Below is a great article on the use of ozone in food storage. \u00a0For more info on food processing and food storage see our website by clicking here.<\/a>Ozone use in cold storage facilities, transport containers, and off the field storage will help prolong shelf life of foods, and helps achieve and maintain an organic rating.Many applications still use methyl bromide or other harmful chemicals. \u00a0Ozone use replaced methyl bromide and achieves the same results for pest and bacterial control in food applications.See complete original article HERE<\/a><\/p>\n

Postharvest diseases reduce the value and quality of agricultural products, leading to economic losses for growers and producers. This is a major issue for agricultural countries like Malaysia, which exports papaya. Current technologies such as synthetic fungicides help minimise these losses, although potential risks to human health and the ecosystem restrict the use of such chemicals.<\/p>\n<\/div>\n

<\/div>\n

Led by Professor Asgar Ali, researchers at the Centre of Excellence for Postharvest Biotechnology at the University of Nottingham Malaysia Campus are currently exploring the potential of ozone as a safer alternative to synthetic fungicides. This technology could help maximise profits for producers while improving the safety and quality of agricultural products<\/a> for consumers.<\/p>\n

“It is saddening that current practices are too dependent on the use of synthetic chemicals \u2013 no doubt due to their effectiveness. But our health should come into consideration as well,” says Professor Ali.<\/p>\n

To test the effects of ozone, the team exposed freshly harvested papaya to gaseous ozone for 96 hours and then stored it at cool temperatures for 14 days. The results showed that ozone-treated papaya had higher antioxidant activity and higher levels of ascorbic acid, beta-carotene and lycopene than untreated papaya.<\/p>\n

Professor Ali’s team also found that ozone treatment can delay and decrease the incidence of anthracnose, a common postharvest disease of papaya, by inhibiting the growth of microorganisms on the surface of the fruit. Ozone is also effective at removing fungicide residues.<\/p>\n

Further study confirmed that ozone has similar antimicrobial effects on freshly cut fruits and vegetables, which are generally more exposed to bacterial contamination during the cutting process.<\/p>\n

Professor Ali’s team is currently working in collaboration with healthcare technology supplier MedKlinn International to further research on ozone treatment as a safer alternative for food protection. This collaboration will look into the commercialisation of ozone treatment with some fruit and vegetable growers and exporters. MedKlinn will supply an ozone chamber to these groups as a pilot project while Professor Ali’s team will provide technical expertise. This collaboration aims at targeting the fruit and vegetable export companies in Malaysia and recommending the use of ozone treatment<\/a> as a safe alternative to the control of postharvest anthracnose.<\/p>\n<\/article>\n<\/section>\n<\/section>\n

Ozone Can Protect Exotic Fruits from Disease, Decay<\/span><\/h2>\n

Malaysian researchers are developing an ozone treatment to protect papaya and other exotic fruits from diseases and decay during storage and transportation.<\/p>\n
