The natural zeolites (NZs) are low-cost natural materials, available in large quantities in different parts of the world, with good mechanical and thermal properties, ion exchange capacity, ability to adjust pH, high surface area and adsorption capacity. Despite their wide range of applications, the use of NZs is limited in industrial processes (where synthetic zeolites are preferred) due to presence of impurities in their structure and the properties which could not be optimized by nature. These limitations can b...

The use of synthetic or natural zeolites in food processing and medical (drug or drug support systems, nutritive supplements) applications also depends on their behavior under digestive conditions. This study aims to investigate the changes in the crystalline structure of natural zeolites in simulated in vitro digestion conditions and the interaction with simulated body fluid (SBF, pH=7.40) and simulated gastric fluid (SGF, pH=1.20). The different pH of used simulated biological fluids may result in interactions b...
