Abstract
In this study, the chemical composition and microbiological properties of Orgu cheese produced from raw milk and sold in the Şanlıurfa market were investigated and evaluated in terms of food safety. For this purpose, Orgu cheese samples were collected from 18 different retail points and analyzed. According to the results, the mean chemical composition of the Orgu cheeses was determined as follows: pH 5.10±0.061, titratable acidity 0.35±0.051% (as lactic acid), dry matter 44.99±2.411%, fat 13.81±4.582%, fat in dry matter 30.37±9.210%, protein 22.33±2.794%, water-soluble nitrogen 0.14±0.078%, ripening index 4.04±1.891%, salt 7.23±1.124%, salt in dry matter 16.13±2.771%, and ash (including salt) 8.70±0.23%. The total aerobic mesophilic bacteria, total lactic acid bacteria, coliform bacteria, and yeast-mold counts of the cheeses were determined as 6.65±0.571 log cfu g⁻¹, 6.01±0.617 log cfu g⁻¹, 1.49±1.200 log cfu g⁻¹, and 3.89±0.442 log cfu g⁻¹, respectively.
Özet
Bu çalışmada Şanlıurfa piyasasında satılan çiğ süt kökenli Örgü peynirlerin kimyasal ve mikrobiyolojik parametreleri incelenmiş ve gıda güvenliği açısından değerlendirilmiştir. Bu amaçla 18 farklı satış noktasından örnek alınmış ve analize tabi tutulmuştur. Analiz sonuçlarına göre Örgü peynirlerin kimyasal bileşimi pH 5.10±0.061, titrasyon asitliği %0.35±0.051 (L. A.), kurumadde %44.99±2.411, yağ %13.81±4.582, kurumaddede yağ %30.37±9.210, protein %22.33±2.794, suda çözünen azot %0.14±0.078, olgunlaşma indeksi %4.04±1.891, tuz %7.23±1.124, kurumaddede tuz %16.13±2.771 ve kül (tuz dahil) %8.70±0.23 olarak belirlenmiştir. Peynirlerdeki toplam aerob mezofilik bakteri sayısı 6.65±0.571 log kob-1, toplam laktik asit bakteri sayısı 6.01±0.617 log kob-1, koliform bakteri sayısı 1.49±1.200 log kob-1 ve maya-küf sayısı da 3.89±0.442 log kob-1 olarak belirlenmiştir.
