Emulsion and Emulsification Technology

Emulsion is one of the most common products in our lives and used to manipulate biological systems in nature and our bodies. This chapter introduces basic concepts of emulsion, for example, definition, classification, relation with surfactants, disruption process, and will give hints how to prepare a stable emulsion. The most important term on emulsion is “non-equilibrium,” which allows us to distinguish from the other solution states and help us to understand why emulsion technologies are so complicated that any beginner cannot simply find a way to form a stable emulsion. In addition, this chapter shows as many emulsification technologies and their fundamental theories as possible.
