摘要

研究了辛烯基丁二酸酐改性木薯淀粉(OCS)-单甘油酯配合物的结构、性能及其在皮克林乳液中的应用。络合指数、x射线衍射和傅里叶变换红外光谱结果表明，OCS与单甘油三酯形成v型络合物，单月桂酸甘油（GML）比单棕榈酸甘油（GMP）和单硬脂酸甘油（GMS）形成更多的络合物。差示扫描量热分析结果表明，形成的v型配合物包括I型和II型配合物。颗粒形态分析表明，OCS-单甘油三酯复合物比OCS具有更明显的聚集性。OCS- gmp和OCS- gms复合物的接触角比OCS和OCS- gml复合物更接近90°，其顺序为：OCS- gms（62.27°）= OCS- gmp（62.27°）>；OCS-GML（56.79°）>；口服避孕药(23.73°)。与OCS乳液相比，OCS-单甘油酯乳液的平均液滴尺寸更小，储存模量和损失模量更高，乳化效果更好。OCS-GMS乳状液表现出最好的贮藏稳定性和冻融稳定性。本研究表明，ocs -单甘油酯配合物可作为皮克林乳剂的稳定剂。

Preparation and characterization of octenyl succinate cassava starch-monoglyceride complexes and their application in Pickering emulsions

The aim of this study was to investigate the structure and properties of octenyl succinic anhydride-modified cassava starch (OCS)-monoglyceride complexes and their application in the Pickering emulsion. Results from the complexing index, X-ray diffraction, and Fourier transform infrared spectroscopy showed that OCS formed V-type complexes with monoglyceride, and glycerol monolaurate (GML) formed more complexes than glycerol monopalmitate (GMP) and glycerol monostearate (GMS). Differential scanning calorimetry results indicated that the formed V-type complexes included type I and type II complexes. Granule morphology analysis indicated that OCS-monoglyceride complexes had more pronounced aggregation than OCS. The contact angles of OCS-GMP and OCS-GMS complexes were closer to 90° than OCS and OCS-GML complex, with the order of OCS-GMS (62.27°) = OCS-GMP (62.27°) > OCS-GML (56.79°) > OCS (23.73°). OCS-monoglyceride emulsions displayed lower average droplet size, enhanced storage modulus and loss modulus, and better emulsifying effect than OCS emulsion. OCS-GMS emulsion showed the best storage stability and freeze-thaw stability. This study demonstrated that the OCS-monoglyceride complexes would be employed as a potential stabilizer in Pickering emulsions.

期刊介绍： The International Journal of Biological Macromolecules is a well-established international journal dedicated to research on the chemical and biological aspects of natural macromolecules. Focusing on proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins, biological poly-acids, and nucleic acids, the journal presents the latest findings in molecular structure, properties, biological activities, interactions, modifications, and functional properties. Papers must offer new and novel insights, encompassing related model systems, structural conformational studies, theoretical developments, and analytical techniques. Each paper is required to primarily focus on at least one named biological macromolecule, reflected in the title, abstract, and text.
