Ethical Man has discovered a whole range of food additives don’t even get listed on the ingredients.
I’m spending a month as vegan to see how cutting animal products out of my diet will affect my environmental footprint. It is surpisingly difficult to avoid animals; you'd be amazed how many foods contain animal products in some form or other.
There was a huge response when I wrote about my concerns that an amino acid used as an additive in bread is sometimes manufactured from human hair. I was reassured to discover that it is possible to avoid the substance – called L-Cysteine or E920 – because it is listed on the ingredients.
Then last week Britain’s leading organic baker, Andrew Whitely, wrote to me to warn of what he calls of “baking’s big secret” – the use of enzymes.
Andrew describes the use of these enzymes as secret because they do not appear on the label. Industrial bakers use a loophole to classify them as “processing aids”. The problem for a vegan like me – or for that matter for Jews, Muslims and vegetarians – is that some of these enzymes are manufactured from animals, including pigs.
