Hygroscopic material, when it comes into contact with atmospheric air, desorps or absorps the moisture from the surroundings until it reaches equilibrium. In the present study, groundnut and chillies were dried in a controlled air supply (at a particular temperature and relative humidity). The equilibrium moisture content (e.m.c.) and relative humidity (r.h.) relationships were studied at different temperatures. Values of constants c and n of Henderson's equation were computed and desorption isotherms were drawn for groundnut components and chillies. It was observed that e.m.c. depends upon type of material, the temperature and r.h. of the air.
