How is milk produced? On the farm, the milk yield is measured and the milk kept cool in a bulk storage tank. Road or rail tankers take the milk to the dairy, where it is pasteurised to kill off any bacteria. Pasteurisation involves heating the milk and then rapidly cooling it. Pasteurised milk is separated into cream, low-fat milk, and skimmed milk. Some is made into butter, yoghurt, and cheese. Long-life milk is made by the UHT (ultra-high temperature) process, which allows it to be kept for months. From milk, a range of dairy products are made, including cream, butter, yoghurt, and cheese.   Previous: Back Book: 1001 Section: Science and Technology Chapter: Fishing and Agriculture
