“…A lot of work has been and is still performed to evaluate the suitability of the ionizing irradiation on food packaging materials or prepackaged foods [30][31][32][33][34][35][36][37][38][39][40]. As Chmielewski recognizes, the use of processing materials by radiation is at present a wellknown technology and continues to advance constantly in many industrial sectors [41].…”

The environmental damage human activities are cause is our most present concern. Plastics mainly petroleum-based packaging materials are widely employed in the manufacture of food packaging because of their performance and facility of production. That is leading to serious ecological problems for the environment as synthetic plastics are resistant to biodegradation. Biopolymers can be seeing as a solution to the problems posed by plastics as they easily degrade in the environment. Naturally occurring polymers produced by living organisms show no adverse effects on the environment or human being. For biodegradable food packaging it is required to employ biopolymers with good film formation capability and to employ a proper film formation method. In the present article, the employment of radiation technology in the production of films or coating for food packaging is presented as a novel application.

“…International standards for radiation sterilization ask for evidence of a minimum dose of 25 kGy induces irreversible structural changes in many materials (Karina et al 2018). Radiation sources like Co-60 and Cs-137 can release high-energy electromagnetic gamma rays and effectively eliminates contaminating microorganisms (Silindir and Özer 2009).…”

Paper sheets represent one of the infection risk sources inside many institutions. The present study aimed to validate the sterilization efficiency of contaminated paper sheets with different indicator pathogens by gamma radiation or dry heat technique with retaining their structure. The results show that gamma irradiation at 6 kGy, 12 kGy, and 24 kGy can successfully kill Gram-positive bacteria like Bacillus cereus and Staphylococcus aureus, Gram-negative bacteria like Escherichia Coli and Salmonella typhi, and fungi such as Candida albicans. Moreover, dry heat at 100°C for 1 hour, 150 for 30 min, or 200 for 15 min can be successful in paper decontamination completely all tested species. Surprise, micrographs of scanning electron microscope (SEM) proved that a radiation dose of 6 kGy, dry heat at 100°C for 1 hour, 150 for 30 min or 200 for 15 min is suitable for paper sheets sterilization with maintaining their structure. Ultimately, dry heat or γ-radiation as simple, useful, effective, fast, safe, and inexpensive techniques. It may be used as a precautionary step inside educational institutions especially, during written examinations period to ensure safe life for academic members during biological pandemics like covid-19.

“…Some of the polymers (both natural and synthetic) treated with superheated steam, hot air or high temperature undergo deformation, thermal and oxidative degradation and in many cases hydrolysis if they are susceptible. In those circumstances better results might be provided by other methods such as: ethylene oxide [2], hydrogen peroxide [3], ethyl alcohol [4], gamma [5] and electron-beam (e-beam) radiation [6], plasma [7]. Moreover, the process of choosing the right method is even more complicated, if we look for the sterilization technique dedicated for food packaging.…”

Effect of Electron-Beam Radiation and Other Sterilization Techniques on Structural, Mechanical and Microbiological Properties of Thermoplastic Starch Blend

This work investigates the potential application of various sterilization methods for microorganism inactivation on the thermoplastic starch blend surface. The influence of the e-beam and UV radiation, ethanol, isopropanol and microwave autoclave on structural and packaging properties were studied. All the applied methods were successful in the inactivation of yeast and molds, however only the e-beam radiation was able to remove the bacterial microflora. The FTIR analysis revealed no significant changes in the polymer structure, nevertheless, a deterioration of the mechanical properties of the blend was observed. The least invasive method was the UV radiation which did not affect the mechanical parameters and additionally improved the barrier properties of the tested material. Moreover, it was proved that during the e-beam radiation the chain scission and cross-linking occurred. The non-irradiated and irradiated samples were subjected to the enzymatic degradation studies performed in the presence of amylase. The results indicated that irradiation accelerated the decomposition of material, which was confirmed by the measurements of weight loss, and mass of glucose and starch released to the solution in the course of biodegradation, as well as the FTIR and thermal analysis.
