Abstract
Peel yellowing and pulp soften are two major causes of quality breakdown in harvested Zaosu pears.The fruit were vacuum permeated with salicylic acid(SA) at 4 mmol/L,3.2×104 Pa and 25 ℃ for 10min in order to evaluate effects of treatment on the color and texture of pears during room storage(25 ℃,RH 85-90%).The results showed that SA treatment increased color value,lightness and hue angle of peel.The treated fruit were 11.3% and 4.7% higher of color value after 14 and 21 days of storage when compared with the control.SA treatment can inhibited the degradation of chlorophyll content and increase of carotenoids in peel.Total chlorophyll content in treated fruit was 48.3% higher than that in control,while carotenoids content was 28.9% lower after 21 days of storage.The chemical delayed the decrease of hardness and fracture and inhibited raise of chewiness of pulp.The hardness and fracture of treated fruit were 14.7% and 25% higher than that in the control after 21 days of storage.It is suggested that SA can inhibit peel color yellowing by delaying of chlorophyll degradation and carotenoids synthesis,and can also maintain crisp texture of pulp by inhibit procedure of ripening of Zaosu pear.
