Food additives are chemicals that keep foods fresh or enhance their colour, flavour or texture.
Food additives are chemicals added to foods to keep them fresh or to enhance their colour, flavour or texture. They may include food colourings (such as tartrazine or cochineal), flavour enhancers (such as MSG) or a range of preservatives.

Most food additives are listed on the product label, along with other ingredients, in a descending order by weight. Sometimes, the additive is spelt out in full. At other times, it is represented by a code number.
The different types of food additive and their uses include:

Anti-caking agents – stop ingredients from becoming lumpy.
Antioxidants – prevent foods from oxidising, or going rancid.
Artificial sweeteners – increase the sweetness.
Emulsifiers – stop fats from clotting together.
Food acids – maintain the right acid level.
Colours – enhance or add colour.
Humectants – keep foods moist.
Flavours – add flavour.
Flavour enhancers – increase the power of a flavour.
Foaming agents – maintain uniform aeration of gases in foods.
Mineral salts – enhance texture and flavour.
Preservatives – stop microbes from multiplying and spoiling the food.
Thickeners and vegetable gums – enhance texture and consistency.
Stabilisers and firming agents – maintain even food dispersion.
Flour treatment – improves baking quality.
Glazing agent – improves appearance and can protect food.
Gelling agents – alter the texture of foods through gel formation.
Propellants – help propel food from a container.
Raising agents – increase the volume of food through the use of gases.
Bulking agents – increase the volume of food without major changes to its available energy.
