It has recently been reported in the media that some soy products have been found to contain possibly carcinogenic substances called 3MCPD and 1,3-DCP (chloropropynols). 3-MCPD and 1,3-DCP can occur during the production of acid-hydrolysed protein. However, these compounds are not detected in Kikkoman Soy Sauces.Kikkoman Soy Sauces are made by a natural brewing method, which does not use the production process of acid-hydrolysed protein.
