Difference Between Stevia and Reb-A
San Antonio TX. Stevia, the green leafy plant original of South America, used by the Guarani people as sweetener and medicine, can be up to 350 times sweeter than cane sugar, so nowadays the highly purified stevia extract is used as zero – calorie, natural origin sweetener in many countries. It is important to say that the whole stevia leafor the crude stevia extracts are not approved for use by the leading food and beverage authorities in most countries.
The sweetening components of stevia are called steviol glycosides. According to the Global Stevia Institute (GSI), the highly purified stevia extract can contain just one steviol glycoside or several. The GSI says that one of the best-tasting and sweetest of all the steviol glycosides is high purity Rebaudioside-A (Reb-A), which can be 200 to 300 times sweeter than sugar. Reb A is also one of the most abundant steviol glycosides found in the stevia leaf. Reb A can be extracted from the stevia leaf and can be used in products to achieve a very similar taste of sucrose. The purification process of stevia, according to the GSI, includes the following steps: The dried leaves are steeped in water in order to release their sweet tasting steviol glycoside compounds –among them Reb A. Next, the liquid is filtered and separated from the plant material. Then the extract is purified and dried to obtain high purity stevia leaf extract with the same Reb A as found in stevia’s natural leaves.
After several scientific studies, Reb-A’s used as zero calorie sweetener in foods and beverages has been approved by leading authorities.
Several research studies on stevia have shown there is no accumulation of Reb-A and other steviol glycosides in the body during metabolism. Stevia extract or Reb A has zero calories essentially due to this poor absorption in the digestive tract.
It is the highly purified stevia extract – containing Reb A or other steviol glycosides – what food and beverage manufacturers use as an ingredient in their products.
