Hören, sehen, riechen, schmecken, fühlen – mit unseren Sinnen nehmen wir Informationen über unsere Umwelt auf. So können wir die Qualität von Lebensmitteln einschätzen, aber auch – teils ohne es zu merken – mit unseren Mitmenschen kommunizieren. Gerade die Forschung zur chemischen Kommunikation beim Menschen erlebt nach Jahrzehnten einen erneuten Aufschwung in der Aroma‐ und Geruchsforschung, einem Teilbereich der Lebensmittelchemie.

Body odors change during development, and this change influences the interpersonal communication between parents and their children. The molecular basis for this chemical communication has not been elucidated yet. Here, we show by combining instrumental and sensory analyses that the qualitative odorant composition of body odor samples is similar in infants (0-3 years) and post-pubertal children (14-18 years). The post-pubertal samples are characterized by higher odor dilution factors for carboxylic acids and by the presence of 5α-androst-16-en-3-one and 5α-androst-16-en-3α-ol. In addition to the olfaction-guided approach, the compounds 6-methylhept-5-en-2-one (6MHO), geranyl acetone (GA) and squalene (SQ) were quantified. Both age groups have similar concentrations of 6MHO and GA, whereas post-pubertal children tend to have higher concentration of SQ. In conclusion, sexual maturation coincides with changes to body odor chemical composition. Whether those changes explain differences in parental olfactory perception needs to be determined in future studies with model odors.
