Examination of changes in certain vitamins in baby foods by capillary electrophoresis

Bu çalışma, bebek mamalarının paketin açıldığı birinci ve onbeşinci günlerdeki d-pantotenat ve niasinin değişiminin yeni bir kapiler elektroforetik yöntemle zamana bağımlı olarak değişimini tanıtmaktadır. Sekiz numunede D-pantotenat miktarı Türk Standartlarının belirlediği değerlerden yüksek bulunmuş, dokuz numunede bulunmamıştır. Yedi numunede niasine rastlanmamıştır. On beşinci günde tüm numunelerde vitamin kayıbı gözlenmiştir.

Bebek mamalarında bazı vitamin değişimlerinin kapiler elektroforez ile incelenmesi (İngilizce)

This study describes the analysis of baby foods regarding time-dependent changes of d-pantothenate and niacin by a new capillary electrophoretic method at first and fifteenth days of opening the packages. D-pantothenate amounts in eight of the samples were found to be higher than those identified in the Turkish Standard and it was not detected in the nine samples. Niacin was not detected in the seven samples. Losses of mentioned vitamins were observed at the fifteenth-day for all samples
