Steviol Glycoside

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.

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:
5–10% stevioside (250–300X of sugar)
2–4% rebaudioside A — most sweet (350–450X of sugar) and least bitter
1–2% rebaudioside C
½–1% dulcoside A.

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.

Stevia side effects

Stevia got side effects ? We will see the latest study on stevia.

* Is stevia Toxic? – No. Stevia has been used in Japan since 1970 and there have been no reports of toxicity or other side effects.

* Is stevia Mutagenic? – No. The Japanese Food and Drug Safety Center has found stevia not to be mutagenic. Only one study has shown stevia to be potentially a mutagenic and this study has been criticized for errors in procedure. Scientist in Great Britain said that according to the study’s formula, distilled water is mutagenic.

* Is it a contraceptive? Two studies showed stevia to have a contraceptive effect. The first study was done in Uruguay over 30 years ago and since then no one has been able to reproduce the results. The second study was done by a graduate student in Rio de Janeiro and the results and methods have been questionable. Multiple other studies have shown that stevia has no contraceptive effect.

* Is Stevia Safe? Absolutely. Stevia has been used around the world with NO reports of stevia overdose or toxicity to humans in the past forty years.

There you have it. This latest study indicate stevia is safe for consumption. Especially for diabetic patient. Choose a sugar free life.
