Is molding food a physical change?
Bread molding–Don’t get confused, but there are two chemical changes going on here. Mold, a living organism, is consuming the sugar, water and minerals in the bread. And the bread is decomposing. These changes are irreversible, release smelly gases and produce a small amount of heat.
What kind of change is molding?
The size or shape of matter often changes, but there is no chemical reaction. Phase changes are physical changes. These include melting, boiling, vaporization, freezing, sublimation and deposition. Breaking, crumpling, or molding matter also results in a physical change.
What is molding cheese?
Mold Is Used to Make Certain Foods Penicillium is a genus of molds used in the production of many types of cheese, including blue cheese, Gorgonzola, brie and Camembert ( 2 , 7 ). The strains used to make these cheeses are safe to eat because they cannot produce harmful mycotoxins.

What’s the best way to make a cheese mold?
You can make a homemade cheese mold. We suggest using a hot nail for the holes, to seal the plastic, easier to sanitize. Also, a round mold is better than square since the surface to mass ratio is lower. The corners of square molds tend to dry out faster. One other consideration is whether the plastic is food grade.
What happens if you put PVC in a cheese mold?
The acidity from the draining when will leach the plastic into your cheese. If you made a cheese mold with PVC, this ‘odd flavor’ is from the plastic in your mold. We strongly advise not using PVC for any cheese making. Since you are working with an acidic food, leaching of unknown elements is very probable.
How does the blue mould work to make blue cheese?
As the blue veins develop they enhance the flavour of the cheese. Penicillium roqueforti itself (and the enzymes it releases) aggressively breaks down the fat and protein in the cheese to give the texture, flavour and aroma associated with blue cheese: sharp, strong and piquant. So how does the blue mould work to make these flavours?
Is it safe to eat cheese with mold in it?
Of course, not all molds pose a risk. Some types of mold are used to make cheeses, such as Brie and Camembert. These molds are safe for healthy adults to eat. However, these cheeses, as well as other soft cheeses and cheeses made with unpasteurized milk, are best avoided by people…
Why do some cheeses have mold in them?
Some cheeses have mold introduced to help create a protective rind, and others like blue are spiked with stainless steel rods to infuse the mold deep into the cheese. Below are some of our favorites:

How big should you cut off moldy cheese?
Cut off at least 1 inch (2.5 centimeters) around and below the moldy spot. Be sure to keep the knife out of the mold, so it doesn’t contaminate other parts of the cheese.
How is cheese pressed to the final shape?
Pressing is the process of molding the cheese into the desired final shape. Usually it is either pressed into a wheel or a block. Most of the time, pressing is accomplished by placing the curds into a mold and using a cheese press to squeeze whey out.
