A surfactant is the scientific name for an emulsifier, a.k.a. something that attracts both water and oil molecules and binds them together. These emulsifiers allow for the creation of a vinaigrette that is creamy and won’t separate—truly a beautiful thing.
Similarly one may ask, what emulsifies oil and vinegar?
An emulsion is simply a blend of two liquids that don’t normally bind together, such as oil and vinegar. You do this by adding the oil to the vinegar or other liquid in a slow and steady stream while furiously beating with a whisk or blender.
Beside above, what happens when you mix oil and vinegar? Oil and vinegar do not mix or even if they are mixed they will quickly separate when given the opportunity. Some proteins such as eggs are emulsifiers that will cause oil and vinegar to mix.
Furthermore, how do you mix oil and vinegar?
That’s because oil and vinegar don’t naturally mix. No doubt you’ve seen this yourself—shake up a bottle of salad dressing and the two parts come together. Set the bottle down and in seconds, they start to separate again until all the oil is at the top and all the vinegar is at the bottom.
Is Vinegar an emulsifier?
A good emulsifying agent will keep the oil and vinegar mixed together, delaying the appearance of a clear boundary. Try variations with more egg white, or with other emulsifiers, such as egg yolk, balsamic vinegar instead of white vinegar, etc.
