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 micro and macroorganisms (insects) in any stage 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 the 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 process is 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.
