Abstract:
Five chemical compounds (tyrosine, sorbic acid, calcium lactate, calcium phosphate and sodium chloride), which have previously been reported to occur as crystals on various cheeses, were induced to crystallize on the surface of mild Cheddar cheese, These crystals were observed and photographed, using scanning electron microscopy (SEM). The distinct features exhibited by the crystals of each compound demonstrate the potential use of SEM in identification of crystals on cheese as well as in studying the factors contributing to their formation.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
