DA302 De-colorization Resin
DA302 De-colorization Resin

Macroporous Strong Base Anion Exchange Resin

(Model DA302, Equivalent Rohm&Haas FPA90Cl Food Grade,Lewatit S6368)

 

DA302 is a sort of strong base anion exchange resin which has quaternary ammonium group in the styrene framework with macroporous structure. The special macroporous structure of this resin makes the resin has stable physical characteristic, and it is suitable for the decolorizing of sugar solution (especially for cane sugar). 

The resin D302 will not release any harmful matter in using and will not change the taste and quality of the beverage and will not do harm to the food. The exchange capacity can easily resume while regenerated by neutralize or alkalize sodium chloride solution after deprive large molecular water affinities anion organic matter and pigment in sugar solution.
