- Abstract
This study aimed to evaluate the synergistic effect of preharvest spraying with alginate and in combination with salicylic acid (SA) and oxalic acid (OA), on the quality parameters and storage life of ‘Red Globe’ grape variety at 0-1°C with 85-90% relative humidity for 60 days. Data of physical and chemical quality parameters were collected at 15-day intervals. The results have shown that alginate coatings delayed changes in weight loss, firmness and berry color compared to control. Alginate coating enriched with oxalic acid and salicylic acid proved to be the most effective applications in restricting stem browning and decay incidence in grapes. Moreover, these formulations contributed to the high antioxidant potential of coated grapes by enriching the phenolic compound content. These findings reveal that preharvest spraying of clusters with alginate combined with SA and OA applications may have high potential for improving storage quality of commercial grapes.
