摘  要:
用差示扫描量热法(DSC技术)对高交联非糊化玉米淀粉和高交联非糊化木薯淀粉,在水分散体系中随温度的升高而发生的物态变化进行了研究,结果表明三氯氧磷高交联变性淀粉,尽管已经失去了糊化的性质而保持颗粒状态,但在相应的原淀粉糊化温度范围内,仍然发生了由多晶态向非晶态的相转变。

摘  要:
The properties of physical state of high cross-linked corn and cassava starch were studied by using differential scanning calorimetry (DSC).The results stated that high cross-linked starch kept in granule state,meanwhile lost gelatinization properties.The temperaure range of phase transition from polycrystalline granule to non-crystalline granule accorded well with the temperatue range of native starch gelatinization.
