There are ingredients, known as texture ingredients, that cause liquids that normally don’t mix, to mix and become a stable mixture. These ingredients are called emulsifiers.

Trial 1: Add molecule 5 and molecule 6 in the dish. Are they attracted to one another and mix?
A) They are attracted to one another and mix
B) They are NOT attracted to one another and DO NOT mix
Trial 2: Add molecule 5 and molecule 6 in the dish. Now add the emulsifier molecule. Mix them with the help of an emulsifier. Are they attracted to one another and mix?
A) They are attracted to one another and mix
B) They are NOT attracted to one another and DO NOT mix

A) Yes they are mixing
B) No the are not mixing
How can you tell?
A) Molecule 1 and Molecule 5 are attracted to each other
B) Molecule 1 and Molecule 5 are not attracted to each other
This picture shows what happened when a food science mixed two substances together, then added something else. What did the food scientist add?
