What is homogenised milk?

Through the process of homogenisation, the milk fat globules that make up the cream are broken down into a smaller and more uniform size, preventing them from rising to the top again. Instead, they remain within the body of the milk. There are two stages involved in homogenising milk. In the first, milk is pushed through tapered tubes.
