AM-GMS, AM-SE, AM-SSL complex were prepared by using B-type microcrystalline, glycerol monostearate (GMS), sodium stearyl lactate (SSL) and sugar esters (SE) as materials. The forming conditions of the complex were as bellow:starch concentration, 5%(w/w);starch/ligand ratio, 20∶1;the materials were completed at 90℃, ageing at 121℃and 90℃, then slowly cooling and precipitated at low temperatures. The structures of the complex were characterized by XRD, DSC, IR, and GPC. The IR data of the three samples were analyzed by PAC. The result showed that: The crystal structures of the three complexes are all V-type microcrystalline. The relative crystallization of the AM-GMS, AM-SE, AM-SSL complex are 70.5%, 51.9%and 60.1%respectively. The stability order is AM-GMS>AM-SSL>AM-SE. The relative molecular mass of the AM-GMS, AM-SE and AM-SSL are 3 044, 3 449 and 3 265 respectively. The ligand content of the AM-GMS, AM-SE,AM-SSL complex are 17.09%, 15.45%and16.39%, respectively.%以B-型微晶淀粉为原料,选择硬脂酰单甘脂(GMS)、硬脂酰乳酸钠(SSL)和硬脂酰蔗糖酯(SE-15)为配体,固定淀粉质量分数为5%,淀粉与配体的质量比为20∶1,原料混合后经90℃溶解,121℃和90℃两个阶段的复合,再经缓慢冷却和低温凝沉制备得到了AM-GMS,AM-SE和AM-SSL 3种复合物,应用X-射线衍射(XRD)、差示扫描量热仪(DSC)、红外光谱仪(IR)和凝胶渗透色谱对样品进行了测试和分析,并应用主成分分析法(PAC)对3种样品的红外光谱数据进行了分析。结果表明:实验研究所得到的3种复合物均为V-型结晶结构,其稳定性大小顺序为AM-GMS>AM-SSL>AM-SE;AM-GMS,AM-SE和AM-SSL 3种复合物的相对结晶度分别为70.5%,51.9%和60.1%;3种复合物的重均分子量分别为3044,3449和3265;3种复合物中配体的含量分别为17.09%,15.45%和16.39%。
