Abstract
Bu çalışmada Bursa'da tüketilen 43 adet peynir örneği incelendi. Fosfat buffer solüsyonunda (pH 7.3, 0.067 M) soğuk zenginleştirmeye alınan örneklerden 4°C'de 21 gün inkübasyondan sonra Cefsulodin irgasan novobiocin (CIN) agar yüzey ekim metodu ile ekim yapıldı. Hiçbir numuneden Yersinia enterocolitica izole edilemedi. Numunelerde ortalama tuz oranı % 6.55, rutubet oranı% 52 ve pH 5.16 olarak belirlendi. Sonuç olarak, Bursa'da tüketilen peynirlerin hijyenik kalitesinin oldukça yetersiz olduğu saptandı.
In this study, 43 cheese samples has been examined which consumed in Bursa. The samples were inoculated into the surface of Cefsulodin irgasan novobiocin (CIN) agar after three-ıveeks cold enrichment 4°C in phosphate buffered saline (PBS,pH= 7.3, 0.067 M) containing 10% peptone. None of the samples was positive for Yersinia enterocolitica. In the chemical analyses of samples, the average values of moisture and salt contents were found to be 52 %, 6.55 % respectiveJy. The average value of pH was found to be 5.16. Asa result, the hygienic quality of cheese which were consumed in Bursa were determined to be unacceptable.
