores to accelerate the molding process. However, some breads made with artificial or natural preservatives may not mold as quickly as those bread products that are made without preservatives, so using a preservative-free bread may result in more successful mold growth. The bread mold experiment is a common simple science experiment for children who are learning about the scientific method, particularly the process of making a hypothesis.Full Answer >
