“…Results showed that the PLA containers prolonged blueberry shelf life at different storage temperatures. Del Nobile et al [47] used four different films: two polyester-based biodegradable films, a multilayer film made by laminating an aluminium foil with a polyethylene film and an oriented polypropylene film to study the ability of biodegradable films to prolong the shelf life of minimally processed lettuce stored at 4°C. Results suggest that the gas permeability of the investigated films plays a major role in determining the quality of the packed produce.…”

Modified atmosphere packaging (MAP) of fresh produce relies on the modification of atmosphere inside the package achieved by the natural interplay between two processes: the respiration rates of the commodity and the permeability of the packaging films. MAP has been a proven technology to meet the consumer's demand for more natural and fresh foods, which is increasing day by day. Because of its dynamic phenomenon, respiration and permeation take place simultaneously, and it is necessary to design the MAP system and select the matching films to achieve desired atmosphere early and maintain as long as possible. To meet the desired film characteristics for MAP, the different plastic films are either laminated or coextruded. In this modern world, the packaging films of required gas transmission properties are made available through advanced technology. Although the MAP industry has an increasing choice of packaging films, most packs are still constructed from four basic sustainable polymers: polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyproylene (PP) and polyethylene (PE) for packaging of fresh produce. Polystyrene has also been used but polyvinylidene, polyester and nylon have such low gas permeabilities that they would be suitable only for commodities with very low respiration rates.

“…In previous studies, different kinds of methods have been developed in order to retain the freshness of fresh-cut lettuce or other vegetable (Del Nobile et al, 2008;Kasim & Kasim, 2015;Martín-Diana et al, 2008;Zhang et al, 2006). Plant hormone is a kind of naturally produced small molecular residues, which has been proven to be closely associated with plant development and stress resistance (Wang et al, 2014).…”

Postharvest lettuce often lose water, thus affecting both its market value and consumer acceptance. However, the mechanism of the water-loss is still waiting well exploration. The aim of the present study was to investigate the effect of a foliar application of ABA on the fresh weight-loss and the chlorophyll content of postharvest lettuce as well as its association with the regulation of stomata. The present data demonstrated that exogenously application of ABA, in a concentration range of 0 to 100 µM, significantly lowered the fresh weight-loss of postharvest lettuce. ABA also delayed chlorophyll reduction during ambient storage, but this protective effect was ABA concentration-dependent. Among the tested ABA concentrations, 50 µM or lower ABA produced an inhibition effect on chlorophyll degradation in postharvest lettuce leaves. The results demonstrated that the exogenous ABA treatment can obviously reduce the transpiration rate of lettuce leaves by promoting the stomatal closure of postharvest lettuce, therefore eventually delay fresh weight-loss. The present study primarily showed that the application of exogenous ABA, which originated from a naturally-produced phytohormone, has a great potential in retaining the freshness of postharvest lettuce that is stored in an ambient condition, although possible practical application still need to be further evaluated.Keywords: lettuce; postharvest; abscisic acid; water-loss; stomatal closure. Practical Application:The effect of a foliar application of ABA on postharvest lettuce was investigated. The results demonstrated that the ABA, which originated from a naturally-produced phytohormone, can obviously reduce the transpiration rate of lettuce leaves by promoting the stomatal closure of postharvest lettuce, therefore eventually delay fresh weight-loss and chlorophyll reduction during ambient storage. The strategy could potentially be used as an alternative for lettuce producer and retailer to effectively retain the fresh of postharvest lettuce products.

“…Their complete substitution with more eco-friendly polymers is difficult, however, the utilization of biodegradable systems in specific food packaging sector such as readyto-eat food, could be possible (Siracusa, Rocculi, Romani, & Dalla Rosa, 2008). A few applications of bio-based films to ready-to-use fruit and vegetables have been reported in the literature; moreover, the different characteristics of every product need to tailor a specific packaging for each of them Del Nobile, Baiano, Benedetto, & Massignan, 2006;Del Nobile, Conte, Cannarsi, & Sinigaglia, 2008;Del Nobile, Licciardello, Scrocco, Muratore, & Zappa, 2007;Del Nobile et al, 2009). For this reason, the potential application of a bio-polymeric film, compared to traditional oriented polypropylene, was investigated on ready-to-eat sweet cherries packaged under ordinary and modified atmosphere conditions.…”
