Abstract

In this study, the preparation of novel structures by ultra high pressure (UHP) treatment for aqueous PEG/polysaccharides two-phase system was investigated. For polyethylene glycol (PEG) or dextran (DEX) solutions, the clear solutions were maintained after UHP treatment. On the other hand, when PEG (Mw: 6,000 or 8,000) were mixed with DEX (Mw:60,000-90,000) or pullulan, the solution with light scattering was obtained. After UHP treatment, aqueous two-phase separation having light scattering in lower phase was obtained for all cases, suggesting that apparent molecular weight was increased by the formation of PEG/ polysaccharides complex. DLS measurement of them before/after UHP treatment was carried out. The particle size was increased by UHP treatment, then decreased by heat treatment at 50 degrees, indicating the formation of novel hydrogen bonding structures.
