This work investigates the potential application of e-beam radiation for sterilization of food packaging made of commercial polyester blend of poly(butylene adipate-co-terephthalate) and polylactide known under the trade name Ecovio 23B1. Ecovio film was irradiated at doses of 5, 13, and 26 kGy and the effect of sterilization on the microorganism inactivation ability was performed. The influence of radiation doses on structural and packaging properties such as tensile strength, barrier, and migration properties was also studied. 1 H NMR and FTIR analysis revealed no significant changes in the polymer structure, however, the molar mass of irradiated samples decreased with increasing radiation dose. This result indicated the occurrence of degradation process during radiation, which was confirmed by the thermal analysis and accelerated enzymatic degradation. The packaging properties did not changed significantly and the overall migration for 10% ethanol, isooctane, and MPPO was below the limit for all of the studied samples.

“…The use of gamma irradiation has long history in different types of food such as citrus (Mahrouz et al, 2002;Oufedjikh, Mahrouz, Amiot, & Lacroix, 2000;Oufedjikh, Mahrouz, Lacroix, Amiot, & Taccini, 1998), spices (Khatun et al, 2017), and vegetables (Majeed et al, 2017). Also gamma irradiation because of high penetration power is commonly used in food packaging that of course it is considered as a method for cold sterilization (Madera-Santana, Mel endrez, Gonz alez-García, Quintana-Owen, & Pillai, 2016). The level of changes caused by the ray in different foods in the aroma, color, and taste depends on the food material, irradiation dose, and ray source (Oliveira, Sousa-Gallagher, Mahajan, & Teixeira, 2012b).…”

This study was conducted to examine the combined method of gamma irradiation doses (0, 1, and 2 kGy) and Ag nanoparticles polyethylene films on the quality of fresh bottom mushroom during storage. For this purpose, physical and chemical properties such as pH, color, weight loss, as well as texture parameters test of the mushroom samples were measured and microbial tests for Ag nanoparticles polyethylene films were also performed during 21 days of storage at 4 °C. It was observed that the samples irradiated with a dose of 2 kGy and placed in Ag nanoparticles polyethylene films had the lowest reduction in pH (14.33%) and L* (lightness; 6.0%), while weight loss, b* and browning index had the fewest changes with the amount of 9.47, 5.58, and 13.84, respectively. Also, a*, for the control sample and Ag nanoparticles polyethylene films after 21 days of storage increased up to 8.39 and 7.17%, respectively, compared to the initial samples. Also, the greatest changes in the firmness and elasticity for the treatment, respectively were 5.22 and 3.24% compared to the initial samples. Finally, it has been indicated that Ag nanoparticles polyethylene films could prevent the accumulation of microbial load. The results thus demonstrate that the combined use of gamma irradiation and Ag nanoparticles polyethylene films is an effective approach to maintain the quality of fresh bottom mushroom during storage. Practical applications Irradiating food causes changes in flavor, color, nutrients, taste, and other qualitative properties and such merits could extend the shelf life of the food products for preservation aims. Also, use of nanoparticles polyethylene films could help to better preservation of the mushrooms. Such combinations (nanoparticles films with gamma rays) could be of interest for the industry in packaging process and consequently export for long time consumption.

“…chromatographic, spectroscopic, gravimetric) analytical methods can be used. In literature (Madera-Santana et al, 2016;Salafranca et al, 2015), several approaches were used to study the impact of γ-irradiation on multilayer films, as ion chromatography to detect and quantify the ionic species, and as pH and conductivity measurements to observe the consequences of the chemical modifications. γ-irradiation on multilayer films leads to chemical modifications, which their correlation is achieved using chemometric methods.…”

The impact of γ-irradiation on polymers in multilayer films was studied by means of the study of the diffusion and release (spontaneous migration of the molecules from the container into the product) of chemical species in aqueous solution. A series of different measurements have been performed: pH, conductivity, total organic carbon (TOC) and ion chromatography (IC). Their evolution according to γ-irradiation dose was studied. More several rinsings made over several months allowed to quantify well the impact of the irradiation on these polymers. The samples are irradiated at several γ-doses, up to 270 kGy, and compared with a non-irradiated sample used as reference. It shows that quantity of generated carboxylic acids depends on the film material (PE/EVOH/PE and EVA/EVOH/EVA) and increases with γ-dose.
