1 Lecithins and Phospholipids A Simple Guide to Use and Selection ALC. About Lecithins Lecithins are prepared by extracting and purifying Phospholipids from naturally occurring products such as soybeans, eggs, sunflower and canola seeds. Lecithins are amphiphilic (they have different affinities for oil and water), and their low production costs make them invaluable in a broad range of manufacturing processes. Lecithins help make chocolate American Lecithin Company Natural and Organic Lecithin smooth and powdered baby offers a wide range of Lecithin is the unique all-natural emulsifier.

3 How Lecithins Work Lecithins are used mainly as emulsifiers. They are surface- in dip tanks and spray active; simultaneous hydrophilic (water-loving) and applications. Water-filled dip tanks usually contain up to hydrophobic (water-repelling) properties enable Lecithins to 10% de-oiled Lecithin ; pan make stable blends of materials that otherwise do not mix or belt-release applications easily and tend to separate. The amount of Lecithin needed consist mainly of vegetable to blend substances such as the soybean oil and water in oil with approximately 2%.

Lecithins also have characteristics that help: products such as processed Lecithin with the amylose cheese slices, Lecithins help Disperse and suspend powders into liquids portion of wheat flour slows form a stable film barrier Control the viscosity of liquids and semi-liquids starch retrogradation. that prevents them from This process in effect extends Prevent foods from sticking to contact surfaces sticking together.

Prevent adhesion of food products to one another directly in products such as baked goods, they enhance Nutritional Supplements the ability to cut and shape Lecithins have nutritional products and reduce sticking Lecithins can be: fat powders require Lecithins value of their own. The with lower HLB values (see to mixing vessels. Phospholipids they contain, explanation on page 8) to such as phosphatidylcholine Emulsifiers retard wetting rates; fatty Extrusion Aids (PC), phosphatidylserine Emulsions are produced Extrusion technology uses powders require higher HLB (PS) and derivatives such by dispersing normally Lecithin as a processing aid values.
