Crystallization is a significant process employed to produce a wide variety of materials in pharmaceutical
and food area. The control of crystal dimension, crystallinity, and shape is very important because they will
affect the subsequent filtration, drying and grinding performance as well as the physical and chemical properties
of the material. This review summarizes the special features of crystallization technology and the preparation
methods of nanocrystals, and discusses analytical technology which is used to control crystal quality and performance.
The crystallization technology applications in pharmaceutics and foods are also outlined. These illustrated
examples further help us to gain a better understanding of the crystallization technology for pharmaceutics
and foods.
