Abstract

Okratoksin A (OTA) Aspergillus ve Penicillium türleri tarafından sentezlenen nefrotoksik etkili bir toksindir. OTA ayrıca insanlarda immunotoksik, teratojenik ve karsinojenik etkileri nedeniyle kansere neden maddeler arasında yer almaktadır. Tahıl, kahve çekirdeği, fındık, kakao, bakliyat, bira, şarap, baharat ve kuru üzümde bulunabilen bir mikotoksindir. OTA kısmen kararlı bir moleküldür ve gıdalara uygulanan işlemlerden sonra bile değişmeden kalabilir. Bu nedenle hayvansal gıdalarda OTA varlığına yönelik çalışmalar yapılması önerilmektedir.

Presence of Ochratoxin A in Various Foods

Abstract

Ochratoxin A (OTA) is a mycotoxin which contaminates different plant products, including cereals, coffee beans, nuts, cocoa, pulses, beer, wine, spices and raisin. OTA is synthesized by Aspergillus and Penicillium species. OTA has been reported to have nephrotoxic, immunotoxic, teratogenic and carcinogenic effects in humans. OTA is a partly stable molecule and it may remain unchanged in food even after processing. Therefore, it is suggested that OTA content should be monitored in animal origin foods.
