| Research Abstract |
Starch synthase I, IIIa (SSIIIa), Pullulanase-deficient rice mutant, that was completely absent in these activity, and the parental Nihonbare were characterized to develop the relationship between the structure of these starches and their rheological properties of starch pastes.
The shape of amyloplast of SSIIIa was unsteady compared to the wild type though, these of PUL and SSI was very similar shape with the wild type. The starch paste of SSIIIa showed the lowest value of the storage modulus and the loss modulus and the relaxation time of H+ was the longest among them. The sensory evaluation score of these cooked mutant rice were lower than wild type cooked rice, so these mutant were suitable as a powder as a functional carbohydrate foods.
