                 摘要:为了实现香芹酚(CAR)的缓释,减缓食品的氧化变质进程,以明胶(GEL)和聚乙烯醇(PVA)为基
                 材,CAR 为抗氧化剂,采用静电纺丝法制备了 CAR/GEL/PVA 纤维膜。通过 SEM、FTIR、XRD 对纤维膜进行
                 了表征,测定了纤维膜的抗氧化活性、缓释性能和橄榄油的过氧化值,并考察了 CAR 添加量(以纺丝溶液中
                 GEL 的质量为基准)对纤维膜结构和性能的影响。结果表明,随着 CAR 添加量的增加,纺丝溶液的黏度增加,
                 电导率下降,制备的纤维膜形貌由直径较小且分布均匀转变为直径较大且分布不均匀,从而影响纤维膜的力学
                 性能、抗氧化性能和缓释效果。Ritger-peppas 和 Weibull 模型能较好地拟合缓释过程,其相关系数接近于 1,释
                 放规律遵循 Fickian 扩散机制,且当 CAR 添加量为 5%时,纤维膜的缓释效果最佳。高 CAR 添加量的
                 CAR/GEL/PVA 纤维膜能在油脂类食物中缓慢释放,具有较强的抗氧化活性。在 48 h 时,CAR 添加量为 20%的
                 纤维膜的 2,2-联苯基-1-苦基肼基自由基清除率为 82.4%,比未添加 CAR 的纤维膜提升 50.4%,可以有效降低
                 橄榄油的过氧化值。

                 Abstract:  In  order to achieve the sustained-release of  carvacrol  (CAR) and slow  down the  oxidative
                 deterioration  process in  food, CAR/GEL/PVA fibrous membranes  were prepared from gelatin (GEL),
                 polyvinyl alcohol (PVA) and CAR via electrospinning, and characterized by SEM, FTIR and XRD. The
                 antioxidant activity, slow-release performance and  peroxide value of olive oil were analyzed, while  the
                 effect  of CAR addition amount  (based  on the mass of  GEL in spinning  solution)  on the structure and
                 properties of the fibrous membranes was further investigated. The results showed that with the increase of
                 CAR addition amount, the  viscosity  of the spinning solution increased and the electrical conductivity
                 decreased,  while the morphology  of  the  prepared fibrous membrane changed from a  smaller size with
                 uniform distribution to a larger  one  with uneven distribution, thus affecting the mechanical  properties,
                 antioxidant activities and slow-release performance of the fibrous membranes. Ritger-peppas and Weibull
                 models could fit the slow-release process well with a correlation coefficient close to 1, while the release
                 followed  Fickian diffusion  mechanism. When  5% CAR was added, CAR/GEL/PVA fibrous membrane
