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

Abstract

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.
