Main Chemicals, Compounds, Components
Sugar and Milk are the two main ingredients of ice cream.
Sugar’s (fructose) molecular structure is C6H12O6
Milk does not have a fixed molecular structure. It is an emulsion or colloid of butter-fat molecules within a water-based fluid. These particles are made of phospholipids and proteins. There are too many components in milk to have a basic chemical formula so it is just a very complex mixture.
Chemistry's Role
Both are naturally occurring ingredients.
Sugar comes from sugar cane plants.
Milk comes from dairy farm cows.
Ice cream is made artificially.
Background Research
Ice cream dates all the way back in print to 1744. A man named Thomas Black from Virginia sampled it as a guest of Governor Thomas Bladen of Maryland.
The first ice dessert was probably prepared for the Roman emperor Nero Claudius Caesar during the 1st century A.D. It was made from snow and fruit juices and other flavorings. After the decline of Rome the technique for making ice desserts seems to have been lost.
