Storage, preservation and processing technology of eggplant

every summer and autumn, after a large number of eggplants are listed, they are often overstocked and wasted due to unsalable products. This paper introduces several storage and fresh-keeping methods of Eggplant and the processing technology of flavored food

I. storage and preservation of eggplant

choose a place with high and dry terrain and good drainage to dig ditches, with a depth of 1.2 meters, a width of 1 ~ 1.5 meters, and the length depends on the number of eggplants. Before storage, choose eggplants that are free of mechanical injury, insect injury, and disease, and often have the same thermal insulation material. Medium-sized healthy eggplant fruits are stored in the shade, and enter the ditch after the temperature drops

when entering the ditch, stack the fruit handle one layer down. The second layer of fruit handle should be inserted into the first layer of fruit to provide fuel gap for transportation and aviation departments to prevent stabbing good fruit. Stack 4-5 layers in this way, cover the top layer with kraft paper or weeds, and then cover the soil layer by layer with the decrease of temperature. In order to prevent the eggplant from generating heat in the ditch, when the eggplant is buried, an air duct and a temperature measuring tube can be erected every 3 ~ 4 meters to maintain the appropriate temperature in the ditch. If the temperature is too low, the soil layer should be thickened and the ventilation duct should be blocked tightly; If the temperature is too high, open the ventilator. This method can generally keep eggplant fresh for 40 ~ 60 days
