Fake sauce

China probes 'fake seasoning producing hub' near Tianjin

It comes after Beijing News reportedly uncovered the elaborate operation near the city of Tianjin.

The factories were using unapproved ingredients like industrial salt in seasoning including soy sauce and vinegar, the paper said.

The products were labelled with brands including Maggi, Knorr, and Nestle.

China has been rocked by various food scandals in recent years, with tainted milk powder killing six babies in 2008 and making more than 300,000 children ill.
