Abstract: The adjustment and control of specific product characteristics, e.g., foaming behavior of carbonated beverages, requires an understanding of influencing factors along with reliable analytical methods. However, due to the overlay of different phenomena, i.e., release of CO2 and action of surface-active molecules contained in such beverages, it is difficult to assess their respective contribution to foam appearance and stability. This study aimed at evaluating a new methodological approach to investigate the interfacial and foaming properties of carbonated beverages. Using beer as an example, it was attempted to establish a correlation between interfacial properties and foaming behavior. To ensure a comprehensive dataset, surface tension, interfacial dilatational rheology, and foaming properties including foam structural characteristics of six different German beers of three different types (i.e., Pils, wheat beer and Koelsch), which are known to exhibit distinct foaming behavior, were measured. While foams prepared with CO2 as sparging gas did not show any differences in foam aging, use of air for foaming enabled differentiation based on beer type. Differences observed in foam structural characteristics and stability could not be related to dynamic surface tension but might be linked to interfacial dilatational properties. Overall, the presented multiscale approach can be seen as promising concept for further experimental studies on carbonated beverages. [ABSTRACT FROM AUTHOR]
