I had to laugh at this study!! The manufacturers of artificial infant milk 
are trying everything to simulate human milk....

Vegetable acceptance by infants: Effects of formula flavors

Abstract
Individual differences in acceptance patterns are evident as early as the 
child's first experiences with a particular food. To test hypothesis that 
the flavor of formula fed to infants modifies their acceptance of some 
foods, we conducted a within- and between-subjects design study in which 
two groups of 6- to 11-month-old infants were tested on two separate days. 
One group was currently feeding a milk-based formula whereas the other was 
feeding a protein hydrolysate formula, a particularly unpleasant tasting 
formula to adults that contains similar flavor notes (e.g., sulfur 
volatiles) with Brasscia vegetables such as broccoli. In counterbalanced 
order, acceptance of pureed broccoli/cauliflower was determined during one 
test session and pureed carrots on the other. Although there were no group 
differences in the amount of carrots consumed, hydrolysate infants 
consumed significantly less broccoli/cauliflower relative to carrots when 
compared to those who were currently fed milk based formulas (F(1,72 df)
=4.43; p=0.04). The mothers of hydrolysate infants were significantly more 
likely to report that their infants did not enjoy feeding the 
broccoli/cauliflower (54.2%) when compared to mothers of infants being fed 
milk-based formulas (28.0%; Chi-Square (1 df)=4.79; p=0.03). Such findings 
are consistent with prior research that demonstrated a sensory specific 
satiety following repeated exposure to a particular flavor in milk. We 
hypothesize that when infants are experiencing a flavor in milk or 
formula, in the short term, the preference that develops is specific to 
the context it is experienced in (e.g., milk). Over the longer term, the 
preference may generalize to other contexts such as solid foods. 
Hydrolysate infants were also significantly more likely to be judged by 
their mothers as being more active (F(1,69 df)=3.95; p=0.05) and hesitant 
(F(1,69 df)=6.55; p=0.01) when compared to those infants who were feeding 
milk-based formulas, a finding that further supports the hypothesis that 
mother–child dynamics surrounding early feeding impacts upon mothers' 
perception of their children's temperament.
