Introduction

Growth of microorganisms in food material can be


inhabited by adding certain chemical substances.
However the chemical substances should not be
harmful to the human beings.
Such chemical substances which are added to food
materials to prevent their spoilage are known as
chemical preservatives.
In our country, chemical preservative which is
Permitted to use is :
1.POTASSIUM BISULPHITE

Potassium hydrogen sulphite or potassium bisulphate


is a chemical compound with the chemical formula
KHSO3.it is used during the production of alcoholic
beverages as a sterillising agent.
Potassium bisulfite (KHSO3) is formed by reacting
sulfur dioxide (SO2) with potassium carbonate
(K2CO3). Specifically, sulfur dioxide is passed through a
solution of potassium carbonate until all carbon
dioxide is removed, then the solution is concentrated
and allowed to crystallize. This process results in the
formation of potassium bisulfite.
