Why does bread go mouldy?
Bread goes moldy for a number of reasons. When the moisture from the bread (trapped inside of the bag) is mixed with the heat of the room, along with the yeast that was used to make the bread (and the yeast that naturally occurs), mold spores starts to multiply. You may notice that when you leave bread on the counter without any wrapping it simply dries up or conversely when you store your bread in the refrigerator it doesn’t mold (or at least for a very long time). The main requirements for mold to grow on bread are: moisture, food (nourishment), heat and time. There are a lot of air borne mold spores around us all of the time, not all of them are bad. Hope this helps.
