Active and Intelligent Packaging for Reducing Postharvest Losses of Fruits and Vegetables

Effects of Genotype and Modified Atmosphere Packaging on the Quality of Fresh-Cut Melons

“…The difference in the atmosphere composition between the active and passive MA packages was evident during the first week of storage, while during the second week, the packages of the same perforation level reached similar steadystate concentrations of oxygen and carbon dioxide, irrespective of their initial atmospheric compositions. This observation was in line with the model prediction that the steady-state O 2 and CO 2 levels in MA packages depend on the product's respiration rate and the packaging material's permeability, but not on the initial atmosphere [23,24]. On the other hand, the initial atmosphere determined the conditions during the transient period and its duration.…”

“…At first glance, the idea of combining the active MAP technique with micro-perforated packaging (micro-perforated active modified atmosphere, or MAMA packaging) seems paradoxical because it allows for a partial escape of the injected gas mix through perforations. However, it in face allows the MAP to be stabilized without a risk of hypoxia [24]. The positive effects of micro-perforated active MAP on produce preservation have been demonstrated with fresh-cut strawberries [23], cabbage [42], litchi [43] and rocket leaves [44].…”

“…In this study, we compared passive and active MAs as a means of preserving fresh-cut melons of two genetic types: inodorus and cantalupensis. Furthermore, the performance of the novel approach of MAMA packaging combining active MA with micro-perforation [24] was tested with fresh-cut melons. The difference in the atmosphere composition between the active and passive MA packages was evident during the first week of storage, while during the second week, the packages of the same perforation level reached similar steadystate concentrations of oxygen and carbon dioxide, irrespective of their initial atmospheric compositions.…”

“…However, it does not eliminate and even aggravates the risk of hypoxia in the packages of highly respiring produce. The approach of micro-perforated active modified atmosphere (MAMA) packaging combines an active MA with the use of laser-micro-perforated plastic films in order to minimize the transient period and at the same time prevent hypoxia [23,24].…”

Effects of maturity level, steam treatment, or active packaging to maintain the quality of minimally processed mango ( Mangifera indica cv. José)

“…A more potent way could be to combine the used films with modified atmosphere packaging (Shinde et al, 2018) or to include antibrowning agents like ascorbic or citric acid in films for an enhanced effect (Barbagallo et al, 2012;Robles-Sánchez et al, 2009.…”
