Food Disinfection

Food Disinfection

INTRODUCTION

Summary:
Cold-chain food contamination has been linked to COVID-19 outbreaks, including the June 2020 resurgence in Beijing’s Xinfadi Market. Cases like the Qingdao Harbor incident, where SARS-CoV-2 RNA was found on imported seafood packaging, show that cold-chain logistics can be hotspots for virus transmission. While the cold chain ensures product delivery and quality, it has traditionally neglected modern food safety protocols. These findings emphasize the urgent need to update cold-chain disinfection and safety standards to address current and future pathogen threats.

What ar Far UV 222nm excimer light tubes used for cold-chain disinfection?

Vendi222 Excimer Far UVC light is the very high-energy light generated by lamps containing noble gases or noble-gas hydride compounds.
Externally applying high-energy electrons to a sealed lamp containing a noble gas or noble gas hydride compound generates intense plasma discharge (dielectric barrier discharge).
This plasma features high-energy electron content and can be extinguished instantly.
The plasma discharge instantly excites the atoms of the discharge gas (noble gas) to their excimer (KrCl) state (high-energy orbital atoms form excimer excited molecules).
The excimer-specific spectrum is emitted when atoms return from this excimer state to their original condition (ground state).
This emission is called VUV light. Low-pressure mercury-free excimer Vendi222 tubes have a spectral peak at UVC 222 nm wavelength and emit more than 99% of their ultraviolet radiation at this peak in less than 3s.
These tubes are strong enough to the peak absorbance of DNA that they have high efficiency at damaging microbial DNA.

Is Cold Chain Far UV 222nm Light Disinfection Safe for Food?

… Recently, the food industry has shown increasing interest in the use of UV radiation for the decontamination of liquids and solid surfaces. It is considered one of the non-thermal inactivation interventions and is a physical method recognized for its germicidal efficacy with the potential to control foodborne pathogens, spoilage microorganisms and, viruses and bacteria. In addition, Far UV 222nm radiation is an intervention technology known as non-ionizing radiation as it provides no radioactivity to the product when compared to ionizing radiation (gamma radiation) that provides residual radioactivity (Datta & Tomasula, 2015; Park, Kang, & Kang, 2018). …

Why Sterilize Food by Use of UVC 222nm excimer light?

Sterilization can serve many purposes.

Prevention of Foodborne Illness – to effectively eliminate organisms that cause foodborne illness, such as Vovid-19, Salmonella, and Escherichia coli (E. coli).
Preservation – to destroy or inactivate organisms that cause spoilage and decomposition and extend the shelf life of foods.
Control of Insects – to destroy insects in or on tropical fruits imported into the United States.
Sterilization also decreases the need for other pest-control practices that may harm the fruit ( chemical).
Sterilization – irradiation can be used to sterilize foods, which can then be stored for years without refrigeration. Sterilized foods are useful in hospitals for patients with severely impaired immune systems, such as patients with AIDS or undergoing chemotherapy.

Far UV Light Aids Food Sterilization Applications

The FDA approved the use of food irradiation beginning in 1963 to treat yeast and flours to prevent insect contamination. Today, the USDA and FDA regulate food sterilization with UVC light on many products including raw poultry, red meats, fruits and vegetables, yeasts and flours and many beverage processing plants for juices and bottled water.

Far UVC 222nm excimer light food sterilization improves food safety, prolongs shelf life, prevents foodborne illnesses, controls insects, and even delays the early sprouting of potatoes and onions. You can find UVC germicidal lamps used for food safety in applications with many types of foods and beverages, including:

Meat, fish, and poultry
Dairy
Beverages
Liquid sugar tanks
Frozen foods
Baking
Fruits and vegetables
