Lecithin is widely used as an emulsifier in the food industry, helping to blend ingredients like oil and water that would otherwise separate. It is commonly found in products such as chocolate, margarine, and salad dressings to improve texture and stability. In baking, it enhances dough elasticity and extends shelf life.

In the pharmaceutical and cosmetic industries, lecithin acts as a surfactant and moisturizer, improving the absorption of active ingredients in creams, lotions, and medications. It is also used in dietary supplements for its potential benefits in supporting brain health and reducing cholesterol levels.

Additionally, lecithin serves as a release agent in industrial applications, preventing materials from sticking to molds during manufacturing processes. Its versatility and natural origin make it a valuable ingredient across various sectors.
