Abstract

In this paper, the effect of heat treatment on rutin and total phenolic compounds in black mulberry juice with the heating periods (0, 5, 10, 15, 20 and 30 min) at temperatures ranging from 70 to 95 °C is analyzed and experimental results are presented. Firstly, fresh black mulberry fruits were processed to black mulberry juice and then thermal treatment is performed. Liquid chromatographic and spectrophotometric methods were used for the analysis of rutin and total phenolic compounds, respectively. During thermal processing, degradation of rutin and total phenolic compounds in black mulberry juice were fitted to a first-order reaction kinetic model. Arrhenius relationship was used for the description of temperature dependence of reaction. Activation energies for rutin and total phenolic compounds between 70 to 95 °C were found as 50.53 and 34.89 kJ mol-1, respectively.

Özet

Bu çalışmada, karadut suyunun 70-95 °C sıcaklık aralığında ve farklı ısıtma periyotlarında (0, 5, 10, 15, 20 ve 30 dk.) ısıl işleme tabi tutulmasıyla karadut suyunun rutin ve toplam fenolik içeriğinde meydana gelen değişimler belirlenmiştir. Bu amaçla taze karadut meyveleri öncelikle meyve suyunu işlenmiş ardından ısıl işlem uygulaması yapılmıştır. Karadut suyunda rutin tayini sıvı kromatografik, toplam fenolik tayini ise spektrofotometrik yöntemle belirlenmiştir. Isıl işlem sırasında, karadut suyunda ısıl işlem uygulamasına bağlı olarak rutin ve toplam fenolik içeriğindeki bozunmalar birinci dereceden kinetik modele uymuştur. Rutin ve toplam fenolik reaksiyonların sıcaklık bağımlılığı Arrhenius ilişkisi ile tanımlanmıştır. Rutin ve toplam fenolik içeriğinin 70-95 °C sıcaklık aralığındaki aktivasyon enerjileri sırasıyla 50.53 ve 34.89 kJ mol-1 bulunmuştur.
