Stevia is commonly used in various products for its intensely sweet taste. Some of the common names for stevia that can be seen on ingredient labels are:

• High-purity stevia
• Stevia

How is stevia made?

Stevia leaves will be processed before it reaches your coffee, tea or desserts. The artificial sweeteners will be completely refined and processed in laboratories.  

Stevia leaves will be harvested, dried and soaked in hot water. The liquid will then be filtered to get the extract from the stevia leaves. The extract that is collected is called steviol glycosides.

The extract will be blended with additives like maltodextrin and dextrose to cut the intense sweetness. So that stevia can be easily incorporated into the desired foods.

Forms of stevia

Stevia is available in different forms depending on the processing method, and the ingredients added.

Some of the stevias that are available in markets are true blends of stevia. These forms are one of the heavily processed stevias. This type of stevia is made with rebaudioside A (Reb A)— a type of refined stevia extract that is added along with other sweeteners like erythritol and maltodextrin.

The processing of stevia involves soaking the leaves in hot and passing them through a filter with alcohol. This will help isolate Reb A, and then the extract is dried, crystallised and combined with sweeteners and fillers.

Green stevia is the least processed, which is made by grinding and drying whole stevia leaves. However, FDA-approved stevia is the stevioside. Green stevia will require additional research on its safe usage.
