Resumen
El camote morado es un tubérculo rico en antocianinas, compuestos que cuentan con propiedades antioxidantes y una notable sensibilidad a cambios de pH, lo que permite su uso como un indicador visual de frescura para empaques alimenticios (películas). Promover el uso del camote como fuente de compuestos bioactivos en el desarrollo de películas permite no solo sustituir plásticos convencionales, sino también proporciona información visual del estado de conservación del alimento. Con esta innovación se puede reducir el desperdicio de alimentos, aprovechar cultivos nativos para otras aplicaciones y al desarrollo de empaques sostenibles.
Palabras clave: Películas; camote; antocianinas; empaque inteligente; bioempaque.
Abstract
Purple sweet potato is a tuber rich in anthocyanins; pigments with antioxidant properties and a notable sensitivity to pH changes, which enables their use as visual freshness indicators in food packaging (films). Promoting the use of sweet potato as a bioactive source in the development of such films could not only replace conventional plastics but also provide visual cues regarding the preservation state of a food. This innovation has the potential to reduce food waste, diversify applications of native crops, and support the development of sustainable packaging.
Keywords: films; sweet potato; anthocyanins; intelligent packaging; biopackaging.
