Atımlı ışık uygulamasının badem yüzeyindeki Salmonella Enteritidis PT 30 inaktivasyonuna etkileri farklı voltaj, numune ile lamba mesafesi ve işlem süresi bakımından değerlendirilmiştir. Bademlerin yüzeyine 20 µL Salmonella Enteritidis PT 30 kültürü ekimi yapılıp, sonra 24 saat oda sıcaklığında kurumaya bırakılmıştır. Ekim yapılmış bademlere, üç değişik voltajda (3000, 3400 ve 3800V); iki farklı numune ile lamba mesafesinde (14.1 ve 19.1 cm) 20 ya da 60 s süresince atımlı ışık uygulanmıştır. Badem yüzeyindeki Salmonella populasyonu 0.44 ile 4.14 log CFU/badem oranında azalmıştır. Proses faktörlerinden 3800 V, 14.1 cm ve 60 s ile atımlı ışık uygulaması Salmonella miktarını TSAYE’de 4.14 log, XLD agarda ise 4.09 log CFU/badem azaltmıştır. Atımlı ışık yöntemi, uygulanan proses faktörlerine bağlı olarak, badem yüzeyindeki sıcaklığı 25’den 35-50ºC’ye kadar yükseltmiştir. Bu çalışmaya göre atımlı ışık teknolojisi badem gibi nem oranı düşük olan gıdaların Salmonella mikrobiyal inaktivasyonda uygulanabileceği belirlenmiştir.

The effect of pulsed light treatment on the inactivation of Salmonella Enteritidis PT 30 on almonds was determined based on voltage, distance between sample and lamp and treatment time. Almonds were spot-inoculated with 20 µL of Salmonella Enteritidis PT 30 culture and then dried for 24 h at an ambient temperature. Almonds were treated with pulsed light at 3000, 3400 and 3800V at distances of 14.1 or 19.1 cm for 20 or 60 s. Pulsed light treatments reduced Salmonella populations by 0.44 to 4.14 log CFU/almond. Almonds treated with 3800V at 14.1 cm distance for 60 s resulted in a reduction by 4.14 log CFU/almond in Salmonella counts on TSAYE and 4.09 log CFU/almond on XLD agar. After pulsed light exposure, almond surface temperature increased from 25 to 35-50ºC depending on treatment conditions. Results indicated that pulsed light had a potential to be used in the microbial inactivation of Salmonella in almonds and other low moisture foods.
