Özet:

 In recent years, pomegranate cultivation has significantly increased both in Turkey and worldwide. Consequently, the importance of postharvest preservation has grown in parallel with the rising volume of harvested pomegranates. This study aimed to investigate the effects of chitosan Ch, salicylic acid SA, and their combined application chitosansalicylic acid ChSA on the quality attributes of pomegranate arils during cold storage. Following aril extraction, treatments were applied, and the arils were stored at 4 C and 90 relative humidity for 16 days. At 4 day intervals during the storage period, samples were analyzed for weight loss, aril color hue angle, total soluble solids TSS, titratable acidity TA, total phenolic content TPC, total antioxidant activity TAA, ascorbic acid vitamin C content AsA, and total anthocyanin content TA. Results indicated that both Ch and SA treatments were effective in maintaining the quality attributes of the arils compared to the control, with the combined application ChSA showing enhanced effectiveness. The ChSA treatment was particularly effective in reducing weight loss and slowing changes in hue angle, TSS, and TA. Additionally, it has been determined that postharvest application of chitosansalicylic acid could be an effectice method for keeping quality attributes in pomegranate arils during a cold storage period of 16 days.

 Nar yetiştiriciliği ülkemizde ve dünyada son yıllarda çok hızlı bir şekilde artmaktadır. Hasat edilen nar miktarındaki artışa bağlı olarak muhafazası da aynı oranda önem kazanmıştır. Bu çalışmada danelenmiş narlara kitosan, salisilik asit ve bu uygulamaların birlikte kullanımı olan kitosansalisilik asitin hasat sonrası soğukta muhafaza süresince kalite özellikleri üzerine etkileri araştırılmıştır. Daneleme işlemi yapılan narlar uygulamalar yapıldıktan sonra 4 C ve 90 oransal nem içeren soğuk hava deposunda 16 gün süreyle depolanmıştır. Muhafaza süresince 4 gün arayla danelerde ağırlık kaybı, dane rengi hue açısı, suda çözünebilir toplam kuru madde miktarı SÇKM, titre edilebilir asitlik miktarı TEA, toplam fenolik madde miktarı TFM, toplam antioksidan aktivite miktarı TAA, askorbik asit C vitamini miktarı AsA ve toplam antosiyanin miktarı TA analiz edilmiştir. Araştırma sonucunda kitosan Ch ve salisilik asit SA uygulamasının kontrol ile karşılaştırıldığında danelerde kalite özelliklerini korumada etkili olduğu, bu etkinin birlikte kullanıldığında ChSA daha da arttığı saptanmıştır. ChSA uygulamasının ağırlık kaybının azaltılması, dane rengi, SÇKM, TEA değerlerindeki değişimin yavaşlatılmasında etkili bir uygulama olduğu görülmüştür. Ayrıca TAA, TFM, AsA ve TA kapsamlarında oluşan değişimlerin yavaşlatılmasında etkili olduğu tespit edilmiştir. Sonuç olarak 16 gün muhafaza edilen nar danelerinde hasat sonrası Ch ve SA uygulamalarının birlikte kullanımının kalite özelliklerini korumada etkili olduğu belirlenmiştir.
