Food Additives
Natural additives are substances found naturally in
a foodstuff and are extracted from this food to be
used in another, for example beetroot juice with its
bright purple colour can be used to colour other
foods such as sweets.
Nature identical additives are manmade copies of
substances that occur naturally. For example,
benzoic acid is a substance that is found in nature
and is made synthetically and used as a
Artificial additives are not naturally present in foods
and are made synthetically. An example is
azodicarbonamide, a flour improver that is used to
help bread dough hold together.…read more

and so are only used in tiny
This makes them suitable for use
in products such as diet drinks,
which are very low in energy.
Bulk sweeteners (such as sorbitol
and sucralose) have a similar
sweetness to sugar so are used in
similar amounts.…read more
