Stevioside Extraction And Purification

Separation Technique Based on Ion Exchange & Adsorption

Stevioside is mainly extracted from the roots and leaves of stevia leaves, with the highest content of stevioside in leaves. Its sweet taste mainly consists of stevioside A, B, C, D, E. Stevioside can be extracted with water, and after clarification and crystallization, extracts of different purities can be obtained.

Stevioside is 250-450 times sweeter than sucrose, but because of the presence of stevioside A, it has a distinct bitter taste and astringency.
Our technology in stevioside extraction is based on the principle of ion exchange and adsorption, using a series supporting separation system to achieve extraction, decolorization, demineralization, purification and other important steps. Our technology has achieved great success in China.

Sunresin has conducted in-depth research in the field of stevia refining. Sunresin once hosted the China Stevia Industry Technical Exchange Conference and achieved great success. China's stevia manufacturers like to work with Sunresin and continue to accelerate their industry upgrades through Sunresin's technology.

Advancing Ergothioneine Biosynthesis through Adsorption and Separation Technology

Sunresin has developed Uniform Particle Ion Exchange Resin using targeted research and development, advanced chromatographic equipment, and strict quality control, utilizing new synthetic biology technology. This resin is designed to address the impurities and high salt content of existing fermentation processes used to produce ergothioneine. It is used for chromatographic desalination, decolorization, and purification, achieving an inorganic/organic salt removal rate of over 95% in high salt systems, reducing conductivity to below 50μs/cm. Moreover, the uniform particle characteristic of the resin allows for lower pressure drop in the resin bed, larger online liquid processing capacity, lower resin breakage rate, and better impurity and salt removal compared to conventional resins. This results in higher yields and significantly improved production efficiency, while reducing production costs.
