“…Condensation inside the trays was also observed in this treatment. These results disagree with those of Lemoine et al, (2009), who found lower water losses in heat treated florets.…”

“…Chlorophylls decreased during storage with a decrement of 39 % for chlorophyll a and 44 % for chlorophyll b after 21 days at 5 ºC. Similarly, Lemoine et al, (2009) also found chlorophylls decreases in freshcut broccoli florets. At the end of the storage, PMA+H treatment had a higher concentration of chlorophylls pigments than PMA.…”

“…On the other hand, PMA+H samples presented a 30 % decrease after 21 days of storage at 5 ºC, and always exhibited differences with PMA. Lemoine et al, (2009) found an important decrease in phenolic in heat treated samples after 7 days of storage, and then levels slightly increased. They explained that behavior as a consequence of a decrease in the activity of phenylalanine ammonia lyase enzyme (PAL) that has been related to phenolic compounds synthesis.…”

“…Considering the above-mentioned factors, it is necessary to offer to the consumers a convenience product, and to evaluate different postharvest procedures aiming to preserve the quality of fresh-cut broccoli florets (Zhuang et al, 1995;Lemoine et al, 2008Lemoine et al, , 2009). …”

The shelf life of horticultural commodities depends on pre‐ and postharvest factors, such as soil fertilization and postharvest handling. The current study aimed to evaluate fresh‐cut celery's postharvest quality as affected by the rate and type (organic and chemical) of nitrogen (N) fertilizer and postharvest treatments. Celery (‘Tall Utah’) crop was grown in a field in Karaj, Iran. The experimental design was a randomized complete block with three replications and seven preharvest (fertilizer), and five postharvest treatments. Organic fertilizers were vermicompost (VER) and bio‐organic fertilizer [farmyard and livestock manure plus Trichoderma harzianum (COM)]. Chemical fertilizers were urea (46% N) at high rate [322 kg·ha1 N (UREA_HIGH)], optimal rate [196 kg·ha−1 N (UREA_OPT)], and low rate [138 kg·ha−1 N (UREA_LOW)]; ammonium nitrate [35% N (AN)] at 196 kg·ha−1 N; and treatment without fertilization was used as a control. Postharvest treatments included plastic packaging (PP), hydrocooling (HC), blanching (B), and edible coating of psyllium seed mucilage (EC). After postharvest treatments, celery petioles were stored (0–2°C, 85%–90% RH) for 4 weeks and evaluated weekly for quality attributes. Organic fertilizers and UREA_LOW were the most effective treatments in reducing the changes in color, weight loss, titratable acidity (TA), pH, and total soluble solids (TSS) of fresh‐cut celery. Organic fertilizers enhanced the vitamin C content, total phenols, and antioxidant activity in celeries. As postharvest treatments, hydrocooling, plastic packaging, and blanching maintained chroma and hue values. Blanching had the greatest effect on the L* value. Hydrocooling increased celery's TA, TSS, and vitamin C content and reduced weight loss and pH during storage. Thus, celery quality was improved when grown under low or adequate N fertilization. Hydrocooling was an effective postharvest treatment for preserving fresh‐cut celery quality during storage.
