Protein: foam formation
A foam forms when small bubbles of gas are trapped in a solid or liquid.
Protein: gluten formation
Wheat and other related grains (including barley and rye) contain a mixture of two proteins glutenin and gliadin. When flour made from grinding these grains is mixed with water the two proteins combine to form gluten. Without water, gluten is not formed.
