Migration test
Since most manufacturers recommended sterilisation
of the baby bottle prior to use (specified on the leaflet),
the bottles were sterilised. The common treatment was
selected as boiling in water for 5 min. The bottles were
then subjected to the conventional migration test for
hot fill conditions, i.e. 2 h at 70C. The simulant used
for milk was 50% ethanol as specified in European
Union legislation (2007/19/EC; European Commission
2007). This was identified as the worst-case simulant
for this study since for juices, which would be modelled
by acetic acid 3%, the age group of the infant would be
older than the most sensitive population of newborn
where the simulant for milk would apply. The simulant
was pre-heated to 70C, and a volume corresponding
to the specified volume of the baby bottles was added
to the item. The test specimens were covered with a
glass plate weighted to ensure the absence of evaporation
and placed in a convection oven for 2 h at 70C.
The loss of simulant was measured in preliminary tests
and was shown not to exceed 3%. Calibration curves
were done in the 50% ethanol simulant in order to take
recoveries into account. After treatment the migration
solution was transferred from the baby bottle into a
glass bottle with a PTFE-lined cap and left to cool
prior to analysis. An aliquot was then used in a glass
GC vial with a PTFE-lined cap for analysis.

Second and third migration tests were performed
according to the repeated-use conditions for foodcontact
material (82/711/EEC as amended; European
Economic Community 1982). The bottles were quickly
rinsed with deionised water between two migration
tests. In a first phase only the first migration was
analysed to assess the nature and amount of migrants.
In cases where substances from the first migration
exceeded limits specified in the legislation, third
migration solutions were also analysed to assess the
final compliance of the articles. Blank samples were
also prepared from a portion of the simulant used for
the migration tests.

Frågan är ju hur relevanta dessa tester är för verklig användning. Säg att man bara hettar upp mjölken till 37 grader och kontakten med silikonet varar i 5 minuter.
Jag köpte för övrigt denna till min dotter tidigare idag men vete fan om det var så klokt:

Hon kanske får lära sig att dricka ur glas eller kopp som vanligt folk istället...
