一种光控制释放一氧化氮的海藻酸钠涂层及其制备方法和应用
摘要：
本发明公开了一种光控制释放一氧化氮的海藻酸钠涂层，所述涂层主要由能够在光照条件下释放一氧化氮的环碳酸酯单体和海藻酸钠制成。将环碳酸酯单体溶解后，用海藻酸钠溶液稀释，将底物浸泡在所得混合溶液中，取出风干，在底物表面即得所述光控制释放一氧化氮的海藻酸钠涂层。相对于现有技术，本发明所得光控制释放一氧化氮的海藻酸钠涂层，能够在LED灯照射下缓慢释放一氧化氮，提高果蔬的抗衰老能力，延缓果蔬的货架期。并且制备方法工序合理、操作简单、便宜易得，果蔬的贮藏保鲜效果好，可控性好，有较好的应用前景。
摘要（英）：

The invention discloses a light-control nitric oxide release sodium alginate coating. The coating is mainly prepared from a cyclocarbonate monomer for releasing nitric oxide under the condition of illumination and sodium alginate. The coating is prepared through the steps of enabling the cyclocarbonate monomer to dissolve, performing diluting with a sodium alginate solution, soaking a substrate inthe obtained mixed solution, performing taking out, performing air drying, and obtaining the light-control nitric oxide release sodium alginate coating on the surface of the substrate. Compared withthe prior art, the obtained light-control nitric oxide release sodium alginate coating can slowly release nitric oxide under the irradiation by an LED lamp, so that the ageing resistance of fruits andvegetables can be improved, and the shelf life of the fruits and vegetables can be prolonged. The preparation method is reasonable in working procedures and simple to operate, the light-control nitric oxide release sodium alginate coating is cheap and easy to obtain, the storage and fresh keeping effect of the fruits and vegetables is good, the controllability is good, and the light-control nitric oxide release sodium alginate coating has good application prospects.
