Abstract:
The effect of postharvest treatments of 2% CaCl2 treatment，0.2% chitosan coating treatment，2% citric acid treatment on peel calcium fractions and browning of ‘Nan Guo’pear were studied during storage，soaking with water as control.The results showed that the total calcium contents of 2% CaCl2，0.2% chitosan coating treatment and 2% citric acid treatment treated fruits were higher than those of control respectively and delayed the decrease of total calcium content；pectin calcium was the main form of calcium in fruit，its content of total calcium accounted for 53.4%-75.1%；treatments with 2% CaCl2 treatment，0.2% chitosan coating treatment and 2% citric acid treatment inhibited the declines in water soluble calcium and pectin calcium，promoted the increase of calcium oxalate.The end of storage，incidence rate of pears treated with 2% CaCl2 treatment was 5.556%；incidence rate of pears treated with 0.2% chitosan coating treatment was 16.667%；incidence rate of pears treated with 2% citric acid treatment was 25.000%，while incidence rate of control fruit was 88.889%.Correlation analysis showed that the content of water soluble calcium，pectin calcium and calcium oxalate were significantly positive correlation with browning,while the content of calcium phosphate was significantly negative correlation with browning.Treatments with 2% CaCl2 treatment，0.2% chitosan coating treatment and 2% citric acid treatment delayed peel browning by inhibiting the transformation of soluble calcium to insoluble calcium，and pears treated with 2% CaCl2 were the best.
