Abstract

In this study, it is aimed to determine the most suitable drying condition in terms of drying time, color and vitamin C criteria by drying the fruit of ‘Gerçekcioğlu’ rosehip variety. The fruits were dried in microwave dryer 360, 540, 720 and 900 W power values. ​​The fruits were dried drying air temperatures of 50, 60 and 70 °C in drying oven. The average drying times determined in the applied microwave power values ​​are as follows 27, 14, 11 and 9 minutes. The average drying times determined in the applied drying air temperatures are as follows 16.5 7.5 and 7 hours. The most suitable drying condition in terms of color value according to freshness was determined at 720 W power in microwave dryer and 60 °C drying air temperature in drying oven. According to fresh rosehip fruits, the most lost vitamin C value was 91.36% at 60 °C in convective dryer and 540 W power in microwave dryer. According to vitamin C value of fresh rosehip fruit, the most appropriate microwave drying condition was 900 W and hot air drying condition was 70 °C.

Özet

Bu çalışmada, ‘Gerçekcioğlu’ kuşburnu çeşidinin meyvesi kurutularak kuruma süresi, renk ve C vitamin kriterleri açısından en uygun kurutma şartının belirlenmesi amaçlanmıştır. Materyal mikrodalga kurutucuda; 360, 540, 720 ve 900 W güç değerlerinde ve etüv kurutucuda ise; 50, 60 ve 70 °C kurutma havası sıcaklıkların da kurutulmuştur. Uygulanan mikrodalga güç değerlerinde belirlenen ortalama kuruma süreleri sırasıyla; 27, 14, 11 ve 9 dakika olarak tespit edilirken, etüv de ise sırasıyla; 16.5 7.5ve 7 saat olarak belirlenmiştir. Tazeye göre renk değeri açısından en uygun kurutma şartı mikrodalga kurutucuda 720 W güç değerinde, etüv kurutucuda ise 60 °C kurutma havası sıcaklığında yapılan kurutma işlemlerinde belirlenmiştir. Taze kuşburnu meyvesine göre, en fazla kaybolan % C vitamini değeri % 91.36 oranla etüv kurutucuda 60 °C sıcaklığında ve mikrodalga kurutucuda ise 540 W güç değerinde hesaplanmıştır. Taze kuşburnu meyvesinin C vitamin değerine göre, en uygun mikrodalga kurutma şartının 900 W, sıcak havalı kurutma şartının ise 70 °C olduğu belirlenmiştir.
