Now the milk is ready to be packaged by automatic machines. These fill and seal the cartons very rapidly. The cartons are now placed in crates and shipped to stores or restaurants in special refrigerated trucks. Even in the grocery store you will see that the packaged milk is not left out on the shelf, but is put into a special cabinet or refrigerator to keep it cool and delicious. Not all milk is sold as milk.
Milk is used for making ice cream, butter, cream, sour cream, and yogurt.
Here, milk is being changed into cheese. It is put into a large vat and cooled. A special bacterial culture and rennet are added. The cheese is then cooked, drained, pressed, and allowed to ripen. Salt will be added to this and the cheese will be shaped into one of the big wheels found in cheese shops or the wheel of cheese may be cut into wedges.
