Global food scientists are now recommending the use of ozone which is being viewed and recognised as a promising food processing agent.
Ozone is increasingly accepted as an environment-friendly technology. The multi-functionality of ozone makes it a promising food processing agent. Excess ozone decomposes rapidly to produce oxygen and this leaves no residue in foods from its decomposition, according to Brijesh Tiwari, researcher, food and consumer technology, Manchester Metropolitan University and School of Food Science and Environmental Health, Dublin Institute of Technology.
In particular, the USFDA rulings on ozone usage in food have resulted in increased interest in potential food applications worldwide. Ozone as an oxidant is used in water treatment, washing and disinfection of equipment, odour removal and fruits vegetable, meat and seafood processing.
The key drivers of ozone usage in the food industry are regulation, surface cleanings, food safety, nutrient, sensory aspect, technology advances and shelf life extension, he stated in a presentation on—Ozone a leading food processing technology—here recently.
