Sorbitan Tristearate, also known as Span 65, is an emulsifier widely used in the food industry. It is a yellowish-white, waxy solid that is insoluble in water but soluble in organic solvents. Span 65 is commonly used in bakery products, confectionery, and dairy products to stabilize oil-in-water emulsions and improve texture and consistency. It functions by forming a protective layer around fat droplets, preventing their coalescence and maintaining a uniform texture and stability in food products. Span 65 also contributes to the extended shelf life of various processed foods.
