Analgesics are drugs that reduce or totally abolish pain without causing disturbances of
nervous system. There are two types of analgesics

i. Narcotic analgesics                      E.g.: Morphine
ii. Non-narcotic analgesics              E.g.: Aspirin, ibuprofen

The chemical substances are added to the food to enhance the appeal and to preserve
(To store) the food for a long time. These are known as food preservatives.

Analgesis abolish or resduce pain without causing impairment of conciousness,mental confusion,incoordination or paralysis of nervous system.
EXAMPLE=Aspirin and Paracetamol
Food preservatives are the chemical substances that stop the growth or delay the growth of bacteria,spoilage and its discolouration.
Ex=SODIUM BENZOITE AND SULPHUR DIOXIDE

An analgesic or painkiller is any member of the group of drugs used to achieveanalgesia, relief from pain. Analgesic drugs act in various ways on the peripheral and central nervous systems. They are distinct from anesthetics, which reversibly eliminate sensation.
example – aspirin and paracetamol 

preservative is a substance or a chemical that is added to products such as food, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes.
example – vinegar , sulpher dioxide .

Analgesis is defined as the drugs that reduce or abolish pain without causing impairment of conciousness,mental confusion,incoordinationor paralysis or some other disturbances of nervous system.
analgesis are of two types:-
(i)narcotic or addictive analgesis-Morphine and many of its homologues are narcotic or habit forming analgesis.           
(ii)Non-narcotic or non-addictive analgesis- aspirin and paracetamol belong to the class of non narcotic analgesis.
 
Food Preservatives are defined as the chemical substances that stop the growth of bacteria and prevent the spoilage of food and prevent it discolouration.
Ex-:sulphur dioxide and sodium benzoites etc,
