Türkiye’de satışa sunulan çaylarda ve bitki çaylarında fitalat ester düzeylerinin belirlenmesi

Fitalatlar, gıda ürünlerinde ve kişisel bakım ürünlerinde plastikleştiriciler ve katkı maddeleri olarak kullanılır. Yapılan araştırmalar, fitalatların insan sağlığı üzerinde olumsuz etkilere sahip olduğunu göstermiştir. Beş fitalat esteri (dibütil fitalat (DBP), benzil bütil fitalat (BBP), di(2-etilheksil) fitalat (DEHP), diisononil fitalat (DINP) ve diizodesil fitalat (DIDP)) 30 farklı çay ve bitkisel çaylarda likit kromatografi kütle spektrofotometresi (LC/MS/MS) ile incelenmiştir. Bu çalışma, Türkiye'de tüketilen siyah çay, yeşil çay ve bitkisel çaylarda fitalatların varlığını göstermiştir. Analiz edilen çay örneklerinde en yaygın DBP, 30 örneğin 19’unda (5.78-44.99 µg/kg) tespit edilmiştir. DEHP ikinci en yaygın belirlenen fitalat olup 30 örneğin 14’ünde (5.65-60.83 µg/kg) tespit edilmiştir. Diğer belirlenen fitalat BBP olup, 30 örnekten 5’inde 9.35-44.95 µg/kg olarak tespit edilmiştir.

Determination of phthalate ester levels in teas and herbal teas available in Türkiye

Phthalates are used as plasticizers and additives in food products and personal care items. The conducted studies have demonstrated the negative effects of phthalates on human health. Five phthalates esters (dibutyl phthalate (DBP), benzyl butylphthalate (BBP), di(2-ethylhexyl)phthalate (DEHP), diisononyl phthalate (DINP), and diisodecyl phthalate (DIDP)) were investigated in 30 different types of tea and herbal infusions using liquid chromatography-mass spectrometry (LC/MS/MS). This study demonstrated the presence of phthalates in black tea, green tea, and herbal infusions consumed in Turkey. Among the analyzed tea samples, DBP was the most common, detected in 19 out of 30 samples (ranging from 5.78 to 44.99 µg/kg). DEHP was the second most frequently detected phthalate, found in 14 out of 30 samples (ranging from 5.65 to 60.83 µg/kg). The other detected phthalate was BBP, which was found in 5 out of 30 samples (ranging from 9.35 to 44.95 µg/kg).
