| 摘 要： | 采用差示扫描量热法(DSC)分析,研究不同相对湿度(RH)条件下,酪蛋白酸钠(NaCas)膜的热特性以及谷氨酰胺转移酶(TGase)改性对热特性的影响。对于NaCas膜,无论是对照膜还是TGase改性膜,蛋白膜的热稳定性随着RH的增高而下降。TGase改性改变了NaCas膜吸热峰出现的位置与数量。在同一RH时,TGase改性膜更易失去水分。TGase改性使NaCas膜的耐热特性发生了明显改变,可能是TGase作用改变了NaCas的不同组分的耐热特性所致。

| Abstract: | Thermal properties of sodium caseinate(NaCas)films at different relative humidity(RH)and effect of transglutaminase(TGase)treatment on them were studied by DSC analysis.For NaCas films-control films and TGase-treated films,thermal stability was decreased with RH increasing.TGase treatment changed the location and quantity of endothermic peak of NaCas films.At the same RH,TGase-treated films were easier to lose moisture as compared with control films.TGase treatment significantly changed the heat-resistant q... |
