  • How is milk curd formed?

    Q: How is milk curd formed?

    A: Milk curd forms when milk curdles. During curdling, chemical processes cause casein, the milk proteins, to clump and form curds. People can deliberately curdle milk by using agents such as rennet, which is involved in the making of cheese, or acids, such as vinegar and lemon juice. Milk also curdles naturally when it spoils.
