Hydroxypropyl methylcellulose (HPMC) film containing bovine bone collagen (BC) and nano-TiO were developed via casting method. The films were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR), and their mechanical properties, barrier properties, thermal stability and surface color were investigated. The results showed that polymer matrices of HPMC and BC had good compatibility. The nano-TiO could be well embedded and dispersed in the matrix of HPMC/BC films, resulting in homogeneous, continuous and compact structure of the composite films. The addition of BC and nano-TiO significantly (p < .05) changed the surface color parameters of the films (p < .05). In addition, the introduction of BC and nano-TiO had a positive effect on the improvement of mechanical properties, barrier properties and thermal stability of the HPMC based films. The results suggest that HPMC based films containing BC and nano-TiO are more suitable for active packaging in the food industry.
通过流延法制备了含有牛骨胶原蛋白（BC）和纳米二氧化钛的羟丙基甲基纤维素（HPMC）薄膜。通过扫描电子显微镜（SEM）和傅里叶变换红外光谱（FTIR）对薄膜进行了表征，并研究了它们的机械性能、阻隔性能、热稳定性和表面颜色。结果表明，HPMC和BC的聚合物基体具有良好的相容性。纳米二氧化钛能够很好地嵌入并分散在HPMC/BC薄膜的基体中，使得复合薄膜具有均匀、连续且致密的结构。BC和纳米二氧化钛的添加显著（p < 0.05）改变了薄膜的表面颜色参数（p < 0.05）。此外，BC和纳米二氧化钛的引入对基于HPMC的薄膜的机械性能、阻隔性能和热稳定性的改善具有积极作用。结果表明，含有BC和纳米二氧化钛的基于HPMC的薄膜更适合用于食品工业中的活性包装。
