Well, even if you have never tasted the Swiss cheese you must have seen one in the supermarket or on television for instance. Its look is so captivating that it’s hard not to notice it. You may wonder why this cheese has these mysterious and grand holes in its structure. Well, here is the answer to your question. The holes are not there by accident, Swiss cheese belongs to the species that has holes in itself, which are known as the eyes.
People around the world have always been wondering why the Swiss cheese has a familiar characteristic appearance. Its distinctive features have always been small holes found within the cheese. It turns out that its holes are precisely the reason that is crucial for its production and that makes this cheese so specific and interesting in its appearance. Dr. Michael Tunick, the author of the video “Science of cheese,” explains the reason why these holes are made.
The occurrence of holes in some cheeses is not accidental, but is due to the presence of microparticles of hay in milk, – experts from Agroscop say.
They point out that by dosing the particles, dairy farmers can control the number of holes in the cheese.
The type of bacteria in cheese produces something called propionic acid. It also produces carbon dioxide gas, and these small bubbles of the gas are accumulating.
Since it has not completely solidified, the eyes are formed within the cheese. There are also some varieties that are intentionally made to have these holes, according to the businessinsider.com.
Gruer is another type of cheese that has holes in its structure, and many others have something similar to small slits. They are also very popular and tasteful. The cheese without holes is in the professional circles known as a “blind” cheese.
