Lecithin is widely used as an emulsifier in the food industry, helping to blend ingredients that typically do not mix well, such as oil and water. It is commonly found in products like chocolate, margarine, and salad dressings to improve texture and consistency. In baking, it enhances dough elasticity and shelf life. Beyond food, lecithin is utilized in the pharmaceutical and cosmetic industries as a stabilizer and moisturizer in creams, lotions, and medications. It also serves as a dietary supplement, supporting brain health and liver function due to its high phosphatidylcholine content. Additionally, lecithin is used in industrial applications, such as a release agent in manufacturing processes.
