Under the conditions of low oxygen and high carbon dioxide, due to reducing the respiratory intensity and limiting the synthesis of ethylene in the body, and preventing the role of ethylene, so as to prevent the shedding of eggplant and reduce eggplant fruit rot. This method can store eggplant fruit for about 30 days and maintain the original commercial value of eggplant fruit. Some people use 10 μ m thick high-density polyethylene bag to store the selected eggplant fruit in small packaging.
