During the storage period, the incidence of berry decay was gradually increased (Fig. 1). After 60 days storage at 0 °C, the decay rate of control (25.27%) was significantly higher than that of other samples (CGC, 2.29%; chitosan, 3.65%; glucose, 5.27%). At the 5 d shelf life, decay levels of all samples obviously increased. Berry decay in the control was 42.6%, whereas fruits treated with chitosan, glucose, or chitosan–glucose complex showed the values of 7.55%, 9.60% and 4.52%, respectively. Throughout the storage period, the decay rate of fruits coated with chitosan–glucose complex was the lowest.
