Soy lecithin

Lecithin is a waxy, fatty, yellow-brown substance that comes from plant or animal tissues. Eggs were the original source of lecithin, but many foods now incorporate soy lecithin derived from soybeans instead. This relatively inexpensive and easy-to-produce alternative serves a variety of functions in foods. These primarily arise from its ability to stabilize blends of ingredients. Soy lecithin also adds to your daily intake of the essential nutrient choline.
