But the chemistry is a little bit different when it comes to what's probably the world's most commonly used preservative: Sodium Benzoate.

但是当谈到世界上常用的防腐剂时，它的化学成分有点不同：苯甲酸钠。

Sodium benzoate, for example, has been found to react with ascorbic acid — aka Vitamin C — to produce benzene, a hydrocarbon that's known to cause cancer.

例如，研究发现苯甲酸钠与抗坏血酸——也就是维生素 C——反应产生苯，而苯是知会导致癌症的碳氢化合物。
