How Emulsifiers Work
Emulsifiers are molecules that have both a hydrophilic (water-loving) and a hydrophobic (water-hating) end. This unique structure allows them to interact with both water and oil or fat, such as fatty acids, creating a stable mixture that prevents the ingredients from separating.
For example, in salad dressings:
The hydrophilic end of the emulsifier molecule interacts with the vinegar
The hydrophobic end interacts with the oil
This creates a homogenous mixture that stays together.
Understanding the science behind emulsifiers allows you to value their significant contribution to the texture and consistency of popular foods.
