Abstract

İlk nem içeriği %95 olan çilek meyvesi nem içeriği % 10’un altına düşene kadar farklı kurutma yöntemleri ile kurutulmuştur. Çilek dilimleri ultrases ön işlemi uygulandıktan sonra mikrodalgada 180W gücünde ve 70°C sıcaklıkta 1,2 m/s hava hızında kurutulmuşlardır. 70°C sıcaklıkta kurutulacak çilek dilimlerinde kontrol grubu ayrıldıktan sonra 40kHz frekansta, 10, 20, 30 dk. ultrasonik su banyosunda hammadde:su oranı 1:4 olduğu ultrases ön işlemi uygulanmıştır. Mikrodalgada kurutulacak meyvelerde de kontrol grubu ayrıldıktan sonra hammadde:su oranı 1:4 olacak şekilde 40 kHz frekansta 30 dakika ultrases ön işlemi uygulanmıştır. Kurutma sırasında düzenli aralıklarla ağırlık ölçümü ve numune alımı yapılmıştır. Çalışma sonucu elde edilen veriler literatürde bulunan 7 farklı ayrılabilir nem içeriği modellerine (Newton, Page, Henderson and Pabis, Logaritmik, Midilli, Çift Terimli, Wang and Singh) göre karşılaştırılmış, değerlerine göre en uygun kuruma modeli Midilli modeli olarak belirlenmiştir. Ancak uygulanan modeller arasında en az parametreyle çileğin nem oranı değerinin süreye göre değişimini en iyi tanımlayan modelin ise Newton modeli olduğu sonucuna varılmıştır.

DRYING OF STRAWBERRIES WITH ULTRASOUND-ASSISTED HOT AIR AND MICROWAVE METHODS AND DETERMINATION OF THE DRYING MODEL

https://izlik.org/JA48DG52SF

Abstract

Strawberry fruit with an initial moisture content of 95% was dried by different drying methods until the moisture content was below 10%. Strawberry slices were dried at 70°C an air velocity of 1.2 m/s and 180W power in the microwave by applying Ultrasound(US) pretreatment. After separating the control group from the fruits to be dried at 70°C, ultrasonic pre-treatment was applied at 40kHz frequency for 10, 20, 30 minutes in an ultrasonic water bath with a raw material:water ratio of 1:4. In the fruits to be dried in microwave, after separating the control group, US pre-treatment was applied at a frequency of 40 kHz for 30 min with a raw material:water ratio of 1:4. During drying, weight measurement and sampling were carried out at certain intervals. The data obtained as a result of the study were compared according to 7 different separable moisture content models in the literature (Newton, Page, Henderson and Pabis, Logarithmic, Midilli, Binomial, Wang and Singh) and the most suitable drying model was found as Midilli model. However, it was concluded that Newton model was the best model that best describes the change of moisture content value of strawberry according to time with the least parameters among the applied models.
