DuPont™ AmberLite™ FPA53 Ion Exchange Resins
Food Processing Grade, Gel, Acrylic, Weak Base Anion Resin
Description DuPont™ AmberLite™ FPA53 Ion Exchange Resin is an acrylic, gel, weakly basic,
anion exchange resin for use in the nutrition and bioprocessing industries.
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™ FPA53 Ion Exchange Resin is used for deashing and deacidification of
food streams, including starch-based sweeteners. Other uses include the treatment of
organic acids and dairy products.
The gel structure of AmberLite™ FPA53 gives it higher capacity and longer run lengths
than macroporous resins. AmberLite™ FPA53 contains tertiary amine functionality, but
it has higher basicity than other weakly basic ion exchange resins, making it an
excellent choice for the removal of weak organic acids. In addition, this resin contains
no strongly basic functional sites, allowing the deacidification of glucose and fructose
syrups with no product degradation, as well as no isomerization.
Bioprocessing Applications
AmberLite™ FPA53 Ion Exchange Resin is a unique solution for the decolorization of
organic color bodies of most bioprocessing applications. It is extensively used in the
recoveries of β-lactam antibiotics from fermentation broth. AmberLite™ FPA53 is
widely used in conjunction with AmberLite™ XAD1600N Polymeric Adsorbent in the
biopurification of cephalosporin C.
