Question: how lecithin works as an emulsifier?
Answer: Lecithin in Emulsions Lecithin makes a good emulsifier because the hydrophobic end dissolves in oil droplets and the hydrophilic end dissolves in water. In emulsions the only place lecithin likes to be is at the edge of oil droplets with its hydrophobic end in the oil and the hydrophilic end in the water.
