Theory
Food materials undergo natural changes due totemperature, time and enzymatic action and becomeunfit for consumption. These changes may be checkedby adding small amounts of potassium bisulphite. Theeffectiveness of KHSO

as preservative depends uponits concentration under different conditions which maybe determined experimentally.
Procedure:
1.
Take fresh fruits, wash them thoroughly withwater and peel off their outer cover.2.
Grind it to a paste in the mortar with a pestle.3.
Mix with sugar and colouring matter.4.
The material so obtained is fruit jam. It may beused to study the effect of concentration ofsugar and KHSO
