Summary
The glass transition temperature of freeze-dried pineapple conditioned by adsorption at various water activities at 25 °C, was determined by differential scanning calorimetry (DSC). The DSC traces showed a clearly visible shift in the base line at the glass transition temperature. Also, no ice formation was observed until the water activity was equal to 0.75. The glass transition curve showed that the glass transition temperature decreased with increasing moisture content.
