Rubusoside is primarily used as a natural sweetener due to its high sweetness intensity, which is significantly greater than that of sucrose. It is often employed in the food and beverage industry to reduce calorie content while maintaining a desirable sweet taste. Additionally, it is utilized in dietary supplements and health products aimed at weight management and blood sugar control, as it has minimal impact on glucose levels. Rubusoside is also explored in pharmaceutical formulations for its potential antioxidant and anti-inflammatory properties, making it a versatile ingredient in both functional foods and medicinal applications.
