The sweet ingredients of the Stevia Plant

Ingredients of Stevia

The particular sweetness of the leaf is mainly due to the so-called rebaudioside A. However, the leaf of the Stevia plant also contains ingredients that can cause a bitter aftertaste in the taste cells.

The leaves of the stevia plant contain more than 100 secondary plant substances (phytochemicals), mainly from the group of terpenes and flavonoids. 8 of these secondary plant substances (phytochemicals), which are called glycosides, are responsible for the sweetening properties of the stevia leaves.

These secondary carbon compounds are also found in numerous other life forms. Other special components of Stevia rebaudiana Bertoni are rebaudioside C, D and E, stevioside and the so-called dulcoside A.

The proportions of the respective ingredients depend on the growth conditions and above all on the location of the plant. In general, however, it can be said that the steviosides are the largest component of the leaves with a total weight share of between 6-18%. Rebaudioside A takes second place with about 2-4%, followed by Rebaudioside C with about 1-2%.

Does Stevia contain calories?

Even though glycosides are so-called carbon compounds in which sugar molecules are linked to alcohol, 100mg of steviol glycosides contain only about 0.5 calories. To achieve a comparable sweetness, you would need about 30g of sugar (125 kcal). The reason for this small amount of calories is that the sugar contained in the steviol glycosides is not broken down by the digestive tract, but is removed directly.

Although carbohydrates are also absorbed when consuming Stevia, the energy balance remains unaffected. This is due to the indigestible molecular structure of the carbohydrates.

Industrially manufactured Stevia products may contain energy carriers or fillers. In most cases, however, the amounts are very small so that even diabetics can neglect them in terms of calories.
