At the end of this module, you will be able to:
In this module, we will examine the ice crystallization process. You will learn about the formation of nuclei and crystal growth and how to obtain small ice crystals during freezing. In the first video, you will learn about the nucleation process and homogenous nucleation.
In the following video, you will learn the factors that influence the nucleation process. The number of nuclei formed during this stage has an impact on the size of ice crystals later as the freezing process progresses.
After the formation of nuclei, the next stage in the crystallization process is the growth of ice crystals. In the following video, you will learn about crystal growth.
Frozen food quality is often associated with the size of the ice crystals. In the next video, you will learn about the ice crystal size and how to control it.
In this module, you learned the mechanistic steps involved in the ice crystallization process. You learned the role of nucleation and ice crystal growth on the number and size of ice crystals formed during the freezing process.
