Abstract:

In order to improve disease resistance and extend storage time, color development, incidence and quality property of winter jujube with pre-harvested chitosan treatment and post-harvested ultraviolet-C (UV-C) treatment were analyzed during storage. Results indicated that chitosan treatment and 0.5－1 kJ/m2 UV-C irradiation could promote the color development, reduce the infection rate and disease index, and postpone disease incidence for 3－6 days. In addition, 0.5－1 kJ/m2 UV-C treatment could retain the contents of total acids, total sugar and vitamin C, and improve the product quality. However, chitosan treatment had not significant effect on the quality of winter jujube.

Key words: chitosan, ultraviolet-C (UV-C), winter jujube, storage quality
