Food-grade, Gel, Acrylic, Weak Base Anion Exchange Resin
AmberLite FPA55 Ion Exchange Resin is an acrylic, gel, weakly basic, anion exchange resin for use in the nutrition and bioprocessing industries.
Compared to the AmberLite FPA53 Ion Exchange Resin, AmberLite FPA55 has been designed to have a short rinse. This improved
rinse profile gives some cost benefits in process operations and provides a choice between AmberLite FPA55 and the more classic AmberLite FPA53, depending on the particular needs.
The extremely flexible acrylic polymer matrix provides outstanding physical stability and greater resistance to organic fouling than conventional polystyrene-based resins, leading to longer life in the application.
Nutrition Applications
AmberLite FPA55 Ion Exchange Resin has been particularly useful in dairy applications where the combination of stability and an improved rinse profile has been noted. It can also be used for deashing and deacidification of food streams, including starch-based sweeteners, and for the treatment of organic acids.
The gel structure of AmberLite FPA55 gives it higher capacity and longer run lengths than macroporous resins. AmberLite FPA55 has higher basicity than other weakly basic ion exchange resins, making it an excellent choice for the removal of weak organic acids.
Bioprocessing Applications
AmberLite FPA55 Ion Exchange Resin is an excellent resin for removing organic color bodies in many bioprocessing applications such as natural product extraction and recovery of antibiotics from fermentation broth.
