Title : Preservation and quality enhancement of fresh dates using innovative edible gum Arabic coating
Abstract:
Due to the high perishability and limited shelf life of fresh fruits, there are challenges in their storage and distribution. Consequently, there is an increasing demand for new preservation approaches to maintain the quality of fresh fruit, such as date palm fruit at the Khalal stage, while prolonging their shelf life. Using an innovative edible coating derived from Gum Arabic displays the potential to conserve and enhance the quality of fresh dates. This method has successfully reduced decay after harvesting, preserved optimal soluble solids content, and prevented the decline of titratable acidity in fruits. The study examines the viability of employing a Gum Arabic coating to extend the freshness and quality of dates. Gum Arabic, sourced from the Acacia tree, is acknowledged for its capacity to create a protective layer that guards against moisture loss and microbial spoilage. The coating application covers the date surface with a Gum Arabic solution, forming a transparent and adaptable barrier. To evaluate the efficacy of the Gum Arabic coating in maintaining date quality, a series of experiments were carried out in controlled storage conditions. Fresh date palm fruits, harvested at the peak of the Khala stage, were divided into two sets: one set was coated with Gum Arabic, while the other was left uncoated as the control. Both sets were then stored under normal conditions, with periodic assessments of various quality parameters. The most critical factor affecting the shelf life of fresh date palm fruits is the loss of fruit moisture during storage, which can lead to shrinkage and changes in texture and fruit shelf life. Results demonstrate that the Gum Arabic coating effectively reduces moisture loss from the dates, preserving their fullness and firm texture during storage. This is attributed to the barrier characteristics of the Gum Arabic film, which inhibits water evaporation from the fruit surface. Moreover, the findings indicate that the Gum Arabic coating significantly extends the shelf life of fresh dates by safeguarding fruit quality parameters and maintaining their sensory and nutritional attributes over a 62-day storage period using a 10% Gum Arabic concentration. Evaluations of the coated date fruits' sensory aspects revealed no substantial variances (p > 0.05) in overall acceptability compared to the control group. The Gum Arabic coating does not introduce unwanted tastes or smells to the dates, thus preserving their inherent sensory qualities. This is crucial for ensuring customer satisfaction and improving the market competitiveness of the coated dates. The research offers valuable insights into sustainable preservation methods for fresh dates and progressing postharvest practices in the date palm sector. Further improvements in coating compositions and application techniques can enhance the scalability and efficiency of this innovative preservation method, supporting the continuous growth and sustainability of the date palm industry.
