Anything that comes in a box, tin, bag, carton or bottle has to bear a label listing its contents, and many of us have become experts at reading these labels. But many of the additives and ingredients that once jumped out as fake and unfathomable have quietly disappeared. Does this mean that their contents have improved? In some cases, yes, but there is an alternative explanation. Over the past few years, the food industry has embarked on an operation it dubs “clean label”, with the goal of removing the most glaring industrial ingredients and additives, replacing them with substitutes that sound altogether more benign. Some companies have reformulated their products in a genuine, wholehearted way, replacing ingredients with substitutes that are less problematic. Others, unconvinced that they can pass the cost on to retailers and consumers, have turned to a novel range of cheaper substances that allow them to present a scrubbed and rosy face to the public.

Imagine you are standing in the supermarket. Maybe you usually buy some cured meat for an antipasti. Picking up a salami, even the most guarded shopper might relax when they see rosemary extract on the ingredients list – but rosemary extracts are actually “clean-label” substitutes for the old guard of techie-sounding antioxidants (E300-21), such as butylhydroxyanisole (BHA) and butylhydroxytoluene (BHT). Food manufacturers use them to slow down the rate at which foods go rancid, so extending their shelf life.

Rosemary extracts don’t always have to carry an E number (E392), but the more poetic addition of “extract of rosemary” makes it sound like a lovingly made ingredient – especially if that salami is also labelled as natural or organic. And the extract does have something to do with the herb, usually in its dried form. The herb’s antioxidant chemicals are isolated in an extraction procedure that “deodorises” them, removing any rosemary taste and smell. Extraction is done by using either carbon dioxide or chemical solvents – hexane (derived from the fractional distillation of petroleum), ethanol and acetone. Neutral-tasting rosemary extract is then sold to manufacturers, usually in the form of a brownish powder. Its connection with the freshly cut, green and pungent herb we know and love is fairly remote.

Not sure what to have for dinner? How about a chicken noodle dish? If you noticed that it contained an amino acid such as L-cysteine E910, your enthusiasm might wane, especially if you happen to know that this additive can be derived from animal and human hair. But a range of new-wave yeast extracts is increasingly replacing E910. One supplier markets its wares as “a variety of pre-composed, ready-to-use products that provide the same intensity as our classical process flavours but are labelled as all-natural. Ingredients are available in chicken and beef flavour, with roasted or boiled varieties, as well as white meat and dark roast.” All can be labelled as “yeast extract” – a boon for manufacturers, because yeast extracts have a healthy image as a rich source of B vitamins. Less well known is the fact that yeast extract has a high concentration of the amino acid glutamate, from which monosodium glutamate – better known as MSG, one of the most shunned additives – is derived.

I thought there were 5 major food groups: alcohol, nicotine, sugar, caffeine, and (one more, I forget).
