| Outline of Final Research Achievements |
"Rice" is our staple food and it is an important source of nutrition. Also, it is easy to domestic self-sufficiency in Japan, it is also a food crop with advanced cultivation technology. This research creates new rice by natural mating, not genetically engineered technology, and creates rice and rice starch with a unique structure. Furthermore, the rice starch was separated and the microstructure and rheological properties were measured to show the characteristics of mutant rice. In addition, we evaluated the taste cell response using the developed taste DNA chip. The response of the tasting was different depending on the properties of the polysaccharide solution. Although this result was lower than the human threshold, movement of tasting and response of taste cells could be caught.
