Lecithin powder is a mixture of glycerophospholipids involving phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidic acid. The main sources of lecithin powder are egg yolk, marine sources, rapeseed and sunflower oil. It is a remarkable emulsifier and has low solubility in water.

Lecithin powder is utilized as an anti dusting agent. Lecithins decrease static electricity by wetting dusty particles. In the paint industry, it produces protective coatings for surfaces with painting and printing ink. It has also antioxidant properties, assists as a rust inhibitor. Moreover, lecithin powder used as different agents such as color-intensifying agents, conditioning aid modifiers, and dispersing aid.

Lecithins decelerate nucleation in fats and even monoglycerides, decreasing graininess in texture. Lecithins are most often utilized as an amphoteric emulsifier and they promote the stable formation of oil-in-water and water-in-oil emulsions by reducing the interfacial surface tension between immiscible liquids. Lecithin is a source of choline due to it contains phosphatidylcholines.

Lecithins powder helps in mixing the ingredients by decreasing time and increasing efficiency of mixing of unlike ingredients, for instance, sugar and shortening by providing lubricity as well as viscosity reduction at the contact surfaces of the incompatible solids. It reduces fat and egg requirements in doughs and baking. It also helps even out the distribution of ingredients in the dough, stabilizes fermentation.

Lecithin acts as a releasing agent and provides easy release from metallic surfaces by attaching to the metal surface during hot or cold cooking. They assist in the cleaning of hot surfaces where proteins or batters are applied. They also decrease sticking between frozen food products.
