Most commonly found are calcium lactate crystals, especially on younger cheese, on the surface, and on cheddar. It precipitates out as crystals as the cheese loses moisture, rather in the same way that crystals form in a sugar water solution as it cools down. Iodized salt can also slow the aging process drastically. There are other components in the cheese moisture phase (e.g., phosphates) that can also bind soluble calcium, so sometimes calcium lactate crystals are not observed even though it may appear that the concentrations of calcium and lactate should be high enough for crystal formation. But, food in a freezer rarely gets to that point, with a couple exceptions.

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.
