Over the last decade there has been a growing interest in low-calorie alternatives to carbohydrate-based sweeteners. Recent publications have shown a dramatic increase in attention toward natural extracts such as the Stevia rebaudiana plant, not only for its sweetening effect but also for additional health benefits attributed to the plant. The major sweetening components are stevioside, rebaudioside A, rebaudioside C, and dulcoside A, each of which is over 300 times sweeter than sucrose based sweeteners. Because of this they are widely used in beverages and foodstuffs.
