Abstract:

In this study, we attempted to elucidate the efect of ethanol extract of Ginko biloba leaves (GBE) at different
concentrations, rich in total flavonoids, on the quality of fresh-cut ‘Red Fuji’ apples as evaluated by measuring total bacterial
count, firmness, color, weight loss, vitamin C content, sensory properties and polyphenol oxidase (PPO) activity. Results
showed that GBE could improve the sensory quality of fresh-cut apples, significantly reduce the weight loss and browning
degree, inhibit vitamin C loss and firmness, and lower microbial levels. In conclusion, GBE at flavonoids concentration
of 0.5 mg/mL showed the best preservation effect.

Key words: ethanol extract of Ginko biloba leaves (GBE), fresh-cut apple, preservation
