A ban on the production and use of two food additives in flour processing will take effect on May 1.

The two additives, benzoyl peroxide and calcium peroxide, were banned because "there is no need to use them in flour processing anymore" as the country's processing techniques and wheat planting had improved, the Ministry of Health said in a statement on its website on March 1.

Targeting illegal food additives in China's food safety overhaul last year, authorities have cracked down on 5,305 related cases and confiscated more than 19.8 million yuan ($3.01 million) of illegal gains and goods worth more than 60 million yuan ($9.39 million), the ministry's figures show.
