El uso de la colorimetría triestímulo permitió evaluar la estabilidad del color de los extractos enriquecidos en antocianinas (AREs) de cuatro frutas tropicales Colombianas: motilón, coral, uva de árbol y mora pequeña, a diferentes valores de pH y durante un periodo de almacenamiento de un mes. Se encontró que el color de todos los extractos variaba con el pH y fue estable a pH ácido. El extracto más estable fue de la uva de árbol (M. cauliflora) debido a las menores variaciones en el croma.
