Technology of food processing by e-beam accelerator

Electron-beam (or e-beam) is a stream of high-energy electrons propelled from an electron accelerator into food. At first, electron-beam accelerator generates and accelerates electrons close to light velocity, then electrons go directly into the products surface and destroy DNA of microbes, bacteria, insects etc. therefore the products are sterilized and shelf life of products is increased in many times.

Sterilization of medical equipment ensures complete destruction of microorganisms and undesirable bacteria in the material. There is no risk of recontamination because all medical equipment and instruments are processed in package. Sterilization by e-beam accelerator facility of food products helps to completely destroy all pathogenic bacteria, such as Salmonella, Campylobacter, Escherichia coli, Listeria, Bacillus cereus and also all dangerous insect-pests, such as Grain weevil, Corn borer, Saw-toothgrain beetle, Drosophila (fruit fly), fungi, mold and many other pathogenic microorganisms, which prevents food spoilage and increase shelf life of food products.

During the processing of food products by e-beam accelerator implementation of radioactive isotopes is excluded, which provides their safety. Sterilization facility is electrically powered. The process is relatively fast and totally safe; there is no residual radiation in the food products after irradiation, so they can be handled immediately after the treatment. This is absolutely harmless sterilization method that does not affect organoleptic qualities of food product, taste and color remain unchanged.
Safety and efficiency of e-beam sterilization method
No Cobalt-60
No residual radiation in the food product after irradiation
Absolute destruction of microorganism, shelf life of food products increases
Organoleptic properties of food products remain unchanged after sterilization
High bactericidal resistance of medical equipment after sterilization
Ecologically friendly method
Sterilization of food products does not affect organoleptic properties; color and taste remain unchanged, because e-beam sterilization method is attended with low level of energy and does not cause significant biochemical transformations in it. There is no residual radiation in food product after sterilization. Electron-beam sterilization method maintains nutrition value of food products after processing and provides guaranteed quality with longer shelf life. Proteins, fats and carbohydrates undergo very little modify in nutritional value through irradiation. In the same way, the essential amino acids, essential fatty acids, minerals and trace elements are also unchanged. There can be a decrease in certain vitamins (mostly thiamin) but these are of the same order of magnitude as occurs in other manufacturing processes such as drying or canning.
The method is completely safe and harmless. There is a Guaranteed level of bactericidal action of medical equipment after sterilization. All pathogenic microorganisms such as spores etc. inside the material are died, which makes it safe for clinical image.

What is ionising sterilization?
It is the sterilizing process that employs a source of energy capable of ionizing the atoms in the molecules that constitute materials.
How does the ionization energy works on the sterilization process and microbial load reduction?
The ionizing radiation breaks the microorganisms DNA chain, killing them or rendering them incapable of reproducing themselves.
Do the treated products become radioactive?
Processing by electron beam radiation does not leave residual radiation when processed in the electron beam mode with energy up to 10 MeV, and in X-ray mode with energy up to 7.5 MeV.
In which case is e-beam technology indicated?
The process can be used to disinfect, decontaminate or sterilize different types of products in order to improve the safety of the treated product. It is also useful to improve the physicochemical and mechanical propertiesof certainmaterials. There are no restrictions to itsapplication, but tests should be carried out in order to establish the correct dosage of energy to be applied to the product that is going to be processed. Due to its high penetration capacity, this technology is indicated for products from low to high density, allowing them to be treated inside their final packaging, no matter the number of package layers or the packaging geometry.
How does the e-beam technology work, and in what situation is it indicated?
The radiation process by e-beam facility, exposes the products to beams of accelerated electrons with high energy. The electrons lay downtheir energy on the products, causing the "molecule ionization", essential to achievethe expected result. The process can be used to disinfect, decontaminate or sterilize different types of products in order to improve the safety of the treated product. Another very important application of electron beams is material modification, as the reticulation reaction in polymers. The technology is more suitedfor processing products with low density.However, its suitability for products with other properties has also been demonstrated.
Which are the types of microorganisms and in which stages of their development are this technologies effective?
The technologies are effective for all kinds of microand macroorganisms(insects) in anystage of development. Some microorganisms are more sensitive than others, and for this reason, tests should be carried out to obtain the correct energy dosage.

What is a ionizing radiation dose?
It is the amount of energy absorbed by the product being treated by ionizing radiation. The measurement unit is the KGy (Kilogray), which is determined by the time the product is exposed to the ionizing radiation.
Which are the criteria for defining the sterilization dose?
The definition of sterilization dosage is based on two criteria:
1. The information about initial microbial load for the product, i. e., the initial contamination
2. The expected result in terms of reduction of microbial load or sterility.
What is the ideal temperature for carrying out the process? Can frozen, chilled, or thermosensitive products be treated?
The processes normally don't result in high temperature changes. The temperature variation during the processis around 3ºC. All products can be treated normally. In the gamma ray process, there is no restriction.
Does the process generate any radioactive residues?
No radioactive residues are generated during the process.
Does the process require that treated products be put into quarantine?
No, it does not. The products can be used immediately after processing.
Can the product be treated inside its final packaging?
Yes. There are no package related restrictions.
Can processes be validated?
Yes. ISO 11137 is recommended.
