During the processing from the corn raw materials to the final allulose product, Sunresin provides a complete purification process including: ion exchange deashing, activated carbon decolorization, chromatographic separation, etc., to achieve high-quality crystalline allulose. Currently, the two core process units in allulose production are the differential isomerization of fructose and the purification process.

On March 7, Forbes China released the list of "2023 China’s 100 Power Businesswomen". Dr. Gao Yuejing, chairwoman of Sunresin, was selected on the list, demonstrating the outstanding contributions of the "she power" in the development of Sunresin.

Sunresin provides a mature ion exchange resin process for acetic acid purification, which can remove bromine or chloride ions in acetic acid to less than 5ppm, or undetectable levels. The fixed bed mode is recommended for the ion exchange process for acetic acid purification, which runs continuously and removes impurities through the front and back resin columns to improve the removal accuracy and ensure the maximum utilization of the resins.
