Crystal formation in cheese can create a number of challenges for both natural and processed cheese manufacturers. Stated simply, crystals in cheese occur when the concentration of a product (such as a salt like calcium lactate or an amino acid like tyrosine), exceeds the maximum solubility within the moisture phase of a cheese. Crystal formation in cheese can create a number of challenges for both natural and processed cheese manufacturers. A desired attribute in hard Italian cheeses, consumers often look for these gritty white crystals as the sign of a properly aged cheese. That being said, not everyone’s freezer is 100 percent consistent, and the temperature can fluctuate if you’re opening the door a lot, or if you live in an area that frequently loses power. However, in some cheeses, like industrial cheddar, they are considered a production defect. Calcium oxalate crystals can also form in the bladder causing problems for your pet.

The grains you are noticing are crystals of either calcium lactate or the amino acid tyrosine. Therefore, while these amino acid crystals don’t have much of their own flavor, they can signify a well-aged cheese that should have rich, complex flavors. Cheese makers like to use this bacterium since it gives their cheese a unique flavour. Steps that are often taken to avoid this defect include: avoiding excessive lactate levels in cheese (such as washing or rinsing the curd), removing more calcium during cheese manufacture (thus less is left in cheese to form crystals), tight packaging of cheese and avoiding conditions that cause cheese to release moisture (low pH, warm temperatures including heat generated by light exposure).  In addition to these known solutions, the Wisconsin Center for Dairy Research has also been investigating the potential use of membrane filtration to help control this issue.
