After you've heated a glass of milk or Hot Chocolate, sometimes the milk forms a skin on top of the liquid. The skin is comprised of solid proteins that combine with the milk's fat molecules, which begin to evaporate as the milk is heated. These proteins, casein and beta, clump together when the liquid reaches a temperature of around 113 to 122 degrees Fahrenheit (45 to 50 Celsius). As the heating continues, the soft protein layer begins to dry out, which is why the milk forms a skin on the liquid's surface. This layer of skin forms a hard barrier, causing steam to build up beneath it and increase the liquid's temperature. When left alone, this often causes the milk to boil over.

What is the process for creating milk skin when making traditional custard desserts?
Milk skin is created when milk is heated and a thin layer forms on the surface. In traditional custard desserts, this process involves heating milk, sugar, and other ingredients until the mixture thickens and a skin forms on top.

What is the skin on milk when it is boiled?
It is proteins from the milk that have become "sticky" from being heated and bond together to form a thin layer of protein on top of the milk. Apparently keeping the milk below 158 degrees Fahrenheit and using a lid can prevent this film from forming.
What is milk scum?
Nata? It's called 'the skin' and its made up of solid proteins that combine with the milk's fat molecules, which begin to evaporate as the milk is heated. These proteins, casein and beta, clump together when the liquid reaches a temperature of around 45 to 50 degrees Celsius. As the heating continues, the soft protein layer begins to dry out, which is why the milk forms a skin on the liquid's surface. This layer of skin forms a hard barrier, causing steam to build up beneath it and increase the liquid's temperature. When left alone, this often causes the milk to boil over. Though milk forms a skin when heated in most cases, there are several ways to prevent this skin from forming. If you plan to heat the milk over the stove, frequent stirring will break up the protein and fat molecules, so that the membrane will not develop. If you are heating milk in a microwave, you can place a wax paper lid known as a "cartouche" on top of the container, which will slow the evaporation process and maintain the milk's liquid form. The milk forms a skin only on heated milk that contains fat. If you are heating skim milk, there is no danger of a skin forming on top. Because skim milk contains no fat, the protein molecules have nothing to bond with, and are unable to coagulate. Source(s): milk /hot chocolate /coffee lover
Why should a skin that forms over heated milk be stirred back into the milk?
It is up to you. Some people actually scoop up the skin and either dispose of it, or even eat it (it is still milk, after all). If stirred back in, it may make the rest of the milk rather lumpy.
What does milk do if not stirred when heated in a micorwave?
Good quality milk will not curdle when boiled. It can be used as a test to determine how heat stable the milk is before heat treatment. Ie, if it curdles, don't use it as it would foul the equipment.
A solid layer that often forms on the surface of milk during heating is called?
a skin
What happens when you boil milk?
When you boil milk, the heat causes the proteins in the milk to denature and the fat molecules to separate. This can lead to the formation of a skin on the surface of the milk and can also cause the milk to overflow if not watched carefully.
