Treatment with ozone, radiation, microwave and vacuum mixing were reported as the new technologies enhancing shelf life or quality of fresh noodles.
Treatment with ozone, radiation, microwave, photons and vacuum mixing, as well as packaging methods such as vacuum packaging, MAP, active packaging and hot-online packaging have been employed to manufacture fresh noodles or CSB with significantly extended shelf life.
Manipulating production process and storage conditions, such as physical treatments with ozone, radiation, microwave, photons and vacuum mixing as well as packaging methods including vacuum packaging, modified atmosphere packaging (MAP), active packaging and hot packaging, showed promising results for enhancing the shelf life of fresh noodles and CSB [2, 12, 21, 33 35].
Reactive oxygen species (ROS) are continuously formed as a by-product of metabolisms in aerobic organisms and are also produced on exposure to tobacco smoke, ozone, radiations, organic solvents, and other environmental pollutants [ 1].
Skin, a biological environmental interface having a barrier function, is a potential target organ for oxidative stress by external offenders, such as UV irradiation, ozone, ionizing radiation, and various toxic chemicals [ 1].
To avoid those risks, some water-treatment plants use ozone, ultraviolet radiation, or hydrogen peroxide disinfection instead of chlorine.
Without a fresh supply of ozone, solar radiation triggers reactions inside the vortex that can burn a hole in the ozone layer, as it regularly does over the Antarctic.
However, the factors that best explained the excess attendances with this outcome in April-May 2005 were likely to be of photochemical origin, given the observed associations with ozone, solar radiation and temperature during that period.
Though it is known for high oxidative and biocidal efficiency, the use in drinking water disinfection is not available, but coupled with ozone, UV-radiation it can be used (Andreozzi et al. 1999).
Outside the Earth's protective ozone layer, ultraviolet radiation will rapidly give unshielded space travelers sunburn and skin cancer.
Of course water is filtered and treated, for example, with chlorine, ozone and ultraviolet radiation before it makes its way to people's faucets, but hazards still remain.
