From the following which is not an emulsifer?
From the following which is not an emulsifer?
- A. Agar
- B. Milk
- C. Gum
- D. Soap
Step-by-step solution
Agar is a gelling agent derived from seaweed, primarily used as a thickener or solidifier. It does not possess the amphiphilic properties typical of emulsifiers like milk proteins, gum arabic, or soap. While it can stabilize emulsions by increasing viscosity, it is not classified as a true emulsifier. In contrast, milk proteins (casein), gums (e.g., gum arabic), and soaps are well-known emulsifiers due to their ability to reduce interfacial tension between immiscible liquids.
