The effect of electron beam (EB) irradiation on inactivation of foodborne microorganisms and the quality of whole egg powder (WEP) was investigated. WEP sample was irradiated (0, 1, 2, and 4 kGy) and stored for 2 months at 25°C. The values for , , and Typhimurium were 0.26, 0.13, and 0.26 kGy, respectively. The L* value increased, while the a* and b* values decreased with increasing irradiation dose. Foaming ability of irradiated samples increased at 0 and 1 months, but not at 2 month. The peroxide value of sample increased both with irradiation and storage. After 1 and 2 months, samples irradiated at 2 and 4 kGy had lower sensory scores for color than those irradiated at 1 kGy. These results suggested that the use of low-dose EB irradiation (≤2 kGy) could improve microbial safety and foaming ability of the WEP with minimal quality changes.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus is the causative agent of the emerging zoonotic respiratory disease. One of the most important prerequisites for combating emerging diseases is the development of vaccines within a short period of time. In this study, antigen-irradiated, inactivated SARS-CoV-2 viruses and the disaccharide trehalose were used to enhance immune responses in the Syrian hamster.

In this study, minced turkey meat samples were subjected to electron-beam irradiation with dosages of 0, 1.5, 3, and 5 kGy, and then microbial (mesophilic and psychrotrophic bacteria), physiochemical (pH, water activity [a], thiobarbituric acid reactive substances [TBARS], and peroxide value [PV]), and sensory (color, odor, texture, and overall acceptability) analyses were performed at 0 and 6 months of freezing storage (-18°C). Results showed that by 5 kGy irradiation and freezing treatments, the counts of psychrotrophic and mesophilic bacteria reduced remarkably ( < 0.

This study investigates the negative impact of climate change on water resources, specifically water for agricultural irrigation. It describes how to optimize swelling, gel properties and long-term water retention capacities of Na-CMC/PAAm hydrogels for managing drought stress of Sugar beet plants through techniques such as changing the composition, synthetic conditions and chemical modification. Gamma radiation-induced free radical copolymerization was used to synthesize superabsorbent hydrogels using sodium carboxymethyl cellulose (Na-CMC) and acrylamide (AAm).

Fusarium solani biomass plays a significant role in water pollution remediation due to its ability to sequester heavy metals, particularly cobalt (Co(II)) and cadmium (Cd(II)), which pose severe environmental and health risks. This study aimed to identify fungi from sewage-contaminated sites and evaluate their efficiency in absorbing and reducing Co(II) and Cd(II) ions. The biosorption potential of irradiated Fusarium solani biomass for removing Co(II) and Cd(II) ions from aqueous solutions was investigated.
