How does milk become ice cream?
Ice cream is cold. Ice cream is sweet. Ice cream is a yummy treat. But do you know how milk becomes ice cream?
On the farm
Cows need a lot of food and water to make milk. A healthy cow can produce about one hundred glasses of milk in one day! Yes, one hundred!
On the truck
Trucks pick up the fresh milk from farms. The trucks have huge tanks (罐) that keep the milk cold.
In the factory
Factory workers separate the milk into cream and skim milk. Then the cream and milk are put together with sugar and other things. This kills germs (病菌). Then the mix is cooled.
A machine whips (搅打) the mix. Then it is time to add flavourings (调味品), such as chocolate or vanilla (香草).
The ice cream is cooled again. This time, it becomes very hard. Do you want some ice cream?
