Abstract: Fish collagen coating and collagen/green tea extract (GTE) coating were prepared with silver carp skin collagen and GTE, which were used to investigate the preservation effects on cherry tomatoes. The rate of water-loss and decay, titratable acid, browning, activity of polyphenol oxidase and polyphenol were measured.Results showed that edible film coating treatment could decrease the rate of water-loss and decay, prevent browning and the activity of polyphenol oxidase, lower the loss of titratable acid and polyphenol. Thus, the collagen/GTE coating had good preservation effect on cherry tomatoes.
