Cheese crystals are a natural part of the aging process, although the cheese doesn't necessarily have to be aged for a long time. There are two types of cheese crystals: Tyrosine and Calcium Lactate. Tyrosine crystals form only in the interior of the cheese and are firm, bright white, and found in Swiss and Romano cheeses. Calcium Lactate crystals can form in both the interior of the cheese and on the surface. They are softer, paler, and appear more frequently than Tyrosine crystals.

Tyrosine crystals are firm, bright white, and found in Swiss and Romano cheeses
There are two types of crystals that can form in cheese: Tyrosine and Calcium Lactate. Tyrosine crystals are firm, bright white, and found in Swiss and Romano cheeses. They form only in the interior of the cheese.
Tyrosine is a non-essential amino acid that your body uses to create chemicals like dopamine. The crystallisation process begins when proteins, moving around in the serum or paste of the cheese, collide and form a nucleation site. This attracts more proteins, and the size of the crystals will grow.
Calcium Lactate crystals can form in both the interior of the cheese and on the surface. They are softer, paler, and appear more frequently than Tyrosine crystals. They are typically found in cheddar and Colby. However, both types of crystals can also appear alongside each other in certain cheeses like aged Parmigiano-Reggiano or Gouda.
Cheese crystals are a natural part of the aging process, although the cheese doesn't necessarily have to be aged for a long time. They are characteristic of many long-aged hard cheeses, including comté, aged cheddar, grana cheeses like Parmesan, Grana Padano, and pecorino romano, as well as old gouda. However, in some cheeses, like industrial cheddar, they are considered a production defect.

Calcium Lactate crystals are softer, paler, and found in cheddar and Colby
There are two types of crystals that can form in cheese: Tyrosine and Calcium Lactate. Tyrosine crystals are firm and bright white, and are found in Swiss and Romano cheeses. Calcium Lactate crystals, on the other hand, are softer and paler, and are typically found in cheddar and Colby. They can form in both the interior of the cheese and on the surface. Calcium Lactate crystals are the most common type of cheese crystal, especially in younger cheeses. They are a natural part of the aging process, although the cheese doesn't necessarily have to be aged for a long time. In some cases, Calcium Lactate crystals can appear alongside Tyrosine crystals in certain cheeses like aged Parmigiano-Reggiano or Gouda.

Crystals are formed when proteins collide and attract more proteins to the site
Cheese crystals are formed when proteins collide and attract more proteins to the site. This process is dependent on the kind of material (the types of proteins in a cheese) and the concentration of that material. The crystals are whitish, semi-solid to solid, slightly crunchy to gritty crystalline spots, granules, and aggregates that can form on the surface and inside of cheese. They are characteristic of many long-aged hard cheeses, including comté, aged cheddar, grana cheeses like Parmesan, Grana Padano, and pecorino romano, as well as old gouda. However, in some cheeses, like industrial cheddar, they are considered a production defect.
There are two types of cheese crystals: tyrosine and calcium lactate. Tyrosine crystals form only in the interior of the cheese and are firm, bright white, and found in Swiss and Romano cheeses. Calcium lactate crystals can form in both the interior of the cheese and on the surface. They are typically found in cheddar and Colby. These crystals are softer and paler than tyrosine crystals and appear more frequently. Both types of crystals can also appear alongside each other in certain cheeses like aged Parmigiano-Reggiano or Gouda.
Tyrosine is a non-essential amino acid that the body uses to create chemicals like dopamine. Calcium lactate crystals are especially common on younger cheeses and on the surface of cheddar. Depending on the cheese and its age, these crystals can consist of either or both enantiomers.

Crystals are a natural part of the ageing process
The crystallisation process begins when proteins, moving around in the serum or paste of the cheese, collide and form a nucleation site. This attracts more proteins, and the size of the crystals will grow. The likelihood of cheese crystal formation depends on the kind of material (the types of proteins in a cheese) and the concentration of that material.
Cheese crystals are characteristic of many long-aged hard cheeses, including comté, aged cheddar, grana cheeses like Parmesan, Grana Padano, and pecorino romano, as well as old gouda. However, in some cheeses, like industrial cheddar, they are considered a production defect. Cheese crystals can consist of different substances, depending on the cheese and its age.
While the cheese doesn't necessarily have to be aged for a long time, the crystals are a natural part of the ageing process. Tyrosine is a non-essential amino acid that the body uses to create chemicals like dopamine.
