Crawfish chitosan, prepared from crawfish shell chitin, was demonstrated to be an effective ligand‐exchange column material for recovery of amino acids from seafood processing wastewater. In comparison with commercial chitosan, crawfish chitosan, loaded with copper or amino copper, showed higher recovery rates of amino acids. Recovery from amino copper‐crawfish chitosan columns was pH dependent, with reduction at higher pH values. Eluatc was completely free of copper ions when treated with a second crawfish chitosan column. The amino acids recovered by this treatment have potential application as seafood flavors in terms of their sensory attributes.
