1. Cheese is a kind of food made from milk or other dairy products through processing and fermentation. It is a widely used food all over the world. It can be used to make various foods and dishes, and can also be eaten directly.
The history of cheese can be traced back to ancient times. According to the research of archaeologists, the origin of cheese can be traced back to the Middle East in 5000 BC. At that time, people began to raise cattle and sheep and store milk. Because milk is easy to deteriorate during storage, people began to look for ways to extend the shelf life of milk. They found that cheese made from milk can be preserved better and the taste of cheese is richer.
3. The process of making cheese is relatively complicated, but it can be basically divided into several main steps. First, milk is heated to a certain temperature to kill potentially harmful bacteria. Then, add enzymes or acids to promote the milk to coagulate into lumps. This process is called condensation. Next, the curd will be cut into small pieces, heated and stirred to further separate whey and solid components. Finally, the solid ingredients will be squeezed to remove excess water and form the shape and texture of the cheese.
