As the white foam from the milk rises to meet the red/brown surface of the shot, a contrast is created and the design emerges. As the milk is poured, the foam separates from the liquid and rises to the top. If the milk and espresso shot are "just right", and the pitcher is moved during the pour, the foam will rise to create a pattern on the ...
The protein properties in milk are what create the foamy texture in frothed milk. Casein molecules (a type of protein) form the molecular structure micelle, which get broken up when air from a milk frother is introduced. The casein molecules gravitate to the air bubbles trapping the air and creating foam. [4]
At higher temperatures, the protein β-lactoglobulin enables the foam to maintain its structure and is the prime factor in the formation of foam. [ citation needed ] This can be shown trivially by adding various quantities of skim milk powder which contains a high concentration of β -lactoglobulin.
Foam fractionation is a chemical process in which hydrophobic molecules are preferentially separated from a liquid solution using rising columns of foam. It is commonly used, albeit on a small scale, for the removal of organic waste from aquariums ; these units are known as " protein skimmers ".
For proper foam formation, it is also important to dry the glass thoroughly after washing. Any water in the glass can prevent excitement of the gas by covering designs set in the bottom of the glass, thus making the beer flat. Conversely, some styles such as Belgian witbier benefit from being poured into a wet glass to control the often ...
