Abstract

Dried persimmon is a relatively new product for Turkish consumers. Thus, the quality characteristics and storage conditions of this product have not yet well-defined. In this study, the effect of frozen storage and modified atmosphere packaging (100% N 2 and 30% CO 2 +70% N 2 ) followed by cold storage on microbiological, physicochemical and sensory quality of semi-dried persimmons was investigated. Both modified atmosphere packaging and frozen storage were effective in suppressing the growth of total aerobic mesophilic bacteria, yeast and mold. Increase in L color values, an indicator of sugar migration, was observed in air and modified atmosphere packaged samples. Increases in a and b color values were recorded during frozen storage probably due to ongoing browning reactions. Moisture contents and firmness values merely changed during storage and were not affected by any of the treatments. Sensory analysis results revealed that color, taste and general acceptability scores of modified atmosphere packaged and freeze-stored samples were significantly higher than those of air packaged ones. Therefore, both modified atmosphere packaging and frozen storage can be recommended to maintain the quality characteristics of semi-dried persimmons.

Özet

Kurutulmuş Trabzon hurması, Türk tüketiciler için nispeten yeni bir üründür. Bu nedenle, söz konusu ürünün kalite karakteristikleri ve depolama koşulları henüz net bir şekilde tanımlanmamıştır. Bu çalışmada, donmuş muhafazanın ve modifiye atmosferde (%100 N 2 and %30 CO 2 +%70 N 2 ) paketleme sonrası uygulanan soğukta depolamanın yarı-kurutulmuş Trabzon hurmalarının mikrobiyolojik, fizikokimyasal ve duyusal özelliklerine etkisi incelenmiştir. Hem modifiye atmosferde paketleme hem de donmuş muhafaza toplam aerobik mezofilik bakteri, maya ve küf gelişimini baskılamada etkili bulunmuştur. Normal ve modifiye atmosferde paketlenen örneklerde, şeker göçünün bir göstergesi olarak L renk değerlerinde artış gözlenmiştir. Donmuş muhafaza edilen örneklerde, gerçekleşen esmerleşme reaksiyonları nedeniyle a ve b renk değerlerinde artışlar meydana gelmiştir. Örneklerin nem içerikleri ve sertlik değerleri depolama boyunca istatistiksel açıdan anlamlı düzeyde değişmemiş ve bu değerler gerçekleştirilen uygulamalardan etkilenmemiştir. Duyusal analiz sonuçları göstermiştir ki, modifiye atmosferde paketlenen ve donmuş muhafaza edilen örneklerin renk, tat ve genel kabul edilebilirlik skorları hava atmosferinde paketlenen örneklerinkinden yüksektir. Bu nedenle, gerek modifiye atmosferde paketleme gerekse donmuş muhafaza teknikleri yarı-kurutulmuş Trabzon hurmalarında kalitenin korunması için önerilebilir.
