The largest sweetener producers are located in Japan, China, South America and the USA. In the past, organic solvents were often used to extract and process the steviosides.
Today, new methods are used. Instead of relying on chemical extraction processes, manufacturers of high-quality foods increasingly prefer raw materials from physical extraction processes using CO2 or water extraction.
The advantage of the CO2 extraction process is that it is gentle, antibacterial, high-yielding and does not require heating.
The traditional processing in Latin America was done without distillation or purification plants. Stevia was processed there into extracts, powders, liquid substances or as medicines. In a simple way, the Stevia leaves were dried or powdered.
