Saponins are widely used in the food and beverage industry as natural emulsifiers and foaming agents. They help stabilize mixtures of oil and water in products like salad dressings, sauces, and carbonated drinks. In the pharmaceutical sector, saponins are valued for their immune-boosting and anti-inflammatory properties, often incorporated into vaccines and dietary supplements. They also play a role in cosmetics, where they act as natural cleansers and foaming agents in shampoos, soaps, and skincare products. Additionally, saponins are utilized in agriculture as biopesticides and growth promoters, enhancing plant resistance to pests and diseases while improving soil health. Their ability to interact with cholesterol makes them useful in research for studying cell membrane properties and drug delivery systems.
