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.
