Methods of and compositions for producing and using plant-based materials are provided. The methods include using biopolymers or their synthetic equivalents combined with a stable source of reactive oxygen species that when applied to or combined with a separate source of oxido-reducing enzyme or catalyst will cause the formation of an activated biopolymer with increased protein binding affinity and microbial control activities.本發明提供使用和製備植物性材料的方法和組合物。該方法包括使用生物性聚合物或其合成等價物,其係結合一穩定的活性氧化物來源。該活性氧化物來源係導入或結合於一獨立之氧化還原酵素或觸媒來源,以促使一經活化而具有增強之蛋白質鍵結親和力和控制微生物活性的生物性聚合物生成。
