Infants’ hedonic responsiveness to food odours: a longitudinal study during and after weaning (8, 12 and 22 months)

Table 1 Kendall correlations (unilateral tests) between mouthing scores at two ages

Hedonic value	Odorants	8 to 12 months		12 to 22 months

The odorants were peach/apricot (PEA), apple (APP), vanillin (VAN), strawberry (STR), trimethylamine (TRI), 2-isobutyl-3-methoxypyrazine (PYR), dimethyl disulphide (DIM), butyric acid (BUT). The number of participants varied between 140 and 175 because in some cases, toddlers did not complete the session, thus data for some odorants were missing. ^*Significant correlation (P <0.05).
