Abstract

In this research, it was aimed to
determine chemical, biochemical, textural, microbiological properties and some
volatile compounds of traditional Mengen cheese. As results of chemical and
biochemical analyses in Mengen cheese samples, dry matter was average
51.4±5.34%, ash 3.57±0.73%, protein 24±3.29%, fat 19.05±4.99%, salt 2.19±0.85%,
pH 5.72±0.44, acidity 0.36±0.21%, ripening index % 2.94±1.25, lipolysis value
(ADV) 0.87±0.73 meqKOH/100g-fat were found. Microbiologic
analyses showed that Mengen cheese samples had average TMAB count as 8.15±1.14
log CFU/g, LAB 7.19±1.42 log CFU/g, yeast-mould 4.97±1.15 log CFU/g, coliform
6.09±1.36 log CFU/g, E. coli 3.79±1.87 log CFU/g, S. aureus
3.96±1.6 log CFU/g were found, Listeria, Salmonella, coagulase positive S.
aureus, E. coli 0157 pathogen bacteria were not detected. It was
determined that the textural properties were found in a wide range and 130
volatile compounds were obtained in the samples.

Bu araştırmada, geleneksel peynirlerimizden biri olan
Mengen peynirinin kimyasal, biyokimyasal, tekstürel ve mikrobiyolojik
özelliklerinin tanımlanması ve bazı uçucu bileşenlerinin belirlenmesi
amaçlanmıştır. Kimyasal ve biyokimyasal analizlerde elde edilen ortalama
sonuçlarda kuru madde %51.4±5.34, kül %3.57±0.73, protein %24±3.29, yağ
%19.05±4.99, tuz %2.19±0.85, pH 5.72±0.44, asitlik %0.36±0.21, olgunlaşma
indeksi değeri % 2.94±1.25, lipoliz değeri 0.87±0.73 meqKOH/100g-yağ olarak
bulunmuştur. Mengen peyniri örneklerinde yapılan mikrobiyolojik analizlerin
ortalama sonuçları toplam mezofilik aerobik bakteri 8.15±1.14 log KOB/g, laktik
asit bakteri 7.19±1.42 log KOB/g, maya-küf 4.97±1.15 log KOB/g, koliform
6.09±1.36 log KOB/g, E. coli 3.79±1.87 log KOB/g, S. aureus 3.96±1.6
log KOB/g değerlerinde bulunmuş, Listeria, Salmonella, koagülaz pozitif
S. aureus, E. coli O157 patojenlerine rastlanmamıştır. Tekstürel
özelliklerin geniş bir profile sahip olduğu ve 130 uçucu bileşen bulunduğu
tespit edilmiştir.
