                 摘要:以酶解处理后的水溶性辛烯基琥珀酸糯玉米淀粉酯(简称 OSS)为原料,三偏磷酸钠为改性剂,制备了
                 改性 OSS 膜,以膜的抗拉强度为响应值,通过单因素和响应面实验优化了 OSS 膜的改性工艺,采用                                31 PNMR
                 和 FTIR 对最优条件下制备的膜进行了表征。结果表明,在反应时间 5.8 h、pH 6.8、三偏磷酸钠用量为 OSS 质
                 量的 18%的最佳工艺条件下,改性 OSS 膜的抗拉强度为 2.19 MPa,比 OSS 膜提高了 69.77%。改性 OSS 膜断面
                 均匀,起始相变温度提高 14.6  ℃,归因于三偏磷酸钠和 OSS 间的氢键键合提高了 OSS 膜的性能。OSS 乳化负
                 载维生素 E 后再经三偏磷酸钠改性可有效提高乳化膜中维生素 E 的高温(60 ℃)贮藏稳定性。

                 Abstract: Modified octenyl succinic anhydride  waxy corn starch  (OSS)  film was  prepared  via  sodium
                 trimetaphosphate  modification of enzyme-hydrolyzed OSS. The modification  process was optimized  by
                 single-factor experiment and response surface methodology with tensile strength of film as response value,
                 and the structure of the modified OSS film obtained under the optimal conditions was characterized by
                 31
                  PNMR and FTIR. The results showed that, under the optimal conditions of reaction time 5.8 h, pH 6.8,
                 trisodium trimetaphosphate 18% of OSS mass, the tensile strength of the modified OSS film was 2.19 MPa,
                 69.77%  higher than that of the  OSS  film. Meanwhile, the modified  OSS  film displayed a  more
                 homogeneous cross section with onset phase transition temperature increased by 14.6  ℃, which could be
                 attributed to the hydrogen bond formed between sodium trimetaphosphate and OSS. Moreover, it was found
                 that trisodium trimetaphosphate modification of OSS loaded with vitamin E could effectively improve the
                 film-forming property of the film and the storage stability of vitamin E in high temperature (60 ℃).
