Embodiment 1
[0017] ①Pretreatment: low maturity (with 0.05~0.1mol / L iodine solution applied to the cross-sectioned fruit surface, the dyed fruit accounts for the total number of fruit, that is, the dyed fruit rate is 81%-100%, and the hardness is 5.3-5.6Kg·cm -2 After picking the yellow crown pear of ), select the pear fruit with uniform size, no peel brown spot, no mechanical injury, no disease and insect damage, no deformity, a single fruit cover with fresh-keeping paper, a net cover, and put into a carton lined with a fresh-keeping bag;
[0018] ②Browning inhibition treatment: Put Huangguan pear in a storage warehouse with ethylene slow-release agent, and fumigate with ethylene for 4 hours at a temperature of 25 °C, and the fumigation concentration is 10,000 μL / L (V / V);
[0019] ③ Packing: After fumigation, the temperature of Huangguan pear is controlled at -1℃~0℃, and the humidity is controlled at 60~70%.
[0020] The fruit treated by the method has no browning of peel, and the brownin...
Embodiment 2
[0022] Under the condition of temperature of 20°C, ethylene fumigation was performed for 16 hours, and the fumigation concentration was 1000 μL / L (V / V). The quality of pears and other operations were the same as those in Example 1. The treatment by the method can effectively inhibit the browning of the peel, the browning rate of the control without treatment reaches 80%, no browning after the fumigation treatment, and the storage quality is also better than the control.
Embodiment 3
[0024] Under the condition of temperature of 35°C, ethylene fumigation was carried out for 30 hours, and the fumigation concentration was 100 μL / L (V / V). The quality of pears and other operations were the same as those in Example 1. The treatment by the method can effectively inhibit the browning of the peel, the browning rate of the control without treatment reaches 80%, no browning after the fumigation treatment, and the storage quality is also better than the control.
