Ozone treatment for Rice

Ozone Treatment May Help Thailand Restore Quality of Rice Stocks

A rice miller in Thailand’s Phichit province has come up with a brilliant idea of restoring the quality of decaying rice. The method called “Ozone Treatment” can used to restore the freshness of the grains and is considered safe for human consumption, according to local sources.

Under this technique, decaying and smelly old rice is first put into huge tanks and ventilated through air flow from fans to remove dust and impurities from the grains. It is then moved into another tank for drying with ozone by circulating more oxygen. Rice grains should be retained for about 20-30 minutes for eliminating smell from them. Lastly, the ozone treated rice should be exposed to a flow of air to remove ozone smell. The rice thus treated can be said to fresh and safe for consuming.

Ozone treatment of rice costs about 800-1,000 baht (around $24 – $30) per ton.

Local sources say the government could use the process to treat the rice in the warehouses that is identified as below standard before releasing it for sale.

Thailand government is currently holding around 18 million tons of rice stocks according to the Thai Prime Minister, of the 18 million tons of rice, only 10% are of standard quality, about 70% were below-standard and about 20% were unfit for human consumption.

Ozone gas should be pumped through stockpiled rice to improve its quality and increase its value, a rice mill operator in Phichit says. As the government revealed recently that 90% of the 18 million tonnes kept in state rice stockpiles is sub-standard, he said the ozone fumigation technique could help recover losses from the old rice-pledging scheme. The scheme gave rise to the huge rice stockpiles,…
