Mevcut çalışma, limon meyvelerinin raf ömrünü uzatmak amacıyla orman ürünlerinden elde edilen biyolojik olarak parçalanabilen bir reçine kaplamanın kullanımını incelemektedir. Son araştırmaların sonuçları incelendiğinde; reçine kaplı limonların, kaplanmamış kontrol numunelerine göre önemli ölçüde daha düşük nem kaybı sergilediği ve daha yüksek su aktivitesi seviyelerini koruduğu gösterilmektedir. Bu durum, reçine kaplamanın etkili bir şekilde nem bariyeri görevi görerek dehidrasyonu azalttığını öne sürmektedir. Ayrıca kaplamalı limonlardaki brix seviyelerinin depolama süresi boyunca sabit kaldığı, kontrol grubunda ise kayda değer bir düşüş yaşandığı belirtilmektedir. Ph seviyeleri de reçine kaplamanın limonların asitliğini korumaya yardımcı olduğunu ve bunun da limonların korunması için çok önemli olduğunu göstermektedir. Kaplanmış numunelerde limonların sertliğinin daha iyi korunduğu ve kontrol grubuna göre önemli ölçüde daha düşük ağırlık kaybı sergilediği vurgulanmaktadır. Reçine kaplamanın fizyolojik ve biyokimyasal bozulmayı azaltmadaki etkinliği belirtilmektedir. Duyusal değerlendirmeler; reçine kaplı limonların, kaplanmamış kontrol numunelerine kıyasla üstün görsel çekiciliğe, dokuya ve genel kabul edilebilirliğe sahip olduğunu ortaya koymaktadır. Artırılmış raf ömrü ve kalitesi nedeniyle reçine kaplı limonlara yönelik potansiyel tüketici tercihleri öne çıkmaktadır. Genel olarak reçine kaplamanın uygulanmasının, farklı depolama koşullarında kalite özelliklerini koruyarak limonların raf ömrünü önemli ölçüde uzattığı gösterilmektedir. Bu çalışma; narenciye meyvelerinin korunması, hasat sonrası kayıpların azaltılması ve pazarlanabilirliğin artırılması için biyolojik olarak parçalanabilen reçine kaplamaların etkili bir yöntem olarak kullanılma potansiyelini göstermektedir.

Possibilities to Extend the Shelf Life of Citrus Fruits with Natural Rosin Coating, Benefiting from Forest By-Products Review

Öz

The current study examines using a biodegradable rosin coating derived from forest products to extend the shelf life of lemon fruits. Recent research findings show that rosin-coated lemons exhibit significantly lower moisture loss and maintain higher water activity levels compared to uncoated control samples. This suggests that the rosin coating effectively acts as a moisture barrier, reducing dehydration. Additionally, the Brix levels in coated lemons remain stable throughout the storage period, while the control group experiences a notable decline. The pH levels also indicate that the rosin coating helps preserve the acidity of lemons, which is crucial for their preservation. The coated samples retain firmness better and exhibit significantly lower weight loss compared to the control group. The effectiveness of the rosin coating in reducing physiological and biochemical degradation is highlighted. Sensory evaluations reveal that rosin-coated lemons possess superior visual appeal, texture, and overall acceptability compared to uncoated control samples. Due to the extended shelf life and improved quality, potential consumer preferences for rosin-coated lemons are indicated. Overall, the application of rosin coatings significantly extends the shelf life of lemons by preserving quality attributes under various storage conditions. This study demonstrates the potential of biodegradable rosin coatings as an effective method for preserving citrus fruits, reducing postharvest losses, and enhancing marketability.
