Reticulatus Naud) group Inodorus that were coated with a multilayered coating system using a polypropylene tray (Ziploc â) with (i) Ziploc â lid, (ii) Saran â wrap and (iii) plain cheesecloth and stored at 4°C for 15 days. The multilayered antimicrobial coating improved the shelf life of fresh-cut melon (up to 15 days), compared with the controls (7 days). Coated samples were firmer, maintained colour and total carotenoids content and showed less weight loss than the controls (P < 0.05). Among the packaging treatments, the Ziploc â lid was the most effective in maintaining shelf life. This study demonstrates the application of a new generation of edible coating using natural antimicrobial agents by means of the layer-by-layer assembly.

Cantalupensis Naud.) stored for 20 days at 4 C. Coating improved (P < 0.05) samples' firmness, colour, soluble solids, total vitamin C and carotenoid content for up to 15 days of storage, thereafter samples showed signs of decay with softening of processed melon resulting from structural changes in both biological membranes and cell walls. Coating also reduced hydrogen peroxide radical levels leading to lower antioxidant enzymatic activity and lipid peroxidation degree and electrolyte leakage levels compared with control. Coating improved produce visual quality due to reduction in the activity of browning-associated enzymes, G-POD and PPO. Results indicate that coating improved quality of fresh cut Cantaloupe melons by acting as a physical barrier to gas exchange decreasing respiration rate and consequently, O 2-dependent processes, while trans-cinnamaldehyde acted as free radical scavenger and enzyme inhibitor. The lower respiration rate inhibited the establishment of an oxidative stress induced by fruit processing and senescence with less damage to biological membranes, lower cell wall hydrolase activities and loss of bioactive compounds. 2015 Elsevier B.V.

Reticulatus Naud) group Inodorus that were coated with a multilayered coating system using a polypropylene tray (Ziploc®) with (i) Ziploc® lid, (ii) Saran® wrap and (iii) plain cheesecloth and stored at 4 °C for 15 days. The multilayered antimicrobial coating improved the shelf life of fresh-cut melon (up to 15 days), compared with the controls (7 days). Coated samples were firmer, maintained colour and total carotenoids content and showed less weight loss than the controls (P &lt; 0.05). Among the packaging treatments, the Ziploc® lid was the most effective in maintaining shelf life.
