UV-C processing capability acquired
We have recently invested in an ultraviolet light tunnel system
for research and contract services. UV light treatment is a
non-thermal, non-chemical technology to inactivate
microorganisms, and has been used to disinfect water/air
systems and for surface decontamination (packaging and work
surfaces) for many years. In comparison, its application to
process foods, which is an area that we will be exploring, is a
relatively new and challenging area.
Our system consists of 16 x 95W high output UV-C emitters, where the product can be treated from both above and below.
Although all UV wavelengths cause some photochemical effects, wavelengths in the UV-C range (100-280nm) are particularly damaging to cells because they are absorbed by proteins, RNA, and DNA. Germicidal efficiency reaches a peak at about 254 nm. Treatment with ultraviolet energy offers several advantages to food processors as it does not leave a residue, and does not require extensive safety equipment. It is also easy to use and is relatively low on equipment, energy and maintenance costs.
