Saponins are widely used in the food and beverage industry as natural foaming agents and emulsifiers. They are commonly added to beverages like beer and soft drinks to enhance foam stability. In the pharmaceutical sector, saponins are utilized for their immune-boosting and anti-inflammatory properties, often incorporated into vaccines and herbal medicines. They also play a role in cosmetics, where they act as natural surfactants in skincare products, helping to cleanse and moisturize the skin. Additionally, saponins are employed in agriculture as bio-pesticides and growth stimulants for plants, improving crop yield and resistance to pests. Their ability to form complexes with cholesterol makes them useful in cholesterol-lowering dietary supplements as well.
