Abstract

Ochratoxin A (OTA) is a mycotoxin which is synthesized by some Aspergillus and Penicillium species and may exists in especially cultivated cereals, coffee beans or coffee granules, wine and various spices. OTA exhibits Carcinogenic, mutagenic and teratogenic affects for humans and animals. In this conducted study, OTA contents of 30 different coffee samples that were provided from the local markets were determined by using high performance liquid chromatography. The experiments were carried out using the fluorescence detector and applying the 330 nm extinction and 450 nm emission wavelengths. The column temperature and pressure were set to 25°C and 83 barr, respectively. The flow rate was chosen as 0.9 mL/min. Coffee samples were dissolved in ethanol. Analyses were performed by using the C18 (200 mm 4.6 mm I.D., 5 µm particle size). It was observed that OTA standards and samples have a signal at approximately 11.287 min. Deionized (water: acetonitirile: acetic acid) (49.5:49.5:1), (v:v:v) mixture was used as the mobile phase. The obtained results showed that different amounts of OTA for all 30 samples were determined and 12 of them have lower OTA content according to the limits of Turkish Food Codex.

Özet

Okratoksin A (OTA), bazı Aspergillus ve Penicillium türleri tarafından sentezlenen özellikle işlenmiş tahıllar, kahve çekirdekleri veya granül kahveler, şarap ve çeşitli baharatlarda bulunabilen bir mikotoksindir. OTA insan ve hayvanlarda kanserojen, mutajenik ve teratojenik etkiler göstermektedir. Gerçekleştirilen bu çalışmada yerel marketlerden temin edilen 30 adet kahve örneği içerisindeki OTA miktarı Yüksek Basınçlı Sıvı Kromatografisi (YPSK) cihazı ile tayin edilmiştir. Çalışmalar floresans dedektör kullanılarak Ex 330 Em 450 nm dalga boylarında gerçekleştirilmiş, kolon sıcaklığı 25°C, sistem basıncı 83 bar olarak ölçülmüştür. Akış hızı 0.9 ml/dk olarak seçilmiştir. Kahveleri çözmek için etanol kullanılmıştır. Analiz boyunca C18 (200 mm 4.6 mm I.D., 5 µm partikül boyutuna sahip kolon kullanılmıştır. OTA standardı ve numunelerin yaklaşık 11.287 dk da sinyal verdiği görülmektedir. Mobil faz olarak (su:asetonitril:asetik asit) (49.5:49.5:1) (h:h:h) kullanılmıştır. Çalışılan 30 adet örneğin tümünde çeşitli miktarlarda OTA varlığı tespit edilmiş olup bunlardan sadece 12 tanesinin Türk Gıda Kodeksi tarafından belirlenen limitler altında olduğu tespit edilmiştir.
