Kurutulmuş Meyve Örneklerinde Mikrobiyolojik Kalite Özelliklerinin Araştırılması

Bu çalışmada kurutulmuş kayısı, incir, siyah üzüm, sarı üzüm, elma, erik ve dut örneklerinde mikrobiyolojik kalitenin araştırılması amaçlanmıştır. Kurutulmuş meyve örnekleri toplam mezofilik aerob bakteri, koliform, Escherichia coli, Staphylococcus aureus, Staphylococcus-Micrococcus spp., küf-maya ve sülfit indirgeyen anaerob bakteri varlığı yönünden standart analiz yöntemleri ile incelenmiştir. E. coli (%10) ve sülfit indirgeyen anaerob bakteriler (%10) sadece kurutulmuş siyah üzüm örneklerinde; S. aureus ise sadece kurutulmuş erik (%20) ve kurutulmuş dut (%10) örneklerinde saptanmıştır. Analiz edilen kurutulmuş meyve örneklerinin tamamı küf ve maya sayısı açısından Türk Gıda Kodeksi’ne göre kabul edilebilir sınırlar içerisindedir. Bu çalışma ile analiz edilen kurutulmuş meyve örneklerinin mevcut durumda halk sağlığı açısından risk oluşturmadığı saptanmıştır. Ancak analiz edilen örneklerde patojen bakteri ve hijyen indikatörü mikroorganizmaların bulunması kötü muhafaza koşullarında halk sağlığı açısından sorunlara neden olabileceğini düşündürmektedir.

Research of Microbiological Quality Properties in Dried Fruit Samples

In this research the aim was to determine microbiological quality in dried apricot, fig, black grape, white grape, apple, plum, and mulberry samples. Dried fruit samples were examined by standard analysis methods in terms of total mesophilic aerob bacteria, coliform, Escherichia coli, Staphylococcus aureus, Staphylococcus-Micrococcus spp., mould-yeast and sulphide reducing anaerobic bacteria. E. coli (10%) and sulphide reducing anaerobic bacteria (10%) were only detected in dried black grape samples. S. aureus was only detected in dried plum (20%) and dried mulberry (10%) samples. All of the analyzed dried fruit samples were within the acceptable limits according to Turkish Food Codex in terms of yeast and mold. By this study it was determined that analyzed dried fruit samples do not threat public health. However, presence of pathogen and hygiene indicator microorganisms in the analyzed samples makes us think that bad preservation conditions may cause problems in terms of public health.
