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.La presente invención se refiere a un proceso para preparar una composición antibacterianas que comprende las etapas de: a) combinar cáscara de granada con agua y calentamiento de 80°C a 150°C para desnaturalizar sustancialmente enzimas endógenas a la cáscara de granada； y b) añadir desde 1% hasta menos del10% de peróxido de hidrógeno al producto obtenido de la etapa (a).
