| Outline of Final Research Achievements |
In enteral nutrition with gastrostomy (PEG), semi-solidified nutrition with coagulant added to enteral nutrients is used to reduce complications such as diarrhea, gastroesophageal reflux, aspiration pneumonitis.
In this study, to investigate the factors such as drastically viscosity increase and syneresis at the preparation of semi-solidified nutrient. The chemical reaction between enteral nutrient and coagulant was stopped by dehydration. After dehydration, hydration was performed to dehydrated semi-solidified nutrient, change in properties and syneresis were investigated.
As a result, adding an equal amount of water to after dehydrating semi-solidified nutrient, the viscosity did not recover to the before dehydration. Although the nutrient and coagulant chemically react with each other to form a three-dimensional mesh network structure, water impossible return to the inside of original mesh. In conclusion, "water separation" occurred by coexisting semi-solid region and water.
