Chemical Properties:White to light yellow crystalline powder. Melting point 198 ℃. 1g the materials can be dissolved in 800ml water, slightly soluble in ethanol. This optical rotation [α] 20/D is-39.3 ° (C = 5.7, H2O). It quickly drains wet in the air. High temperature, acidic and alkaline solution is relatively stable.

4. Application:

The product has a refreshing sweet taste, sweetness is about 200-300 times that of sucrose. Slightly bitter taste at high concentrations, sweet taste in the mouth is not easy to disappear. The product is one of the natural sweeteners closest to sucrose. As low alorie food sweetener, it can low pressure. As a sucrose substitute agent, the maximum amount should not exceed 1/3, in case of after taste. According to GB2760-86 regulations,it can be used for liquid and solid drinks, candy and pastries according to normal production needs. The disadvantage of this product is its high molecular weight and  poor permeability.

5.Storage:

Stevia endures heat and light, is very stable in a pH range of 3 to 10,and easy to store.
