white powder

Uses:

In the food industry, proteinase K is used to improve the flavor and texture of foods such as cheese, yogurt, and beer. It is also used to hydrolyze proteins in food production to improve digestibility.

In clinical diagnostics, proteinase K is used to digest proteins in serum, urine, and other bodily fluids. This enzyme is used to expose antigenic sites on proteins, which are then used to detect the presence of certain diseases.
