Why Is Lecithin a Good Emulsifier? | LIVESTRONG.COM

https://www.livestrong.com › Food and Drink
Oct 3, 2017 - 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. If you think of a party balloon ...

https://s3-us-west-2.amazonaws.com/adms3/.../Lecithin/Lecithin-as-an-Emulsifier.pdf
ADM Lecithin. As an emulsifier, soy lecithin is used in food applications as an aerating agent, viscosity modifier, dispersant and lubricant. Typically, an emulsion is a suspension of small droplets of one liquid in another liquid with which it is incapable of mixing. Oil-in-water (O/W) and water-in-oil (W/O) are the two pri-.

In some cases, crystals are something you try to develop; in others, they are something you try to avoid. It is important to know the characteristics and quality of the crystals in different food. Butter, margarine, ice cream, sugar, and chocolate all contain different types of crystals, although they all contain fatcrystals.
