| Popis: |
The glass transition temperatures for dilute and concentrated fructose-water solutions have been determined by differential scanning calorimetry. The supplemented phase diagram is presented, and from this, the glass transition temperature (T′ g and concentration (C′ g of the maximally freeze-concentrated glass have been determined and found to differ significantly for the latter and slightly for the former, from recently published values. Reasons for this discrepancy are discussed. Annealing vitrified fructose-water glasses above their T g allows the fructose concentration in the amorphous phase to approach C ′ g as a result of ice formation. |
