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, lecithin acts as a dough conditioner, enhancing the elasticity and shelf life of baked goods. It is also utilized in the production of dietary supplements and pharmaceuticals due to its ability to improve the absorption of active ingredients. Additionally, lecithin is applied in cosmetics and personal care products, where it functions as a moisturizer and stabilizer in creams and lotions. Its versatility makes it a valuable ingredient across various industries.
