In the mammalian process of lactation, a special class of milk-secreting cells referred to as mammocytes.Line up single layer around pear shape alveoli. Cells absorb all of the building blocks of milk, next synthesis little drops of fat on a structure called the smooth endoplasmic reticulum. 

The droplets combine and other molecules and store between in spaces between cells. Mammary glands in the end secreted the milk through the breast or via tubes inside the abdomen.

After buying from the store, we heat the milk for few minutes but milk is already pasteurised before coming out in the market.It is a treatment where heating milk to kill the microorganisms, bacterias to keep it safe. It heats for the temperature of 71.7°C, at least 15 seconds. It quickly cooled less than 3°C. Milk could be processed to further to transform it into the dairy products with longer shelf life and cheese, butter, ghee come out.

  • Homogenization

It is a process to force the milk at high pressure through small gaps. It offers milk it’s white in colour. It reduces the size of fat globules means particles into a smaller size. To stop the separation of the fat from the water, homogenization aids.
