Lecithin is a waxy, fatty, yellow-brown substance that comes from plant or animal tissues. It serves a variety of functions in foods. These primarily arise from its ability to stabilize blends of ingredients. Lecithin also adds to your daily intake of the essential nutrient choline. Lecithins are oily substances that occur naturally in plants (rice, soybeans) and animals (egg yolks). Lecithin is used in food as an emulsifier, instantiser, antioxidant and flavour protector, often providing a finishing touch that brings quality and excellence to many food products.
