Abstract

In this study, some physical, chemical and microbiological properties of Çalma pekmez n=45 produced in Tokat and its vicinity were determined. The ranges for pH, water activity, soluble solids brix , Hunter L, a and b values were 4.65.77, 0.550-0.710, 63-93%, 31.38-54.2, 8.08-19.31, and 23.59-42.01, respectively. The logarithmic counts of total aerobic mesophilic bacteria, total coliforms, fecal coliforms and osmophilic yeasts were in the ranges of

Tokat Yöresinde Üretilen Çalma Pekmezin Bazı Fiziksel, Kimyasal ve Mikrobiyolojik Özellikleri

Abstract

Bu araştırmada Tokat yöresinde üretilen Çalma pekmezin n=45 bazı fiziksel, kimyasal ve mikrobiyolojik özellikleri belirlenmiştir. Test edilen örneklerin pH değerlerinin 4,60-5,77, aw değerlerinin 0,550-0,710, briks değerlerinin ise 63,0-93,0 arasında değişim gösterdiği belirlenmiştir. Örneklerin Hunter L parlaklık değerleri 31,38-52,0, a kırmızılık değerleri 8,08-19,31, b sarılık değerlerinin ise 23,59-42,01 arasında değiştiği bulunmuştur. Mikrobiyolojik analizler sonucunda, toplam aerobik mezofilik bakteri sayısı
