Stevioside is the main strong sweet component contained in Stevia rebaudiana, also known as stevioside. It is a diterpene glycosome and belongs to tetracyclic diterpenes, which is at position C-4 α- A glucose is connected to the carboxyl group and a disaccharide is connected to the C-13 position. Stevioside is white or yellowish loose powder or crystal under normal conditions. It is stable at room temperature. Its sweetness is about 300 times that of sucrose. Its taste is similar to sucrose. It has pure sweetness and no odor. The residual taste lasts longer than sucrose, and the heat is only one third of sucrose. It is non alcoholysis, good thermal stability, low toxicity and wide application range. It is called the third natural sugar source after sucrose and beet sugar.

 Function 

Stevioside has the effects of anti hypertension, reducing blood glucose and inhibiting cancer cells.

 Application 

1. As sweetener, pharmaceutical excipient and flavoring agent

In Brazil and Paraguay, stevia has been used as a sweet drink by local residents since the 16th century. Stevioside is not only used in the food industry, but also used in the pharmaceutical industry as flavoring agent (correcting the different and strange taste of some drugs) and excipients (tablets, pills, capsules, etc.).

2. For the treatment of patients with hypertension

The drug prepared with Stevia as the main component is used in the treatment of patients with hypertension. All antihypertensive and sedative drugs are stopped during the treatment. As a result, the total effective rate of antihypertensive is almost 100%. Among them, 85% were markedly effective. The common symptoms of patients with hypertension, such as dizziness, tinnitus, dry mouth and insomnia, were improved.

3. for the treatment of diabetic patients

In 70s, Japan reported treating Stevia with Stevia. It is common knowledge as everyone knows that the water extract from dried leaves of Stevia in Paraguay has the effect of treating diabetes.

 Physicochemical properties 

Stevioside is white or yellowish loose powder or crystal under normal conditions, stable under normal temperature, and the heat is only one third of sucrose.

1. Sweetness and flavor properties

The sweetness of stevioside is about 300 times that of sucrose. The taste is similar to that of sucrose. It has pure sweetness and no odor, but the residual taste lasts longer than that of sucrose. Like other sweeteners, stevioside decreases with the increase of concentration, and has a slight bitter taste. Stevioside in cold drinks is sweeter than stevioside in hot drinks.

2. Heat resistance

Stevioside has good heat resistance, and its sweetness remains unchanged when heated below 95 ℃ for 2 hours; When the pH value is 2.5 ~ 3.5 and the concentration of stevioside is 0.05%, the residual rate of stevioside is about 90% when heated at 80 ° ~ 100 ℃ for 1 hour; When the pH value is between 3.0 ~ 4.0 and its concentration is 0.013%, the residual rate is about 90% when it is stored at room temperature for six months. When the 0.1% stevioside solution in glass container is exposed to sunlight for seven months, the residual rate is more than 90%.

3. Solubility of stevioside

Stevioside is soluble in water and ethanol, but insoluble in organic solvents such as benzene and ether. The higher the refining degree, the slower the dissolution rate in water. The solubility in water at room temperature is about 0.12%. Due to the adulteration of other sugars, sugar alcohols and other sweeteners, the solubility of commercial products is very different and easy to absorb moisture.

4. Bacteriostasis

Stevioside is not assimilated and fermented by microorganisms, so it has antibacterial effect, which makes it widely used in pharmaceutical industry.
