Why Does Swiss Cheese Have Holes Coriander Queen Now, the afp reports that scientists have debunked a popular theory and discovered the real secret behind swiss cheese’s holes — hay particles in milk. though urban legend has it that mice eat. As the cheese ferments, this bacteria creates carbon dioxide, which turns into bubbles. when these bubbles pop, they form holes. in the cheese world, these holes are known as “eyes.”. the size of the eyes are determined by the temperature, storage, time, and acidity levels in the cheese. so the longer the cheese is fermented, the bigger the.
Why Does Swiss Cheese Have Holes Coriander Queen What makes swiss cheese “holey” is additional bacteria called propionibacterium freudenrichii subspecies shermanii – p. shermanii for short. under the specific conditions that swiss cheese is made, the p. shermanii produce a gas: carbon dioxide. because swiss cheese is made at a warm temperature – around 70 degrees fahrenheit – the. The temperature and duration of cheese aging play crucial roles in the formation of holes. the ideal temperature for the growth of propionibacterium freudenreichii is between 20 25°c (68 77°f). at lower temperatures, the bacteria grow more slowly, resulting in fewer and smaller holes. the aging time also affects the size and number of holes. Actually, swiss cheesemakers add a bacterium called propionibacterium freudenreichii (subspecies sherminii) to the milk during production. this bacterium converts the lactic acid produced by the starter cultures into carbon dioxide, propionic acid and acetic acid. consequently, the carbon dioxide forms the eyes in the cheese and the other 2 by. The size and distribution of the holes depend on factors such as the type of pab used, the duration of aging, and the temperature at which the cheese is stored. the formation of holes in swiss cheese is a complex and fascinating process that involves the intricate interplay of propionic acid bacteria, carbon dioxide, and the cheese’s.
