| Outline of Final Research Achievements |
Increasing pH of starch pastes or starch gels by adding sodium carbonate or calcium hydroxide caused higher starch gelatinization temperature and gelatinization temperature, i.e. hindering starch gelatinization. However, when the samples were heated at higher temperature than gelatinization temperature, the collapse of starch granules were promoted, then a lot of amylose and amylopectin leached out from starch granules. Therefore, the viscosity of starch pastes and the gel strength of starch gels increased. Moreover, the retrogradation of both starch pastes and starch gels were inhibited.
