Food Additives
Functions of Food Additives
- preserving
- increasing shelf-life or inhibiting the growth of pathogens
- adding coloring and flavoring to food
ADDED to foods in precise amounts during processing.

Food Additives are substances added to food to improve its: ___________, ______________, ___________, _____________
- storage properties
- appearance
- flavor
- nutritional value
Food additives that came from plants and animals
Natural Additives
Other additives that use various chemicals
Artificial Additives
4 Common Types of Additives
- preservatives
- nutrient
- coloring
- flavoring
Type of additives that is naturally found (e.g., beetroot juice)
Natural Additives
A natural additive that is used as a COLOURING AGENT (E162)
Beetroot Juice
Type of additives that is a SYNTHETIC COPY of substances found naturally (e.g., benzoic acid)
Manmade Versions
A manmade version additive that is used as a preservative (carbonated drinks content) - E210
Benzoic Acid
A type of additive that is produces SYNTHETICALLY and NOT found naturally (e.g., nisin)
Artificial Additives
An artificial additive that is used as a preservative in some DAIRY products and in semolina and tapioca puddings - E234

3 TYPES OF FOOD ADDITIVES
- natural
- nature identical
- artificial
Substances we add to food to make them taste better, last longer, look nicer, etc.
Food Additives
Substances found naturally, such as beetroot juice, which we use to color foodstuffs.
Natural Additives
Synthesized copies of substances that exist in nature, such as ethyl acetate.
Nature Identical Additives
Synthesized substances that do not exist in nature, such as vanillin or ethyl maltol.
Artificial Additives
Manmade additives may prove more efficient at preserving, and some natural colors fade in some products. (t or f)

Classification of additives that PREVENT the growth of micro-organisms and EXTEND the shelf-life of products
e.g., nitrite and nitrate (E249 to E252) used during curing
PRESERVATIVES
Preservatives used during the curing process (bacon, ham, corned beef)
nitrite and nitrate
Classification of food additives known to prevent food containing fat or oil from oing rancid due to oxidation. Prevent browning of cut fruit, veggies and fruit juices. (e.g., vit C)
