Within the scope of this work, the current knowledge on emulsifying and foaming active extracts was extended by investigating a promising extract - sugar beet extract - in more detail using taste dilution analysis. It exhibited saponin-containing fractions with slight off-taste as well as high foaming activities. All eleven isolated saponins possess taste recognition thresholds greater than 1.0 mmol/L. In addition, the foam activity of these and also other compounds was measured, providing the most comprehensive overview about the foam activities of individual saponins. In addition to isolation and characterization, an LC-MS/MS method was developed and validated for simultaneous quantitative analysis of all obtained sugar beet saponins in numerous matrices.
