Octenyl succinic anhydride (OSA) has been widely reported for modification of starches and bears an amphiphilic character and is permitted for food applications. The present study was conducted to impart an amphiphilic character to tamarind seed xyloglucan (TSX) by its conjugation to OSA with an objective to impart amphiphilicity. The conjugate gains an amphiphilic character when hydrophilic groups of TSX bonded to hydrophobic octenyl groups. The TSX-OSA conjugate was characterized using Fourier Transform Infrared Spectroscopy (FTIR), Nuclear Magnetic Resonance (NMR), Thermal Gravimetric Analysis (TGA), and Scanning Electron Microscope (SEM). The FTIR, NMR results confirmed the conjugation of TSX-OSA. The TGA analysis revealed lower thermal stability of TSX-OSA conjugate due to introduction of hydrophobic OSA group thereby further confirming conjugation. The SEM micrograph shows that the conjugate possess a smoother surface in comparison to TSX. Hence, the conjugate can be envisaged as an improved material thereby expanding the applications of TSX in terms of its use in designing new products for drug delivery as well as for food applications.

辛烯基琥珀酸酐（OSA）已被广泛报道用于淀粉的改性，具有两亲性，可用于食品。进行本研究是通过将罗望子种子木葡聚糖（TSX）与OSA结合来赋予两亲性，目的是赋予两亲性。当TSX的亲水基团与疏水性辛烯基键合时，共轭物具有两亲性。使用傅立叶变换红外光谱（FTIR），核磁共振（NMR），热重分析（TGA）和扫描电子显微镜（SEM）对TSX-OSA共轭物进行表征。FTIR，NMR结果证实了TSX-OSA的缀合。TGA分析显示由于引入了疏水性OSA基团，TSX-OSA缀合物的热稳定性较低，从而进一步证实了缀合。SEM显微照片显示，与TSX相比，缀合物具有更光滑的表面。因此，可以将缀合物设想为改进的材料，从而就其在设计用于药物递送以及食品应用的新产品方面的用途扩展TSX的应用。
