Why Food Additives?

What are food additives & why are they used?

Are they used in all processed foods?

No. Additives are only used where necessary and many processed foods do not need them. For example, preservatives are not necessary in canned foods, because canning is itself a method of food preservation. The high temperatures involved in the canning process are sufficient to kill any harmful microorganisms that might be present.
