| 摘 要： | 以原淀粉为原料用湿法工艺制备的辛烯基琥珀酸淀粉酯，糊的粘度较高，采用洳淀粉酶进行水解得到低粘度的酶解产物，类似于纯胶的变性淀粉产品。本文采用X射线衍射、红外光谱、紫外-可见光谱、HPLC等方法，测定研究辛烯基琥珀酸淀粉酯酶解产物（OSA-SH）的结构、组成、DE值、粘度、表面张力、乳化性参数等理化特性。结果表明，试验的OSA-SH的DE值为3．06，无定形结构，分子中含有C=C、COOR官能团，具有较好的水溶性、高浓低粘性、表面活性和乳化性。

| Abstract: | Octenyl succinic anhydride starch hydrolysate（OSA-SH） was obtained by hydrolyzing octenyl succinic anhydride starch （OSA-S） with a-starch enzyme. The structure and composition were investigated by means of X-ray diffraction, Fourier transforms infrared （FT-IR） spectroscopy, UV-Visible spectroscopy, HPLC, etc. And its physico-chemical properties were determined by measuring DE value, viscosity, surface tension, emulsifying properties and other indicators. Results showed that the DE value of OSA-SH was 3.06. the product possessed amorphous structure containing C=C, COOR groups and OSA-SH, which had some good properties such as water solubility, high concentration and low stickiness, surface activity and emulsifying properties. |
