Abstract:Plant proteins often carry off-notes, necessitating customized aroma addition. In vitro studies revealed protein−aroma binding, limiting release during consumption. This study employs in vivo nose space proton transfer reaction-time-of-flight−mass spectrometry and dynamic sensory evaluation (time intensity) to explore in-mouth interactions. In a lupin protein-based aqueous system, a sensory evaluation of a trained "green" attribute was conducted simultaneously with aroma release of hexanal, nonanal, and 2-nona… Show more
