Unsafe ingredient in some flours

BEIJING - Recent investigations have found that some bleaching agents widely used in flour production contain as much as 30 percent pulverized lime, a substance that has been linked to health problems.

The result was reported on Wednesday in the Legal Weekend, a publication under the official Legal Daily.

Local insiders, who were worried the material would cause serious harm to public health, reported that pulverized lime is added to the bleaching agent produced by the Yuzhong Food Additive Company in Rugao in East China's Jiangsu province, the report said.
