Differential Scanning Calorimetry Study of Phase Transitions Affecting the Quality of Dehydrated Materials

摘要: Differential scanning calorimetry was used to determine the phase transitions of dried and rehumidified amorphous lactose, sucrose, a mixture sucrose Amioca. Glass-transition, crystallization, melting temperatures decreased with increasing moisture content. The time crystallization lactose held isothermally above glass-transition temperature as increased. Isothermal function difference between holding independently Amorphous biological materials are metastable showing temperature, content, time-dependent that affect their drying behavior, stickiness, storage stability, quality.
