Abstract:

The coating(shellac rosin coating,SC)produced with shellac,rosin and HPMC (Hydroxypropyl methyl cellulose)was used to treat satsuma mandarin and Lane Late navel orange fruit and then the brightening and preservation effects were evaluated. The results showed that SC treatment could significantly increase glossiness of the skin,reduce the rate of weight loss,delay shrinkage and the color change of the skin,reduce the respiration rate,enhance the TSS and TA content and control the off-flavor under human perception threshold during the shelf life. The SEM observation revealed that the epicuticular wax structure was uniform and complete under SC treatment.

Key words: citrus, postharvest, shellac, rosin, coating, glossiness
