Özet
Araştırma, %0.5 ve %1.0 eugenol uygulamalarının 103 kob/g, 104 kob/g, 105 kob/g L. monocytogenes 4b ile inokulasyon sonrası etkisi ve aynı oranlardaki eugenol uygulamalarının toplam genel canlı mikroorganizmalar üzerine etkisini belirlemek amacıyla yapıldı. Deneysel numunelerde başlangıç (0. gün), 4C'de muhafazanın 5. ve 10. günlerinde, -18C'de donmuş muhafazanın 30. ve 60 günlerinde L.monocytogenes, toplam canlı mikroorganizması sayısı ve pH değerleri belirlendi. Deneysel İnegöl köftelerin başlangıçta (0.gün) ve donmuş muhafazanın 30. gününde toplam mezofilik aerob mikroorganizma sayısında istatistiki bakımdan gruplar arası önemli farklılıklar gözlemlenmiştir (P0.01). Muhafaza periyodu dikkate alındığında ise deneysel uygulamalar yapılan numunelerin başlangıçta belirlenen toplam canlı mikroorganizma sayısının muhafaza periyodu süresince azaldığı gözlemlenmiştir (P 0.01). Genel olarak değerlendirildiğinde eugenol uygulanmayan numunelerin başlangıçta tespit edilen L. monocytogenes sayısının 60. gün donmuş muhafaza sonrasında %0.5 ve %1 eugenol uygulanan numunelerde belirlenen L. monocytogenes sayısından daha yüksek olduğu belirlenmiştir. Bu farklılık muhtemelen eugenolün L. monocytogenes üzerine inhibe edici etkisinin olabileceğini göstermektedir
In this research, it was aimed to determine the effect of eugenol with concentrations of 0.5% and 1.0% on L. monocytogenes with amount of 103 cfu/g, 104 cfu/g, 105 cfu/g and on total aerobic mesophilic microorganisms. In the experimental samples, presence of L. monocytogenes, the total aerobic mesophilic microorganisms and pH values were determined in the beginning (day 0), 5th and 10th days of cold storage at 4°C and 30th and 60th days of frozen storage at -18°C. There were significant differences in the number of total aerobic mesophilic microorganisms at the beginning day (day 0) and 30th day of the experimental İnegöl meatballs between groups, statistically (P<0.01). Considering the storage period, it was observed that the number of initial total aerobic mesophilic microorganisms was reduced in experimental samples during whole storage time (P<0.01). As an overall evaluation it was determined that the initial number of L. monocytogenes untreated with eugenol was higher than the samples treated with eugenol 0.5% and 1% after 60 days of frozen storage. This difference probably indicates that eugenol has an inhibitory effect on L. monocytogenes.
