Abstract

The aim of this research was to apply pectin based edible coating for fresh-cut Deveci pears, and toinvestigate their quality changes during cold storage. For this aim, the coated (EC) and uncoated controlsamples (C) were stored at refrigerated (+ 4 °C) temperatures for 10 days. Samples were analyzed fortheir texture, color, weight loss, microbiological load and sensorial characteristics. Results showed thatlightness values (L*) reduced during storage period of 10 days where the most browning occurred inthe control (uncoated) group. Hardness values increased during storage for all samples. The weight lossof samples reached to 1.79 and 2.01 % at the end of 10 days for the coated and uncoated samples,respectively. The microbiological analyses indicated that microbial counts did not considerable increaseduring storage period. Also they were in acceptable level for all samples. Sensory analysis revealed thatcoated samples were considered as more attractive due to their shiny surface and took higher scores (> 4). However, overall acceptability scores considerable reduced especially after 7 days for all samples.Thus, pectin based edible coatings can be successfully applied for fresh-cut Deveci pears to prolongshelf life especially within 7 days of storage

Özet

Bu çalışmanın amacı, pectin bazlı yenilebilir film kaplamasının taze kesilmiş Deveci armutlarına uygulanması ve soğukta muhafaza sırasında meydana gelen kalite değişimlerinin incelenmesidir. Bu amaçla kaplanmış (EC) ve kaplanmamış kontrol örnekleri 10 gün boyunca soğukta muhafaza (+ 4 °C ) edilmişlerdir. Örnekler tekstür, renk, ağırlık kaybı, mikrobiyolojik yük ve duyusal karakteristikleri açısından analizlenmişlerdir. Elde edilen sonuçlar, L* değerinin 10 günlük depolama süreci boyunca düştüğünü ve en fazla kararmanın kaplanmamış (kontrol) örneklerinde olduğu göstermiştir. Sertlik değerleri ise tüm örekler için depolama süreci boyunca artmıştır. 10 gün sonunda ağırlık kayıpları kaplanmış ve kaplanmamış örnekler için sırasıyla % 1.79 ve % 2.01 düzeyine ulaşmıştır. Mikrobiyolojik analizler ise, mikrobiyal sayının tüm analizlenen örnekler için kabul edilebilir ve uygun düzeyde olduğunu göstermiştir. Bu sayım ayrıca tüm numuneler için depolama boyunca hafifçe artmıştır. Duyusal analizler, kaplanmış örneklerin daha parlak dış yüzeye sahip olmalarından dolayı fazla beğenildiklerini ve daha yüksek puanlar (> 4) aldıklarını ortaya koymuştur. Bunula birlikte, genel beğeni skorları tüm örnekler için özellikle 7 gün sonrasında düşmüştür. Dolayısıyla pektin bazlı yenebilir filmler, taze kesilmiş Deveci armutlarının raf ömürlerinin uzatılması amacıyla 7 günlük depolama süreçlerinde başarıyla uygulanabilmektedir.
