摘要: 通过差示扫描量热法(DSC)研究糖和盐对葛根淀粉糊化特性的影响,结果表明葡萄糖、果糖和蔗糖均可使葛根淀粉的糊化温度(包括TO,TP和TC)和糊化焓△H升高,不同的糖对提高葛根淀粉糊化温度的顺序依次为蔗糖>葡萄糖>果糖。NaCl的添加也可导致葛根淀粉糊化温度(包括TO,TP和TC)和糊化焓△H升高,其上升的幅度与NaCl的添加量呈正相关性。

Abstract: Thegelatinizationbehaviorofkuzu starchwas investigatedbydifferen tialscanningcalorimetry(DSC).The results showedthatboththegelatin izationtemperature(includingtheonsettemperatureT o ,thepeaktemperatureT p and theconclusiontemperatureT c )andthegelatinizationenthalpyofk uzustarchwereincreasedbytheaddi tionofsugars and NaCl.The increasing effect of diffe rent sugars on gelatinization temperature were in the order of sucrose>g lucose>fructose.TheadditionofNaClhadth eeffectas sugars,andthescaleofth eincreasingwas inthepositivecorr elationwith the adding amount of NaCl.
