Abstract

Arugula (Eruca sp.) has been incorporated into Uruguayan production systems in the last two decades, particularly in organic production, but it has a short shelf life (4 days) due to inadequate postharvest management. Therefore, the aim of this study was to validate refrigerated storage for local arugula leaves production and marketable conditions in order to increase their postharvest life. The main problems in the quality of the leaves were characterized and quantified based on their overall appearance, weight loss (WL), total soluble solids (TSS), total phenolic content (TP), total antioxidant capacity (TAC), color, chlorophylls and total carotenoids, under refrigerated storage (RS) (4 °C and 95% RH) and after 3 or 4 days at room temperature (RT) (20 °C and 75% RH). For each refrigerated storage time (0, 3, 6, 9, 12, 16, 20, 24, 27 days) and room temperature time (0+3; 3+3; 6+3; 9+3; 12+4; 16+4; 20+4; 24+3 days), defect-free leaves were stored in three polypropylene bags (50 ± 5 g of arugula leaves). The results showed that by applying adequate refrigerated treatment, it would be possible to increase the shelf life of arugula leaves in current production systems by 2.25 times, with minimal reduction in their bioactive compounds.
