Ice cream, also known as ice cream, is a sweet food made of frozen milk and one of the common foods in summer. In its simplest form, ice cream is a kind of cold food mixed with ordinary food (milk, cheese, cream, etc.). ) with some desserts and other seasonings. After mixing them together, it is necessary to lower the ambient temperature to a very low temperature to ensure that a softer form is formed instead of large ice cubes. Generally, industrially manufactured ice cream is made by injecting mixed ice cream liquid into a mold placed in a mixture of ice and salt.

In the process of melting, the mixture of ice and salt will absorb a lot of heat, so it is convenient to freeze the prepared liquid into ice cream. According to the American federal food law, the content of cream in ice cream is at least 10.
