Abstract

A hygrometer method was used to determine the water vapor adsorption isotherms of guava, mango and pineapple. The method proved that combining rapid water activity measurement with sample rehydration at low temperature may be used to determine the isotherms of the fruits at 25 and 50 degrees celsius. The isotherms of the three fruits were found to be unaffected by temperature. Drying process was observed to increase the sorption capacity of freeze-dried pineapple than the vacuum dried process.
