“…In this regard it is also considered that the rate of respiration reduced by edible coatings may delay the utilization of organic acids present in the fruit [34]. Coating slowed the changes in pH and TA in banana fruit by effectively delaying fruit senescence, as reported by Gol and Rao [35]. Similar findings were obtained by Aguiar et al, who reported that mango fruit treated with galactomannan coating retained TA at a higher level as compared with uncoated samples [36].…”

“…Based on these results, it was concluded that NCC/CS composite coatings formed an excellent semipermeable film around the cucumber, modifying the internal atmosphere by reducing O 2 and/or elevating CO 2 , and suppressing ethylene evolution, which might slow down the respiration and metabolic activity, hence retard the ripening process (Dong et al 2004). TSS content of coated fruits was reported previously through use of CS-based films and cellulose derivatives-based films (Malmiri et al 2011;Ali et al 2011;Gol and Rao 2011).…”
Nanocellulose/chitosan composite coatings are useful for their mechanical and barrier properties, biodegradability, and food safety applications. The aim of this study was to investigate the effects of 1% chitosan (CS) and 5% nanocellulose (NCC) composite coatings on cucumber. The influence on quality and antioxidant enzymes were investigated by immersing cucumbers in deionized water (CK), chitosan solution (CS), and nanocellulose/chitosan composite solution (NCC/CS), respectively, during a 14-day storage at 4 C. At the end of storage, weight loss of cucumbers in NCC/CS decreased to 8.4%, and firmness reduced by 20.3%. Chlorophyll degradation was noticeable in visual appearance and lowered by 25.5%, there was no marked change in ascorbic acid content. Total soluble solids decreased 0.78%. The enzymatic activities responsible for softening phenomena including catalase (CAT) and peroxidase (POD) activity fell 25.6% and 16.1%, respectively. Alterations were more apparent in CK cucumbers. The results confirm that the use of NCC/CS composite coatings might maintain quality and extend the shelf life of cucumbers.
“…The positive effect of chitosan coating on a storage life of fruits could due to the modifying the internal atmosphere of fruits. The modified atmosphere created with edible coating that was delay the ripening by declining the ethylene production and by reducing the level of internal oxygen and consequently extending the storage life of fruit (Gol and Rao, 2011). Bosquez-Molina et al, (2010) also reported that mesquite gum coatings comprising thyme and Mexican lime oils reduced fruit decay occurrence resulting from C. gloeosporioides and R. stolonifer in papaya during storage, whereas the untreated fruit completely decayed.…”
