4. A Glass Formation Ability and a Glass State Stability of Sugars in Aqueous Alkali Metal Chloride-Sugar Solutions(the 47th Annual Meeting)

Abstract

The low-temperature thermal behaviour of aqueous alkali metal chloride-sugar solutions was investigated by differential scanning calorimetry (DSC). Glucose, galactose, mannose and fructose as a monosaccharide, trehalose as a disaccharide, raffinose as a trisaccharide, sodium chloride and potassium chloride as an alkali metal chloride were used. From the results, NaCl has a higher glass formation ability than KC1, glucose and galactose have a slight higher glass formation ability than mannose and fructose. The four monosaccharides have an almost same glass state stability. Trehalose and raffinose have the almost same glass formation ability and glass state stability as monosaccharides per a sugar ring.
