| 摘 要： | 将非晶颗粒态淀粉和原淀粉在阴离子、阳离子、醋酸酯及羟丙基醚化剂条件下进行淀粉改性反应,取代度随醚化剂量的改变而改变,但由于整个颗粒处于非晶状态,导致非晶淀粉取代度和原淀粉相比有不同程度的提高,对羧甲基化,取代度平均提高9.15%,最高达10.72%,对阳离子化来说,取代度平均提高9.65%,最高达13.18%,对醋酸酯化,取代度平均提高47.49%,最高达64.82%,对羟丙基化,取代度平均提高22.78%,最高达27.48%.

| Abstract: | Non-crysallized and native potato starches were carboxymethylied,cationizatied,hyxoypropylied,acetylied respectively,DS changed with amount of etherified reagent.Because of whole granules being in non-crystallized state,DS of non-crystallized granule stated starches was higher than that of native starches:when potato starch was carboxymethylied,DS of starches increased 9.15% average,10.72 heighest.While cationizatied,DS of starches increased(9.65%) arerage,13.18 heighest.To be hyxoypropylied and acetylied,DS of starches increased 22.78% average,27.48% heighest and 47.79% average,64.28% heighesr respectively. |
