作品介绍：

     FreshTag是一种基于生物膜和PH敏感技术合成的可持续食品包装。FreshTag的包装技术可以让包装颜色随食品新鲜度的下降而改变。这种技术可以鉴别出包装食品是否安全，解决了食物的浪费问题，同时减少消费者对虚假印刷的生产日期的依赖。

     FreshTag is developing a sustainable food packaging that is biofilm-based and pH-sensitive. FreshTag's packaging technology dynamically changes colour as food freshness decreases, signposting when the packed food is safe or unsafe for consumption, thus eliminating food wast and reducing consumer dependence on unreliable used-by dates.
