- Abstract:
- Taking chitosan (CTS) and carboxymethyl chitosan (CMC) as materials, and leaf mustard as research objective,effects of different concentration of CTS and CMC coatings on postharvest quality of leaf mustard were investigated via determining sensory evaluation，water loss rate，ascorbic acid，chlorophyll content and total phenols content.The leaf mustards were stored in refrigeratory at 4℃ and 75% humidity.The results showed that 0.6% CMC treatments could retard the leaf mustards’ transpiration effectively and reduce the loss of ascorbic acid，chlorophyll content and total phenols content.On the fifth day，the sensory evaluation of control group reached to a unacceptable level (under 7.0)，whereas the 0.6% CMC treatments reached the same level after 4 days.On the ninth day，the water loss rate of 0.6% CMC and control group were 13.7% and 19.3%，respectively.The chlorophyll content of 0.6% CMC and control group were 0.23 mg/100gFW and 0.18 mg/100gFW respectively at that time.Also，the 0.6% CMC treatments had a good effect on retarding the ascorbic acid and total phenols content.
