Steviol Glycoside / Natural sugar

Description:

The steviol glycosides are responsible for the sweet taste of the leaves of the stevia plant (Stevia rebaudiana Bertoni). These compounds range in sweetness from 40 to 300 times sweeter than sucrose. They are heat-stable, pH-stable, and do not ferment.They also do not induce a glycemic response when ingested, making them attractive as natural sweeteners to diabetics and others on carbohydrate-controlled diets.

Advantages:

         * Natural, green sugar
         * Lower calorie
         * High sweetness
         * Good coordination
         * Strong stability
         * Great potential medicinal value

Structure:

The diterpene known as Steviol is the aglycone of stevia's sweet glycosides, which are

constructed by replacing steviol's carboxyl hydrogen atom (at the bottom of the figure)

with glucose to form an ester, and replacing the hydroxyl hydrogen (at the top of the

figure in the infobox) with combinations of glucose and rhamnose. The two primary

compounds, stevioside and rebaudioside A, use only glucose: Stevioside has two

linked glucose molecules at the hydroxyl site, whereas rebaudioside A has three,

with the middle glucose of the triplet connected to the central steviol structure.

In terms of weight fraction, the four major steviol glycosides found in the stevia plant tissue are:

Rebaudioside B, D, and E may also be present in minute quantities; however, it is suspected that rebaudioside B is a byproduct of the isolation technique. The two majority compounds stevioside and rebaudioside, primarily responsible for the sweet taste of stevia leaves, were first isolated by two French chemists in 1931.
