Saponins are widely used in the food industry as natural emulsifiers and foaming agents, enhancing the texture and stability of products like beverages and desserts. In cosmetics, they serve as cleansing agents in shampoos and soaps due to their ability to create a rich lather and remove dirt effectively. In agriculture, saponins are utilized as biopesticides to protect crops from pests and fungi, offering an eco-friendly alternative to synthetic chemicals. Additionally, they are studied in the pharmaceutical field for their potential health benefits, including cholesterol-lowering and immune-boosting properties. Their ability to form complexes with cholesterol also makes them useful in research and diagnostic applications.
