Additives (2)
This label lists 1 emulsifier and 1 flavour enhancer.
E471
Mono- and diglycerides of fatty acids
Emulsifier
What it is. Fat derived emulsifiers, closely related to ordinary dietary fats.
Why it is used. One of the most used additives in food: bread, margarine, ice cream, cakes and sauces.
What the evidence says. The body handles these much as it handles other fats, and EFSA's re-evaluation raised no safety concern at the levels used. They sit in the same broad emulsifier and gut microbiome research question as the others, which remains unsettled.
Permitted without a numerical limit. The fat source is not always stated, which matters for some diets rather than for safety.
Assessed against EFSA. Full entry for E471
E621
Monosodium glutamate
Flavour enhancer
What it is. The sodium salt of glutamate, an amino acid found naturally in tomatoes, cheese and mushrooms.
Why it is used. Boosts savoury, umami flavour in stocks, crisps, ready meals and sauces.
What the evidence says. The old idea of MSG causing headaches and flushing, once called Chinese restaurant syndrome, has not held up in controlled trials. Regulators worldwide treat it as safe at normal intake. A genuinely useful example of a feared additive that the evidence exonerates.
Permitted and classed as safe. Adds to total sodium, so it counts towards salt if a product uses a lot.
Assessed against EFSA, JECFA, US FDA. Full entry for E621
