| Research Abstract |
Thermal properties of polysaccharide-water systems and polysaccharide hydrogels derived from various bean plants was investigated. Phase diagrams of plant polysaccharide-water systems, such as various galactomannans and psyllium seed gum, were establishedby differential scanning calorimetry (DSC). Gelation mechanism of various galactomannanpolysaccharides by freezing and thawing was investigated. Furthermore, gelation mechanism of psyllium seed gum with various molecular mass and gel-sol transition was investigated. From these results, it was found that plant polysaccharides have various characteristics
