“…Adsorbent and ion exchange materials are categorized not only on the basis of their matrix composition, polarity, and chemical and physical resistance but also by their particle size distribution, their inner and specific surface areas, density, and porosity as well as their pore radius distribution (10).…”

A comprehensive overview of adsorption and ion exchange technology applied for food and nutraceutical production purposes is given in the present paper. Emanating from these fields of application, the main adsorbent and ion-exchange resin materials, their historical development, industrial production, and the main parameters characterizing these sorbents are covered. Furthermore, adsorption and ion exchange processes are detailed, also providing profound insights into kinetics, thermodynamics, and equilibrium model assumptions. In addition, the most important industrial adsorber and ion exchange processes making use of vessels and columns are summarized. Finally, an extensive overview of selected industrial applications of these technologies is provided, which is divided into general applications, food production applications, and the recovery of valuable bio- and technofunctional compounds from the byproducts of plant food processing, which may be used as natural food additives or for their potential health-beneficial effects in functional or enriched foods and nutraceuticals.

Adsorption / Sorption / Multilayer / Kinetics / Fast MeasurementJäntti introduced a method to calculate the adsorption equilibrium by measuring the actual adsorbed amount three times after a change to the gas pressure. He successfully applied the method to gas/solid systems in which simple adsorption processes occur. In the present paper we discuss a more general approach for different modes of measurement (adsorption and desorption), including sorption processes obeying second order differential equations.

“…Because small effects are to be measured with high sensitivity, the instruments, measuring procedure and evaluation methods are standardised [4][5]. Two journals are devoted especially to thermal analysis: Thermochimica Acta (Reed Elsevier, Amsterdam) and Journal of Thermal Analysis and Calorimetry (Springer Science + Business Media, Heidelberg and Akadémiai Kiadó, Budapest).…”
