A reminder to the public about an earlier warning by the UK Food Standards Agency about certain batches of Marca Pina Soy Sauce, found to contain unhealthy levels of a toxic substance called 3-monochloropropan-1,2-diol (3-MCPD).
The levels of this chemical in the soy sauce was found to be above the prescribed EU limits. A prevailing opinion about the reason for contamination in the soy sauce due to 3-MCPD, points to the cooking process; when soy sauce is made by the natural fermentation process, it does not get contaminated.
The agency suspects that the presence of certain ingredients like acid hydrolyzed vegetable protein, used to make the soy sauce, may be rendered impure during the hydrolysis process. Those who wish to avoid 3-MCPD are advised to select the fermented soy sauce over the cooked soy sauce.
