Similar to NH2, PSA has weak anion exchange and positive phase retention. The two amino groups (pKa = 10.1 and 10.9) of PSA provide greater ion exchange capacity and can extract polar compounds through hydrogen bonds. In addition, PSA can form complex with metal ions and retain some metal ions.
Technology Advantage
Larger switching capacity than NH2;
Effectively remove a variety of interfering ingredients in food.
Application
Remove the fatty acids (such as oleic acid, palmitic acid, linoleic acid), organic acids, some pigments, metal ions, carbohydrate interferents and so on in the food matrix
