Thaumatin is widely used as a natural sweetener and flavor enhancer in the food and beverage industry. Due to its intense sweetness, it is often incorporated into products like chewing gum, desserts, and beverages to reduce the need for sugar. It is particularly valued in low-calorie and sugar-free products, as it provides sweetness without contributing to calorie content. Additionally, thaumatin is used in pharmaceuticals to mask the bitter taste of certain medications, improving patient compliance. Its natural origin also makes it a preferred choice in organic and natural food products. Beyond its sweetening properties, thaumatin is sometimes utilized in cosmetics and personal care items for its mild flavor and stabilizing effects.
