Scientific Background
Benzoyl peroxide (BPO) is a kind of strong oxidant. BPO is also used as flour brightener. It can completely and rapidly react with yellow carotene which is produced by wheat endosperm, so as to brighten the flour. Besides, it can also accelerate slaking. The reduzate benzoic acid (BA) can restrain the protease and microorganism from growing, avoid protein resolving, and improve the storage tolerance of flour products. However BPO can damage the nutrients such as β-carotene, VB, VA, VE and so on. Too much consumption of BA is not good for health. According to the national food hygienic standard (GB 2760), the maximum usage of benzoyl peroxide in wheat flour is 0.06 g/kg.
Detection method
Rapid Detection
Sensitivity
