Voeding beïnvloedt de smaak van moedermelk*
Ui teen Deense studie blijkt dat smaakstoffen in de voeding van de moeder doorgegeven worden in de moedermelk. Iedere stof doet dat in zijn eigen tempo en hoeveelheid. Zo is een banaan een uur na het eten door de moeder al niet meer vast te stellen in de moedermelk terwijl de ingrediënten van karwijzaad en zoethout pas na 2 uur volop aanwezig zijn. Acht uur na consumptie was geen enkele smaakstof meer vast te stellen in de moedermelk.
Diet Influences The Taste Of Breast Milk
Researchers from the University of Copenhagen, Denmark, have found that what a mother eats has a fairly instant effect on the taste of her breast milk, as well as influencing what her child preferred to eat.
An infant's first flavour experiences may be through the transfer of dietary flavour compounds into breast milk, say researchers.
Helene Hausner and team asked 18 lactating mothers to consume capsules with various flavourings, such as caraway seed, liquorice, menthol, and banana (100 mg d-carvone, l-menthol, 3-methylbutyl acetate and trans-anethole). The mothers provided samples of breast milk before taking the capsules and several times after. The milk was collected 2, 4, 6, and 8 hours after each capsule was consumed and analysed by a dynamic headspace method and gas chromatography-mass spectroscopy. The quantities of compounds were adjusted according to milk fat content variations.
They found that flavours get into the milk and stay there at different rates and speeds. The Caraway and liquorice compounds reached their peaks in the breast milk two hours after consumption, while the banana compound became undetectable after one hour. All flavours were gone from the breast milk within eight
hours.
The findings in this study might help mothers understand why their child does not want to feed. Hausner says it is possible that breastfed babies may be more receptive to flavours than bottle-fed babies.
