Abstract

<p>Porous pectin particles were developed as a protein adsorbent using a template-assisted spray drying method with calcium carbonate (CaCO3) as a template for pore formation. The specific surface area was controlled from 177.0 m2/g to 222.3 m2/g by adjusting the CaCO3 concentration. All porous pectin particles showed rapid adsorption (~65% within 5 min) and high adsorption capacity, increasing from 1543 mg/g to 2621 mg/g. The high percentage of available binding sites located in the macropores resulted in a high performance of this material, making it a promising advanced adsorbent for various macromolecules in the food and pharmaceutical industries. The porous pectin particles are derived from a natural polymer, contributing to sustainable development.</p>
