Outline of Final Research Achievements |
The PDI activity was different between super strong flour, strong flour and medium flour, and strong flour showed high activity. In addition, the PDI activity in the wheat flour reached a peak at 20 to 25 days after anthesis at the late stage of wheat grain ripening and then showed a tendency to decrease. It was inferred that the PDI expressed at this time remained in the wheat flour and was involved in S - S bond formation in the dough. Analysis of the S - S bond formation state in the wheat dough suggested that intermolecular S - S bonds were formed in the 30 - 40 kDa protein and the molecular weight was increased.
