Sensory and molecular characterisation of human milk odour profiles after maternal fish oil supplementation during pregnancy and breastfeeding

► Focused chemo-analytical and sensory characterisation of fish aroma marker substances. ► Selective and sensitive odourant quantification by stable isotope dilution assays. ► Molecular characterisation of fish oil aroma influence on human milk aroma profiles. ► Analytical and statistical evaluation of a potential odourant transmission into milk. ► Discussion of chemical and physiological aspects related to odour transfer.
