杨木单板/桑葚花青素高精度pH智能指示标签的制备及在猪肉新鲜度监测中的应用
Fabrication of poplar wood veneer/mulberry anthocyanins based high-accuracy pH-smart label and its application in pork freshness monitoring
随着消费者对食品安全重视程度的提高,能够迅速监测食物新鲜度的智能膜材料高速发展。pH智能指示膜是可以根据周围环境pH值的改变而诱导自身颜色发生变化从而进行感知、响应的功能化材料。目前,智能膜领域的发展潜力巨大,是保障食品安全简便且先进的手段。但其存在制备过程繁琐、原料成本高、能耗大、遮光性差等问题。本研究采用杨木单板代替多糖、蛋白质等聚合物作为智能膜基材,通过碱性 H2O2 处理同时实现了对木材的漂白和羧基化改性,进而将羧基化单板吸附桑葚花青素,…查看全部>>
The pH-smart films are functional materials that can change their own color depending on the different pH values of the surrounding environment.Currently,there is a huge potential for development in the field of smart membranes as an easy and advanced way to protect food safety.However,it suffers from problems of complicated production,high cost,high energy consumption and low light-barrier.In this study,poplar veneer was used as an alternative to the film m…查看全部>>
