As a result, the best heat treatment to estimation is proved to treatment at 135℃ for 1h. Hygroscopicity behavior of heated starch samples (150℃-1h) was observed under different humidity condition. Under 100% humidity, the potato sample absorbed water 35% to dry matter, but the other samples absorbed 25-27%. However, under 52% humidity, all samples absorbed 13-14%. The iodine color reaction of the samples showed little change after heat treatment.}, title = {熱条件の違いによる各種澱粉の水分量と吸湿性の変化}, year = {2010}, yomi = {イトウ, トモミ and ハセガワ, ノブヒロ and ヤマダ, テツヤ} }
