Sterilization is defined as any process that effectively kills or eliminates almost all microorganisms like fungi, bacteria, viruses, spore forms. There are many different sterilization methods depending on the purpose of the sterilization and the material that will be sterilized. The choice of the sterilization method alters depending on materials and devices for giving no harm. These steriliz...

TThis study investigated the water absorption of chitosan, collagen, and chitosan/collagen blend membranes exposed to gamma-ray irradiation. These membranes were produced via the solvent evaporation method. All membranes then underwent irradiation at 15 or 25 kGy gamma-ray doses, while membranes without irradiation were used as controls. After immersing the membranes in distilled water for up t...

To study the control of postharvest decay caused by Colletotrichum gloeosporioides and Penicillium expansum, gamma irradiation alone or in combination with fumigation was evaluated to extend the shelf life of apples in South Korea. An irradiation dose of 2.0 kGy resulted in the maximum inhibition of C. gloeosporioides and P. expansum spore germination. The gamma irradiation dose required to red...

the objective of this study was to determine the effect of irradiation of pomegranate seed (ps) on chemical composition, digestibility and kinetic of gas production. pomegranate seeds were exposed to gamma ray (gr) and electron beam (eb) at doses of 5, 10, 15 and 20 kgy. three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...

introduction native rapeseed (nrs) is planted in some parts of iran because of climatic condition. the consumption of nrs in animal nutrition is limited by anti-nutritional such as phytic acid and glucosinolate. moreover, the protein of nrs is highly degraded by rumen microorganisms. several processing methods have been used to enhance the nutritive value of whole oilseeds, including extrusion,...

The effects of gamma irradiation, stearic acid alone and in combination on functional, structural and molecular characteristics of high amylose maize starch (Hylon VII) were studied. Stearic acid (0, 1.5 & 5 %) was added to Hylon VII starch, and then irradiated at 0, 30 and 60 kGy. Gamma irradiation significantly (P ≤ 0.05) increased solubility, water absorption capacity and oil absorption capa...

background: the present study has been carried out to investigate the effects of preovulatory stage gamma-irradiation of female mice in the absence or presence of vitamin e on numerical chromosome abnormalities in 8-cell embryos after mating with non-irradiated males. materials and methods: the 8-11 weeks adult female nmri mice were whole body irradiated at preovulatory stage (post pmsg injecti...

Gamma irradiation is a nonthermal processing technology that has been used for the preservation of a variety of food products. This technology has been shown to effectively inactivate bacterial pathogens. Currently, the FDA has approved doses of up to 4.0 kGy to control food-borne pathogens in fresh iceberg lettuce and spinach. However, whether this dose range effectively inactivates food-borne...
