- Abstract
Taigu pear jujube often appears unfavorable storage phenomena, such as cracking, moldiness and decline of quality after harvest because its mature period is rainy season. As a result, the shelf life of fresh fruit is shortened and the commodity quality has decreased. In order to extend its shelf life, a kind of core-shell structure fresh-keeping coating with beta zeolite as the core phase and chitosan as the shell phase was prepared, and the effects of different ratios of the beta zeolite and chitosan on the post-harvest quality of Taigu pear jujube were further explored. The best ratio of beta zeolite and chitosan in fresh-keeping coating was explored through testing the hardness, weight loss rate, cell membrane permeability and soluble solid content. The results showed that after 70 days, the respiratory intensity of Taigu pear jujube treated with the fresh-keeping coating with the quality ratio of beta zeolite and chitosan of 1∶1.5 was 43.99 mg·kg-1·h-1, its hardness was 4.99 N. Compared to the initial situation, hardness remained 42%, its weight loss rate was 2.45%, its permeability of cell membrane increased by 48.67%, its soluble solid content decreased. These results suggested that beta @chitosan fresh-keeping coating could delay the increase of weight loss rate and cell membrane permeability of Taigu pear jujube to a certain extent, and inhibit the decrease of hardness and soluble solid content, thus improving the fruit storage quality.
