from those wonderful people that brought you counterfeit baby formula and brake pads:
China Central Television (CCTV), the state television station, first raised public worries over the quality of domestic soy sauce by uncovering a substandard workshop in central China's Hubei Province, where piles of waste human hair were found. The hairs were treated in special containers to distill amino acid, the most common substance contained in soybean sauce.
The plant, describing itself as a bioengineering company, made around 100,000 tons of amino acid daily, in either syrup or powder form, making it easier for delivery, plant workers said. They were then distributed to diluting plants in or near the province, where it was diluted with approximately ten times water, was then made into ready-for-use soy sauce and was bottled or packaged.
In one such plant shown on the CCTV program, more chemical additives were poured into the amino acid syrup and heated and stirred continuously by a worker.
The additives include one whole bag of solid hydroxide to make the sauce taste better, and bottles of hydrochloric acid to balance the acid and alkali content in the mixture in order to make it safer for human consumption. Both additives were for industrial use only, according to their packaging.
