Cheesy Facts That Will Make You Hungry
—Jay Sailors
Cheese has been around for thousands of years, and today it can be served in almost any way—on pizza, in sandwiches, or just by itself. There's a wealth of interesting yet little known information about cheese. Here are some things for you to think about the next time you're enjoying this delicious dairy product.
Swiss cheese is a popular cheese that can be easily recognized from its holes. Curiously, those holes have become smaller and fewer, and some people wanted to know why. Searching for an answer, Swiss scientists found a new explanation for where the holes come from in the first place.
For around a century, people thought the holes in Swiss cheese were caused by bacteria. The idea is that bacteria release carbon dioxide inside the cheese, and this process created the holes. However, a new Swiss study found that the holes are actually caused by tiny pieces of hay. These pieces got into the buckets that were used to collect milk for making cheese. The holes are slowly disappearing because we now use milking machines and cleaner methods to collect milk.
起司已經存在數千年了，而今幾乎可以任何方式來食用：在披薩上、三明治裡或只單獨存在。起司有很多有趣但鮮為人知的資訊。這裡有一些讓你下次享受這種美味乳製品時可以好好想想的事。
瑞士起司是一種從孔洞就能輕易辨識的熱門起司。奇特的是，那些孔洞變得愈來愈小也愈來愈少，有些人想知道為什麼。瑞士科學家尋找答案時發現了一個起司上的孔洞最初從何而來的新解釋。
大約一百年來，人們認為瑞士起司上的孔洞是細菌造成的。這個看法是細菌在起司裡面釋放出二氧化碳，而這過程產生了孔洞。然而，一項新的瑞士研究發現孔洞事實上是細小的乾草屑造成的。這些碎屑掉進用來收集牛乳以製作起司的桶子裡。孔洞慢慢消失是因為我們現在用擠乳機和更乾淨的方式來收集牛乳。
