Scientists developed a safe and cheap technology of disinfection of the packed eggs

It allows to kill bacteria and to raise healthy chickens with less dose of antibiotics

2021-04-02

(Press-News.org) Russian researchers have developed an inexpensive, safe, and reliable packed eggs surface disinfection technology. This technology helps to kill bacteria, including salmonella, on eggshells. Also, it allows growing broiler chickens with strong immunity to viral diseases. Packed eggs are disinfected with 50 nanoseconds (one billionth of a second) electron beam. Disinfection takes place in plastic containers. The description of the technology was published in Food and Bioproducts Processing. "Disinfection of the packed eggs protects eggs from subsequent contamination during storage", said Sergey Sokovnin, a professor at Ural Federal University and Ural Branch of Russian Academy of Science. "We found out that 5 kGy is enough for disinfection. Such dose allows to disinfect container and eggshells but does not affect the physical properties of the protein, yolk, and shell, or their composition. The size of the eggs does not matter." Disinfection does not affect the quality of meat and the volume of chicks. So, if 63% of chickens hatch from ordinary eggs, then from processed ones - 64%. But the difference is that healthy chickens emerge from the disinfected eggs. "86% of chickens from untreated eggs show signs of chronic inflammation. In chickens from irradiated eggs, this figure reached only 4%", said Sergey Sokovnin. "At the same time, chickens from the second group had an increased immunity to Newcastle disease. This is a bird's viral disease. It means that chickens from sterilized eggs will be less sick. And it will be possible to significantly reduce the dose of antibiotics when they are growing." The technology also saves time for industrial manufacturers. To hatch chickens from clean eggs, take about six hours less. Instead of the usual 22-24 hours, chickens appear in 16-18 hours. This is extremely important as it reduces production costs. "The accelerator capacity is 108 million eggs per year, which is enough for a large poultry farm", said Sergey Sokovnin. "It permits irradiation up to 40 eggs per second. The cost of irradiation of plastic packaging for 10 eggs was 1.2 Eurocents. If one technological line will operate in one shift of 250 working days a year, then the investment will be returned in five years. The main costs are staff salaries, overhead costs, equipment costs". There are no serious technical problems with the implementation of the technology. The small size of the accelerator makes it easy to integrate into existing lines for control and packaging of eggs in poultry farms. The technology, according to scientists, can also be used to disinfect the surface of eggs of other birds, as well as products with peels or another natural packaging (seeds, bananas, oranges).

Water quality also address to elements dissolved. In the case of fluoride, controlled amount are recommended for protect tooth, e.g. included in toothpaste. Higher levels can cause fluorosis, interfere in tooth enamel formation, correct growth of the bones, and cause crippling deformities of the spine and joints. The incidence of higher concentrations of fluoride in water is higher in rural areas without ...

Understanding itch: New insights at the intersection of the nervous system & immune system

2021-04-02

Eczema, or atopic dermatitis (AD), is sometimes called "the itch that rashes." Often, the itch begins before the rash appears, and, in many cases, the itchiness of the skin condition never really goes away. Approximately 9.6 million children and 16.5 million adults in the U.S. have AD, which can have a serious effect on quality of life for patients. Although much has been learned about the uncomfortable sensation that triggers the desire to scratch, many mysteries remain about chronic itch, making it a challenge to treat. A paper by authors from Brigham and Women's Hospital and Harvard Medical School published in The Proceedings ...

In-situ nanoscale insights into the evolution of solid electrolyte interphase shells

2021-04-02

The interfacial decomposition products forming the so-called solid-electrolyte interphase (SEI) during the first charging/discharging significantly determine the electrochemical performances of lithium (Li) batteries. To date, the dynamic evolutions, chemical compositions, stabilities and the influencing factors of the SEI films have been captured tremendous attentions. It's noted that, in contrast to the SEI film formation at the surface of electrodes, a kind of SEI shells usually conformally forms at the outmost layer of the on-site deposited Li once the freshly deposited Li contacts with the electrolyte, which could directly influence Li nucleation, growth behaviors ...

Commercially available ultralong organic room-temperature phosphorescence

2021-04-02

Purely organic room-temperature phosphorescence (RTP) materials have been a hot research topic. Currently, the pure RTP materials have been realized by the introduction of heavy halogen atoms, carbonyls groups or some heteroatoms, hydrogen bonding, H-aggregation, strong intermolecular electronic coupling, molecular packing, host-guest interaction, etc. However, the complicated synthesis and high expenditure are still inevitable in these systems. In addition, their performances in air are not satisfactory and the introduction of halogen atoms is generally necessary. Therefore, a new facile and robust host-guest strategy utilizing only electron-rich materials is a promising alternative for constructing RTP systems. Very ...

Oxygen-promoted synthesis of armchair graphene nanoribbons on Cu(111)

2021-04-02

On-surface synthesis has received great attention as a method to create atomically-precise one-dimensional (1D) and two-dimensional (2D) polymers with intriguing properties. In particular, graphene nanoribbons (GNRs), a category of quasi-1D nanomaterials derived from graphene, have been widely studied due to their tunable electronic properties and potential applications in semiconductor devices, such as field-effect transistors and spintronics. A series of top-down approaches have been pursued to produce GNRs, but a lack of control over the ribbon width and edge structure has hindered their further development. In 2010, Cai et al. firstly reported the fabrication of an atomically-precise armchair GNR (AGNR) on the Au(111) surface using a bottom-up ...

Realtime imaging of female gamete formation in plants

2021-04-02

Scientists from Nagoya University, Yokohama City University and Chubu University have developed a system which enables the live imaging of the formation of the female gamete in plants. In flowering plants, the sperm cell and egg cell meet and fertilization takes place in the flower. While sperm cells are made in the pollen, egg cells are made in the ovule, the structure that becomes the seed. However, as the ovule is buried deep within the pistil, it has thus far been impossible to observe the formation of the egg cell in living plants. The team, led by Dr Daisuke Kurihara and Dr Tetsuya Higashiyama of Nagoya University Institute of Transformative Bio-Molecules (WPI-ITbM), Dr Daichi Susaki of Yokohama City University Kihara Institute for Biological Research ...
