Can mango be kept fresh in refrigerator
Mango belongs to tropical fruit, not suitable for storage in the refrigerator. Mango skin will turn black when it is stored at a temperature of more than ten degrees Celsius, because the temperature of the environment in which it grows is not suitable for being too cold. Once it is kept for a long time, it will accelerate its decay. However, generally speaking, it can be placed in the fruit heat preservation cabinet in the refrigerator. The temperature should not be very low, and it is OK to store it temporarily, but it should not be stored for a long time. After it is taken out of the refrigerator, it will accelerate under normal temperature Bad, so eat as soon as possible.
How to keep mango from rotting
1. Pre storage treatment: Mango must be stored as soon as possible after harvest. In order to improve the storage effect, proper treatment should be carried out before storage. The mango used for storage shall be selected from the non damaged and good fruits free of pests and diseases, and the selected good fruits shall be cleaned to remove the stains and juice overflowing from the handle. At the same time of fruit washing, the best combination of antiseptic and bactericidal treatment can prevent the occurrence of anthrax and foot rot. After soaking the fruit, take it out, spread it out to dry, and then pack and store it.
2. Low temperature storage: wash the spilled juice from the wounds of the fruit handle with clear water, then soak the fruit in 500-1000ppm water solution of 52 ℃ for 50 minutes and dry it. Wrap them one by one with breathable cotton rib paper, carefully pack them in boxes or put them in fruit baskets. The boxes and baskets should be padded with hay, and the amount of fruit should be 15-20 kg. Put it in the ventilation environment of 20 ℃ for 1-2 days, then put it in the indoor storage environment of 15 ℃ for 1-2 days, and then put it in the environment of 10-12 ℃ for storage, keeping the relative humidity at 85-90%.
3. Controlled atmosphere storage: after antiseptic and antiseptic treatment, precooling and perspiration, the good fruit is packed with polyethylene film bag and sealed at the bottom. The gas composition of low oxygen and high carbon dioxide is formed by its own respiration. The storage and transportation time of mango can be prolonged for 2-15 days, and the storage period is about 1 month. However, it should be noted that polyethylene film bags should be removed at the end of storage to prevent carbon dioxide damage. After storage, mango should be ripened at 21-24 ℃ to improve its quality and flavor.
Fruit that can't be kept in the refrigerator
1. Banana: if the banana is stored below 12 ℃, it will turn black and rotten, and the refrigerator's cold room is zero. Some tropical fruits, such as green bananas, which are not ripe when they are bought back, have worse cold resistance, so it's better not to put them in the refrigerator. Otherwise, it will not only not mature normally, but also rot and cannot be eaten.
2. Tomato: after freezing at low temperature, the meat will be in the shape of blister, soft rotten or spallation, and there will be black spots on the surface, not cooked, no fresh taste, or even rancidity. It is suggested to store it in a dry and low temperature place to keep the flavor as much as possible.
3. Durian: Durian has a late ripening nature. It should be stored in a cool place. The ripened fruit will crack. At this time, the pulp can be taken out and stored in a fresh-keeping bag in the refrigerator. After being frozen, it will have the taste of ice cream. If the flesh becomes rancid, it means that durian has gone bad and should not be eaten.
4. Mango: mango is a tropical fruit. It likes drought and is most afraid of low temperature. Therefore, it's better not to put mango in the refrigerator, or the peel will turn black. Therefore, it's not suitable to buy too much mango every time. If you can't eat it all at once, you'd better choose some slightly green mango when you buy it and let it ripen naturally at 20-25 ℃.
5. Papaya: papaya is also a fruit that can't be stored in the refrigerator. As long as papaya touches water, there will be black spots. Although the refrigerator has the effect of absorbing water, once the refrigerator is taken out, the temperature difference will make the surface of papaya appear water, and there will be no fresh black spots. The right way to keep papaya is to wrap it in newspaper and put it in a cool place. In this way, papaya can be preserved for a long time, and keep fresh all the time.
6. Longan: longan is preserved at 1-2 ℃, the color of exocarp will turn dark, and the inner pericarp will appear spots like scald. Such fruits can't be eaten any more.
7. Litchi: when fresh litchi is placed in the environment of 0 ℃ for one day, the skin will turn black and the flesh will turn taste. You can cut off the long stem of litchi, and then put litchi into a plastic bag, and tie the bag tightly, and place it in a cool place. If possible, the plastic bag containing litchi can be immersed in water. In this way, the color, fragrance and taste of litchi remain unchanged after a few days.
8. Pineapple: when pineapple is preserved at 6-10 ℃, not only the peel will change color, but also the pulp will be soaked in water. It is best to store in a dark and cool place.
