Cows are milked on farms and the raw milk is cooled and stored in tanks. It is then transported to a milk processing plant. At the plant, the milk passes through clarification to remove impurities. It is then pasteurized by heating to 72°C to kill bacteria, homogenized by breaking up fat particles, and fortified with vitamins A and D. Finally, the milk is packaged into containers like cartons or bottles and delivered to stores.

5. AT THE PROCESSING PLANT…
The milk passes through a clarifier:
The milk is spined at high speed to remove
•any dust
•dirt participles
• bacteria
The milk is fortified, pasteurized and homogenised

6. The milk is FORTIFIED
Vitamins A and D are added to the milk

8. In the HOMOGENISING process,
Milk fat particles are broken up
Then, they are mixed into the rest of the milk.
