1. After pre cooling, the peaches were packaged in plastic bags and stored in the refrigerator. The temperature was controlled at 0 ℃ and the relative humidity was controlled at 85% - 90%. The storage period could reach 1 month.
2. The results showed that the storage period of peaches could be prolonged for 6 weeks in the modified atmosphere environment with 0 ℃, 85% - 90% relative humidity, 5% carbon dioxide and 1% oxygen. If brick or zeolite soaked in potassium permanganate is added into the modified atmosphere bag to absorb ethylene, the effect will be better. It is reported that the modified atmosphere storage with bag and CT series of Ca preservatives can be stored for 2 months at 0 ℃ - 2 ℃, and at least 8-10 days at 25 ℃ - 30 ℃.
3. When there is no mechanical cold storage in North China, ice cellar can be used to store winter peach and other more durable varieties. In areas where there is no natural ice source, artificial ice can be made in the cold season. The specific method is to cut the ice into large pieces of ice 30 cm-40 cm thick, 1 m long and 1 m wide, and put them in the cellar. Straw with a thickness of 40 cm-50 cm is laid at the bottom of the cellar to prevent water accumulation after ice melting, and then seal the cellar door to store ice. When the peaches are ripe, remove the ice in the cellar, stack a layer of ice 40 cm thick at the bottom and around the cellar, stack the peaches packed in boxes or baskets on the ice, and fill the packages with broken ice, and put a layer of ice on the top of each layer. After stacking, the top layer is covered with 1 m thick heat insulation materials such as sawdust or rice straw. The cellar door must be sealed tightly. When the cellar must be opened for inspection, the working time should be shortened as far as possible. The temperature of the pit should be kept at 0 ℃ - 1 ℃. Once the ice melting temperature rises, peaches should be taken out of the cellar immediately.
4. The suitable temperature and relative humidity are - 0.5 ℃ - 0 ℃ and 90% respectively. In order to store for a long time, the temperature of the cold storage must be strictly controlled, and the temperature of the cold storage should not fluctuate. In the early stage of storage, proper ventilation should be adopted. Under the condition of low temperature, chilling injury symptoms will appear after 2 weeks. When the fruit is ripened in high temperature environment, the pulp will become dry, soft and soft, and the pulp around the core will become brown obviously. When the fruit is serious, the skin can see patterns, and the color of the skin is dim and dull, and the flavor changes. Peaches stored at 2 ℃ - 5 ℃ were more likely to deteriorate than those stored below 0 ℃. The varieties with good quality could be stored for 4 weeks at - 0.5 ℃ - 0 ℃. Peach cold storage time is too long, will be tasteless, therefore, its storage period should not be too long.
5. Chemical storage method peach during storage, often because of brown rot caused by a large number of decay. The results showed that the decay of peach could be prevented by soaking 0.1% benomyl suspension at 40 ℃ for 25 min before storage.
So, how to keep fresh peaches? These methods are all OK, but the quantity is small and the cost is decided by ourselves!
