Evaluate the benefits of food additives for consumers.

Additives extend shelf life, reduce food waste and help prevent food poisoning. Additives also make possible the lower-sugar, lower-fat and convenience products that many consumers want.

Why are some consumers concerned about food additives?

Some additives have been linked to hyperactivity, allergic reactions or intolerance in sensitive people. Additives can also make highly processed foods more appealing and disguise poor-quality ingredients.

What does an E number show?

An E number shows that an additive has been evaluated and approved for use in the EU. The number identifies the additive on an ingredients list.

How are E numbers grouped by function?

E100s are colours, E200s are mainly preservatives and E300s are mainly antioxidants. E400s are thickeners and emulsifiers, E600s are flavour enhancers and E900s include sweeteners.

Sulphite vs Benzoate
Sulphite: a preservative that stops browning in dried fruit and wine and can trigger asthma. Benzoate: a preservative used in soft drinks that can form benzene with vitamin C.
