Food produced on mass scales and then distributed to supermarkets needs to have a longer shelf life than fresh foods produced at home which need to be consumed within a shorter time span. Additives are therefore added to such foods to prolong their sell by dates, to prevent the food from going off and giving someone food poisoning. Additives are classified by law into different categories including:
Colours are used to modify the appearance of the food and make it more attractive to the consumer and also in some cases to replace the colour lost during the processing to ensure a consistent colour. The most common colouring used is Plain caramel and it makes up 90% of all colouring used. It is brown/black in colour and is obtained from the heating of sugars. Plain caramel can be found in Coca Cola, beer and chocolate. Beta Carotene is another colouring and is found in plants such as carrots and tomatoes
