The results show that the structure of KGM segment can be optimized by molecular simulation method and the most stable conformation can be found, indicating the hydrogen bond is the main factor influencing the conformation and property of KGM.展开更多
Konjac black tea(sugar-free) and konjac glucomannan(KGM) solution were studied by using rheometer,refractometer etc.The relationship between their rheological properties and temperature or concentration was discussed ...Konjac black tea(sugar-free) and konjac glucomannan(KGM) solution were studied by using rheometer,refractometer etc.The relationship between their rheological properties and temperature or concentration was discussed in detail.The results showed that viscosity was significantly affected by temperature and concentration;and pH stability of Konjac-tea was related to the molecular property of KGM.展开更多
