Abstract
The moisture adsorption and desorption properties of corn starch, U.S.P., and a directly compressible corn starch were studied. Both systems exhibited Type II adsorption behavior with hysteresis observed in both cases. The B.E.T. method was used to determine monolayer coverage and surface area for both the adsorption and desorption isotherms. It was calculated that the average corn starch granule increased in volume by approximately 9.2% due to swelling in the presence of moisture.Keywords
