Some soy sauce might have 3-MCPD! The condiment is made by fermentation of soya. Then it is sold as concentrate or ready to use products. However, there is a faster and more economical way of production, the acid hydrolysis of protein. The process is carried out by mixing soya with hydrochloric acid and heating afterwards. This produces flavors and appears similar to naturally fermented version. Then the fat content of veggies reacts with HCl to form the carcinogenic 3-MCPD.
The natural process, fermentation of soya beans never produces 3-MCPD.
The Philippine Food and Drug Administration warned the public against the unlabeled and unregistered soy sauce brands. They might contain 3-MCPD. The substance was found to cause cancer in animal experiments. The same effect is expected to happen to human beings.
To assure public safety, the agency have been testing commercially available soy sauce brands. Here are the partial list of 3-MCPD free brands. Listing courtesy of DOH.
