| Outline of Final Research Achievements |
We investigated the rheological properties of liquid egg mixed with milk fat cream or rapeseed oil during heating and its heat-induced gel structure and texture. In experiments the omelet was used as a sample, dynamic linear viscoelasticity measurements at 80℃ were highly variable for the milk fat cream mixture and relatively uniform for the rapeseed oil mixture. When liquid egg was heated with milk fat cream or rapeseed oil in an omelet-like form, the resulting gel showed a porous structure by scanning electron microscopy. Texture measurements and sensory evaluation demonstrated that heat-induced gel with milk fat cream exhibits vulnerable properties. These results demonstrated that the addition of milk fat cream or rapeseed oil into liquid egg altered the rheological properties of the liquid egg during heating as well as the heat-induced gel structure, and generated a unique, vulnerable or flexible, texture.
