ÖZET
Erzincan'ın Taze Tulum, Erzurum'un Taze Beyaz, Civil ve Kaşar
peynirierinden toplam 51 adet örnek üzerinde aflatoksin analizleri yapılmıştır. Ayrıca,
hu peynir çeşitlerinde aflatohin oluşum potarı.siyelleri araştmlmışıır.Bu amaçla,
peynir örnekleri Aspergillus flavus ve A. parasiricus sporlarıyla aşılanarak5 OC'de
10,21 gün ve 14 hafta, 25 DC'de 10 ve 21 gün depolanmışlar ve bu sürelerin sonurıda
afla/oksin analizlerine tabi tutulmuşlardır.
ince tabaka kromatografisi yöntemiyle yapılan analizlerde, 51 peynir
örneğinin hiç birisinde izlenebilir miktarlarda aflatoksin Mı' Bı, 8 2, Gı ve G2 tesbit
edi!ememiştir.
Bulgular, a:jlatoksijenik suşlarla kontamine olan ve 5 DC'de depolanan taze
peynirierde aflatoksin teşekkülünün olmayacağını, 25 DC'de ise, peynir çeşidine, kü[
suşuna ve inkübasyon süresine bağlı olarak değişeceğini göstermiştir. Soıwçlar,
özellikle Tulum peynirierinin, buzdolabı sıcaklığında mulıajaza edilmesi gereğini
ortaya koymuştur.
AN INVESTIGATION ON AFLATOXIN CONTENT AND
AFLATOXIN FORMATION OF SOME FRESH CHEESE TYPES
SUMMARY
In this research. a:jlatoxin analyses were made in sanıples
from Tulum cheese of Erzincan and White, Civi/ and Kashar cheeses of Erzurum. In
addition to aflatoxin formation potantials on these cheese types were investigated. ALL
of the total 51 cheese samples were obtained freshly. For af/atoxin formation
analysis, cheeses were inocu1ated with Aspergillus flavus or A. parasilicus spores,and stored at 5 OC for 10 and 21 days and 14 weeks. Then, the cheese samples were
examinedfor their aflatoxin contents.
Thin layer chromatography analysis showed that, no detectable levels of
aflatoxin Ml, Bl,B2, Gl, G2 werefowıd in these 51 cheese samples.
The results showed that no ciflatoxinformation was observed in the fresh
cheeses which were contaminated with aflaoxigenic strains and stored at 5 'C. Variable
amounts ofaflatoxin were formed at 25 OC depending on the cheese rype, mold strain
and incubation period. Theesefiru1ings also suggest that the TUıum cheeses should be
accept with refrigeration.
