“…The reduction of glucose and sucrose values in stored broccoli samples can be related to its use by the plant to generate the energy required for its metabolism, making sugars the main substrate in the respiration duration (Loredana et al., 2023 ; Pinela et al., 2016 ). They serve as pioneers for the biosynthesis of polysaccharides, lipids, proteins, and other compounds (Duffus & Duffus, 1984 ; Parker, 2020 ). Previous studies showed glucose to be more abundant than sucrose in broccoli (Hasperué et al., 2014 ).…”

“…Since broccoli is harvested while still in its immature state, it requires a continuous supply of energy to support high respiration rates (King & Morris, 1994 ). Sucrose, being one of the principal compounds involved in metabolic reactions, undergoes a 50% reduction in broccoli samples stored at room temperature within 6 h of harvest (Parker, 2020 ). The postharvest decline in sugar levels is influenced by the rate of respiration, and higher storage temperatures lead to increased respiration rates in broccoli samples (Tian et al., 2016 ; Parker, 2020 ).…”

To extend the postharvest storage life of broccoli samples (Brassica oleracea L. var. italica), an exogenous application of citric acid (CA), salicylic acid (SA), and putrescine (PUT) was tested in multiple combinations (0.5 and 1 mM) at 4 ± 0.5°C and 90 ± 5% relative humidity (RH) for 21 days (d). The weight loss (WL), respiration rate (RR), total soluble solids (TSS), pH, color (L*, a*, b*, chroma, and hue angle), proximate and mineral contents, phenolic and flavonoid contents, and other biochemical properties of the treated and untreated broccoli samples were evaluated throughout the storage duration. The lowest WL was observed when exposed to 0.5 mM of PUT. 1 mM CA and PUT treatments were affected by RR, depending on storage conditions. The lowest TSS content was observed in broccoli samples treated with 0.5 mM CA among all treatments. The chroma value of the samples was preserved by the 0.5 mM SA treatment. The most abundant element in broccoli samples was potassium in the control application, followed by a 1 mM SA treatment. In addition, the protein content was the highest in the 1 mM PUT treatment. The highest vitamin C was determined in the 1 mM CA treatment, and the most abundant vanillic acid was found in broccoli exposed to the 0.5 mM and treatment. Glucose content was determined at the lowest level in the 0.5 mM SA treatment, while higher increases occurred in other treatments. In terms of these findings, 1 mM CA, 1 mM SA, and 1 mM PUT delay WL, RR, and color degradation and prolong the storage life of broccoli samples stored at 4 ± 0.5°C. It was concluded that the biochemical content, fresh weight, and green color of broccoli samples throughout postharvest and storage can be maintained longer by exogenous application of these natural compounds. Therefore, we recommend 1 mM PUT and 1 mM CA treatments to maintain the quality of broccoli by minimizing losses in morphological properties, mineral, and biochemical compositions during postharvest storage.
