Electron-beam processing has the ability to break the chains of DNA in living organisms, such as bacteria, resulting in microbial death and rendering the space they inhabit sterile. E-beam processing has been used for the sterilization of medical products and aseptic packaging materials for foods, as well as disinfestation, the elimination of ...
Fluids that would be damaged by heat, irradiation, or chemical sterilization, such as drug solution, can be sterilized by microfiltration using membrane filters. This method is commonly used for heat labile pharmaceuticals and protein solutions in medicinal drug processing.
Equipment used in aseptic processing of food and beverages must be sterilized before processing and remain sterile during processing. [1] When designing aseptic processing equipment there are six basic requirements to consider: the equipment must have the capability of being cleaned thoroughly, it must be able to be sterilized with steam, chemicals, or high-temperature water, sterilization ...
The international Radura logo, used to show a food has been treated with ionizing radiation. A portable, trailer-mounted food irradiation machine, c. 1968 Food irradiation (sometimes American English: radurization; British English: radurisation) is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams.
Microwave irradiation is based on the principle of generation of high frequency waves. These waves cause the particles within the waste material to vibrate, generating heat and killing the pathogens from within. A simple yet effective method is chemical disinfection: 1% hypochlorite can kill thriving bacteria. Plasma pyrolysis is an environment ...
Irradiation is the process by which an object is exposed to radiation.An irradiator is a device used to expose an object to radiation, [1] most often gamma radiation, [2] for a variety of purposes.
The Radura symbol was created by inventors from the former Pilot Plant for Food Irradiation in Wageningen, Netherlands, which later evolved into the company known as Gammaster, now called Isotron. The plant's director at the time, R.M. Ulmann, introduced the symbol to the global community.
There are three types of exchangers in use: [15] Plate exchangers, Tubular exchangers; Scraped-surface exchangers. For higher efficiency, pressurized water or steam is used as the medium for heating the exchangers themselves, accompanied with a regeneration unit which allows reuse of the medium and energy saving.
