Casein is a complex protein that is naturally present in milk and is responsible for the milk's ability to coagulate. As the bacteria metabolize casein, they release various enzymes, including proteases. These proteases have the ability to cleave the large, complex casein molecules into smaller peptides and amino acids.

The breakdown of casein is a critical step in the development of the orange color. As the bacteria work on the milk proteins, they create a unique chemical reaction. This reaction involves the formation of amino acids and the release of small peptides. One of the resulting peptides, called casokinase, is particularly interesting. Casokinase has a unique property; it can oxidize certain amino acids, particularly tyrosine, into a compound known as tyrosinase. This tyrosinase then catalyzes the oxidation of another amino acid, phenylalanine, to produce a compound called phenol.

The presence of phenol is a key factor in the orange color of Cheddar cheese. Phenol is a naturally occurring compound that can be oxidized further by the bacteria. This oxidation process leads to the formation of various pigments, including carotenoids. Carotenoids are pigments that give certain fruits and vegetables their vibrant colors, and they are also responsible for the orange hue in Cheddar cheese. As the bacteria continue to break down the milk proteins, they create an environment that promotes the production and accumulation of these carotenoid pigments, resulting in the characteristic orange color.

This microbial activity is a natural and intentional part of the cheese-making process. The bacteria cultures are carefully selected and controlled to ensure the desired flavor, texture, and color development. The orange color of Cheddar cheese is a testament to the intricate relationship between the bacteria, the milk proteins, and the chemical reactions that occur during the maturation process.
