This study developed and evaluated a natural composite coating combining mulberry anthocyanin extract from <i>Morus nigra</i> fruits and carboxymethyl chitosan to extend the postharvest life of strawberries. The coating was rationally designed based on complementary functions: carboxymethyl chitosan acts as a semi-permeable barrier reducing water loss and microbial infestation, while mulberry anthocyanin provides antioxidant activity to mitigate oxidative stress-induced senescence. The anthocyanin extract contained cyanidin-3-glucoside (32.9%) and cyanidin-3-rutinoside (29.7%) as major components and exhibited good radCurrent issues in molecular biologyApplication of Mulberry (<i>Morus nigra</i>) Anthocyanin Extract Combined with Carboxymethyl Chitosan for Postharvest Preservation of Strawberry (<i>Fragaria x ananassa</i>).PMC127322762024KCXTD0062024ZDJS1412022GCZX012Huang CSarengaowaHu WZhou BLiu RTang HfalseApplication of Mulberry (<i>Morus nigra</i>) Anthocyanin Extract Combined with Carboxymethyl Chitosan for Postharvest Preservation of Strawberry (<i>Fragaria x ananassa</i>).Strawberries are highly susceptible to postharvest deterioration, including softening, decay, and nutrient loss, which severely limits their shelf life and commercial value.
