연구재불동적염산농도、온도、정분용량화반응시간조건하，통과단인소실험화정교실험취득최가공예조건。이용염산수해홍서정분제비미공정분，통과흡유솔고찰료미공정분흡부성능。염산농도위1．5％、온도위45℃、정분용량위20 g、반응시간위8h시，제비홍서미공정분적흡부성능최가。
Sweet potatoes micro-porous starches were prepared using hydrochloric acid hydrolysis methods, and the change law of the sweet potatoes’absorption property under different conditions was studied, such as different dose of hydrochloric acid concentration, temperature, concentration of sweet potatoes and response time.The best technological conditions with Single Factor Experiment and Orthogonal Experiment were studied.It showed that the sweet potatoes’ absorption property was the best only when the use level of hydrochloric acid concentration was 1.5%, the tempretrue was 45 ℃, the concentration of sweet potatoes was 20 g, and the response time was 8 h.
