中文摘要:
      利用Fe3+和单宁酸(TA)制备金属-多酚网络(MPN),并用于纤维素微纤丝(CMF)的功能化改性,以制备CMF-MPN复合物,探讨CMF与MPN制备条件对CMF-MPN复合物抗氧化性和稳定性等的影响。结果表明,MPN可赋予CMF抗氧化性,当TA与Fe3+质量比为4∶1、pH值为3制备的MPN添加量为2%(相对于绝干CMF质量)时,所得CMF-MPN复合物的DPPH清除率达97.0%;热重分析结果表明,CMF-MPN复合物残余质量相对于CMF提高了8.13%,但最大热降解温度略有下降;傅里叶变换红外光谱分析结果表明,CMF与MPN间的吸附为物理吸附;以CMF为载体可以提高MPN结构的稳定性,放置60天后仍能保持初始抗氧化性的80%左右,具有缓慢持续释放抗氧化因子的性能,这为开发绿色食品保鲜包装材料提供了新思路。
Abstract:
      Metal-polyphenol network (MPN) was prepared by Fe3+ and tannic acid (TA), which was further used for functional modification of cellulose microfibrils (CMF), to prepare CMF-MPN complex. The effects of preparation conditions of CMF and MPN on the antioxidant property and stability of the CMF-MPN complex were investigated. The results showed that MPN endowed CMF with antioxidant property, and the DPPH clearance rate of the obtained CMF-MPN complex reached to 97.0% at MPN (prepared at TA∶Fe3+=4∶1 and pH value of 3) additive amount of 2%. The residual mass of CMF-MPN complex increased by 8.13% compared with CMF but the maximum pyrolysis temperature decreased slightly according to the thermogravimetric analysis (TGA). Fourier transform infrared spectroscopy (FT-IR) analysis suggested the physical adsorption between CMF and MPN. Moreover, the application of CMF as a carrier improved the stability of the MPN structure, maintaining 80% of the initial antioxidant property after 60 days, showing the performance of releasing antioxidant factors continuously and slowly. This work provided a new idea for the development of green food preservation packaging materials.
