Opinion | Video: Chinese restaurants found to serve poisonous fake shark fin soup

Think twice before you order your favourite shark fin soup next time - chances are you may be paying for an expensive bowl of mung bean starch gel and gelatine.

A mixture of mung bean starch, gelatine, sodium and other chemicals, the fake fin dish served in expensive restaurants and wedding feasts has become a popular choice among customers, especially those eager to impress guests with a "high-end" dish, said the report.

In a Zhejiang restaurant named Xanadu, a fake bowl of shark fin was sold for 150 yuan (HK$186), while the ingredients cost only 5 yuan, said the report.

CCTV estimated that up to 40 per cent of the shark fins consumed in mainland Chinese restaurants could be fake. Experts warn that chemicals and additives used to make fake fins are poisonous and could damage the lung and other organs.

The shocking revelation has sparked heated discussions on China’s micro-blogging service Sina Weibo. “It’s the corrupt officials who eat shark fins, right?” said a blogger. “It’s a fair world after all.”
